-      or a Contribution incorporated within the Work constitutes direct
-      or contributory patent infringement, then any patent licenses
-      granted to You under this License for that Work shall terminate
-      as of the date such litigation is filed.
-
-   4. Redistribution. You may reproduce and distribute copies of the
-      Work or Derivative Works thereof in any medium, with or without
-      modifications, and in Source or Object form, provided that You
-      meet the following conditions:
-
-      (a) You must give any other recipients of the Work or
-          Derivative Works a copy of this License; and
-
-      (b) You must cause any modified files to carry prominent notices
-          stating that You changed the files; and
-
-      (c) You must retain, in the Source form of any Derivative Works
-          that You distribute, all copyright, patent, trademark, and
-          attribution notices from the Source form of the Work,
-          excluding those notices that do not pertain to any part of
-          the Derivative Works; and
-
-      (d) If the Work includes a "NOTICE" text file as part of its
-          distribution, then any Derivative Works that You distribute must
-          include a readable copy of the attribution notices contained
-          within such NOTICE file, excluding those notices that do not
-          pertain to any part of the Derivative Works, in at least one
-          of the following places: within a NOTICE text file distributed
-          as part of the Derivative Works; within the Source form or
-          documentation, if provided along with the Derivative Works; or,
-          within a display generated by the Derivative Works, if and
-          wherever such third-party notices normally appear. The contents
-          of the NOTICE file are for informational purposes only and
-          do not modify the License. You may add Your own attribution
-          notices within Derivative Works that You distribute, alongside
-          or as an addendum to the NOTICE text from the Work, provided
-          that such additional attribution notices cannot be construed
-          as modifying the License.
-
-      You may add Your own copyright statement to Your modifications and
-      may provide additional or different license terms and conditions
-      for use, reproduction, or distribution of Your modifications, or
-      for any such Derivative Works as a whole, provided Your use,
-      reproduction, and distribution of the Work otherwise complies with
-      the conditions stated in this License.
-
-   5. Submission of Contributions. Unless You explicitly state otherwise,
-      any Contribution intentionally submitted for inclusion in the Work
-      by You to the Licensor shall be under the terms and conditions of
-      this License, without any additional terms or conditions.
-      Notwithstanding the above, nothing herein shall supersede or modify
-      the terms of any separate license agreement you may have executed
-      with Licensor regarding such Contributions.
-
-   6. Trademarks. This License does not grant permission to use the trade
-      names, trademarks, service marks, or product names of the Licensor,
-      except as required for reasonable and customary use in describing the
-      origin of the Work and reproducing the content of the NOTICE file.
-
-   7. Disclaimer of Warranty. Unless required by applicable law or
-      agreed to in writing, Licensor provides the Work (and each
-      Contributor provides its Contributions) on an "AS IS" BASIS,
-      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
-      implied, including, without limitation, any warranties or conditions
-      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
-      PARTICULAR PURPOSE. You are solely responsible for determining the
-      appropriateness of using or redistributing the Work and assume any
-      risks associated with Your exercise of permissions under this License.
-
-   8. Limitation of Liability. In no event and under no legal theory,
-      whether in tort (including negligence), contract, or otherwise,
-      unless required by applicable law (such as deliberate and grossly
-      negligent acts) or agreed to in writing, shall any Contributor be
-      liable to You for damages, including any direct, indirect, special,
-      incidental, or consequential damages of any character arising as a
-      result of this License or out of the use or inability to use the
-      Work (including but not limited to damages for loss of goodwill,
-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
-
-   9. Accepting Warranty or Additional Liability. While redistributing
-      the Work or Derivative Works thereof, You may choose to offer,
-      and charge a fee for, acceptance of support, warranty, indemnity,
-      or other liability obligations and/or rights consistent with this
-      License. However, in accepting such obligations, You may act only
-      on Your own behalf and on Your sole responsibility, not on behalf
-      of any other Contributor, and only if You agree to indemnify,
-      defend, and hold each Contributor harmless for any liability
-      incurred by, or claims asserted against, such Contributor by reason
-      of your accepting any such warranty or additional liability.

-# JavaScriptServices
+This branch exists only to build `Microsoft.AspNetCore.SpaServices.Extensions` for an OOB release. It does not contain sources for any other packages or samples.
-
-AppVeyor: [![AppVeyor](https://ci.appveyor.com/api/projects/status/gprilrckx116vc9m/branch/dev?svg=true)](https://ci.appveyor.com/project/aspnetci/javascriptservices/branch/dev)
-
-This project is part of ASP.NET Core. You can find samples, documentation and getting started instructions for ASP.NET Core at the [Home](https://github.com/aspnet/home) repo.
-
-## What is this?
-
-`JavaScriptServices` is a set of client-side technologies for ASP.NET Core. It provides infrastructure that you'll find useful if you:
-
--  Use Angular / React / Vue / Aurelia / Knockout / etc.
--  Build your client-side resources using Webpack.
--  Execute JavaScript on the server at runtime.
-
-Read [Building Single Page Applications on ASP.NET Core with JavaScriptServices](https://blogs.msdn.microsoft.com/webdev/2017/02/14/building-single-page-applications-on-asp-net-core-with-javascriptservices/) for more details.
-
-This repo contains:
-
- * A set of NuGet/NPM packages that implement functionality for:
-   * Invoking arbitrary NPM packages at runtime from .NET code ([docs](/src/Microsoft.AspNetCore.NodeServices#simple-usage-example))
-   * Server-side prerendering of SPA components ([docs](/src/Microsoft.AspNetCore.SpaServices#server-side-prerendering))
-   * Webpack dev middleware ([docs](/src/Microsoft.AspNetCore.SpaServices#webpack-dev-middleware))
-   * Hot module replacement (HMR) ([docs](/src/Microsoft.AspNetCore.SpaServices#webpack-hot-module-replacement))
-   * Server-side and client-side routing integration ([docs](/src/Microsoft.AspNetCore.SpaServices#routing-helper-mapspafallbackroute))
-   * Server-side and client-side validation integration
-   * "Lazy loading" for Knockout apps
- * Samples and docs
-
-It's cross-platform (Windows, Linux, or macOS) and works with .NET Core 2.0 or later.
-
-## Creating new applications
-
-Prerequisites:
-
-* [.NET Core 2.0](https://www.microsoft.com/net/core) (or later) SDK
-* [Node.js](https://nodejs.org/) version 6 (or later)
-
-With these prerequisites, you can immediately create new ASP.NET Core applications that use Angular, React, or React+Redux without having to install anything extra.
-
-### Option 1: Creating Angular/React/Redux applications from the command line (cross-platform)
-
-In an empty directory, run (for example) `dotnet new angular`. Other supported SPA frameworks include React and React+Redux. You can see the list of available SPA templates by running `dotnet new spa`.
-
-Once the generator has run and restored all the dependencies, you can start up your new ASP.NET Core SPA:
-
-    npm install
-    dotnet run
-
-### Option 2: Creating Angular/React/Redux applications using Visual Studio 2017 Update 3 or later (Windows only)
-
-Using the `File`->`New Project` dialog, select *ASP.NET Core Web Application*. You will then be offered the option to create an application with Angular, React, or React+Redux. When the application is created, you can build and run it in the normal way.
-
-### More info and other SPA frameworks
-
-For a more detailed (albeit somewhat outdated) walkthrough, see [getting started with the `aspnetcore-spa` generator](http://blog.stevensanderson.com/2016/05/02/angular2-react-knockout-apps-on-aspnet-core/).
-
-If you want to build an ASP.NET Core application with Aurelia, Knockout, or Vue, you can use the `Microsoft.AspNetCore.SpaTemplates` package. On the command line, run `dotnet new --install Microsoft.AspNetCore.SpaTemplates`. Then you will be able to run `dotnet new aurelia` (or `dotnet new vue`, etc.) to create your new application.
-
-## Adding to existing applications
-
-If you have an existing ASP.NET Core application, or if you just want to use the underlying JavaScriptServices packages directly, you can install these packages using NuGet and NPM:
-
- * `Microsoft.AspNetCore.NodeServices`
-   * This provides a fast and robust way for .NET code to run JavaScript on the server inside a Node.js environment. You can use this to consume arbitrary functionality from NPM packages at runtime in your ASP.NET Core app.
-   * Most applications developers don't need to use this directly, but you can do so if you want to implement your own functionality that involves calling Node.js code from .NET at runtime.
-   * Find [documentation and usage examples here](/src/Microsoft.AspNetCore.NodeServices#microsoftaspnetcorenodeservices).
- * `Microsoft.AspNetCore.SpaServices`
-   * This provides infrastructure that's generally useful when building Single Page Applications (SPAs) with technologies such as Angular or React (for example, server-side prerendering and webpack middleware). Internally, it uses the `NodeServices` package to implement its features.
-   * Find [documentation and usage examples here](/src/Microsoft.AspNetCore.SpaServices#microsoftaspnetcorespaservices)
-
-There were previously other packages called  `Microsoft.AspNetCore.AngularServices` and `Microsoft.AspNetCore.ReactServices` but these are not currently needed - all applicable functionality is in `Microsoft.AspNetCore.SpaServices`, because it's sufficiently general.
-
-If you want to build a helper library for some other SPA framework, you can do so by taking a dependency on `Microsoft.AspNetCore.SpaServices` and wrapping its functionality in whatever way is most useful for your SPA framework.
-
-## Samples
-
-The [`samples` directory](/samples) contains examples of:
-
-- Using the JavaScript services family of packages with Angular and React.
-- A standalone `NodeServices` usage for runtime code transpilation and image processing.
-
-**To run the samples:**
-
- * Clone this repo
- * At the repo's root directory (the one containing `src`, `samples`, etc.), run `dotnet restore`
- * Change directory to the sample you want to run (for example, `cd samples/angular/MusicStore`)
- * Restore Node dependencies by running `npm install`
-   * If you're trying to run the Angular "Music Store" sample, then also run `gulp` (which you need to have installed globally). None of the other samples require this.
- * Run the application (`dotnet run`)
- * Browse to [http://localhost:5000](http://localhost:5000)
-
-## Contributing
-
-If you're interested in contributing to the various packages, samples, and project templates in this repo, that's great!
-
-Before working on a pull request, especially if it's more than a trivial fix (for example, for a typo), it's usually a good idea first to file an issue describing what you're proposing to do and how it will work. Then you can find out if it's likely that such a pull request will be accepted, and how it fits into wider ongoing plans.

-            In general, we want the Node child processes to be terminated as soon as the parent .NET processes exit,
-            because we have no further use for them. If the .NET process shuts down gracefully, it will run its
-            finalizers, one of which (in OutOfProcessNodeInstance.cs) will kill its associated Node process immediately.
-            
-            But if the .NET process is terminated forcefully (e.g., on Linux/OSX with 'kill -9'), then it won't have
-            any opportunity to shut down its child processes, and by default they will keep running. In this case, it's
-            up to the child process to detect this has happened and terminate itself.
-            
-            There are many possible approaches to detecting when a parent process has exited, most of which behave
-            differently between Windows and Linux/OS X:
-            
-             - On Windows, the parent process can mark its child as being a 'job' that should auto-terminate when
-               the parent does (http://stackoverflow.com/a/4657392). Not cross-platform.
-             - The child Node process can get a callback when the parent disconnects (process.on('disconnect', ...)).
-               But despite http://stackoverflow.com/a/16487966, no callback fires in any case I've tested (Windows / OS X).
-             - The child Node process can get a callback when its stdin/stdout are disconnected, as described at
-               http://stackoverflow.com/a/15693934. This works well on OS X, but calling stdout.resume() on Windows
-               causes the process to terminate prematurely.
-             - I don't know why, but on Windows, it's enough to invoke process.stdin.resume(). For some reason this causes
-               the child Node process to exit as soon as the parent one does, but I don't see this documented anywhere.
-             - You can poll to see if the parent process, or your stdin/stdout connection to it, is gone
-               - You can directly pass a parent process PID to the child, and then have the child poll to see if it's
-                 still running (e.g., using process.kill(pid, 0), which doesn't kill it but just tests whether it exists,
-                 as per https://nodejs.org/api/process.html#process_process_kill_pid_signal)
-               - Or, on each poll, you can try writing to process.stdout. If the parent has died, then this will throw.
-                 However I don't see this documented anywhere. It would be nice if you could just poll for whether or not
-                 process.stdout is still connected (without actually writing to it) but I haven't found any property whose
-                 value changes until you actually try to write to it.
-            
-            Of these, the only cross-platform approach that is actually documented as a valid strategy is simply polling
-            to check whether the parent PID is still running. So that's what we do here.

-In general, we want the Node child processes to be terminated as soon as the parent .NET processes exit,
-because we have no further use for them. If the .NET process shuts down gracefully, it will run its
-finalizers, one of which (in OutOfProcessNodeInstance.cs) will kill its associated Node process immediately.
-
-But if the .NET process is terminated forcefully (e.g., on Linux/OSX with 'kill -9'), then it won't have
-any opportunity to shut down its child processes, and by default they will keep running. In this case, it's
-up to the child process to detect this has happened and terminate itself.
-
-There are many possible approaches to detecting when a parent process has exited, most of which behave
-differently between Windows and Linux/OS X:
-
- - On Windows, the parent process can mark its child as being a 'job' that should auto-terminate when
-   the parent does (http://stackoverflow.com/a/4657392). Not cross-platform.
- - The child Node process can get a callback when the parent disconnects (process.on('disconnect', ...)).
-   But despite http://stackoverflow.com/a/16487966, no callback fires in any case I've tested (Windows / OS X).
- - The child Node process can get a callback when its stdin/stdout are disconnected, as described at
-   http://stackoverflow.com/a/15693934. This works well on OS X, but calling stdout.resume() on Windows
-   causes the process to terminate prematurely.
- - I don't know why, but on Windows, it's enough to invoke process.stdin.resume(). For some reason this causes
-   the child Node process to exit as soon as the parent one does, but I don't see this documented anywhere.
- - You can poll to see if the parent process, or your stdin/stdout connection to it, is gone
-   - You can directly pass a parent process PID to the child, and then have the child poll to see if it's
-     still running (e.g., using process.kill(pid, 0), which doesn't kill it but just tests whether it exists,
-     as per https://nodejs.org/api/process.html#process_process_kill_pid_signal)
-   - Or, on each poll, you can try writing to process.stdout. If the parent has died, then this will throw.
-     However I don't see this documented anywhere. It would be nice if you could just poll for whether or not
-     process.stdout is still connected (without actually writing to it) but I haven't found any property whose
-     value changes until you actually try to write to it.
-
-Of these, the only cross-platform approach that is actually documented as a valid strategy is simply polling
-to check whether the parent PID is still running. So that's what we do here.
