Title

Webpack dev middleware writes files to disk
Documentation states;

They don't need to be written to disk - they are just held in memory and served directly to the browser.

(Ref: https://github.com/aspnet/JavaScriptServices/tree/dev/src/Microsoft.AspNetCore.SpaServices#webpack-dev-middleware)

Currently when I run the project (unedited, generated React/Redux template) files are written to the dist.

Apologies if I'm not running it correctly! 😄

Functional impact

Files are written to disk, they shouldn't be.

Minimal repro steps

dotnet new reactredux
dotnet run
View wwwroot/dist, directory and contents will be visible

Expected result

dist directory to be non-existant, files to be served without disk write.

Actual result

dist and all files are built and written to disk.

Further technical details

When using Webpack's dev server/middleware files are not written to disk, they are served from memory only. I can only assume there is a config issue somewhere.
