I've been battling this error (supposedly related to AOT) even using the newer templates that don't have the include: '/ClientApp' in the webpack.config.js. Here are my steps for reproducing it:

Start with a new template dotnet new angular
Remove jQuery and bootstrap references from the package.json, webpack.config.vendor.js, and boot.browser.ts
Run the following: npm install webpack --config .\webpack.config.vendor.js --env.prod webpack --env.prod
start updating the remaining packages in the package.json to the latest versions
run the commands in step 3 again, and you'll get get the following error:

ERROR in ./ClientApp/boot.server.ts
Module not found: Error: Can't resolve './../$$_gendir/ClientApp/app/app.server.module.ngfactory' in 'C:\Users\xxxxx\Documents\Visual Studio 2017\Projects\testapp2\ClientApp'
@ ./ClientApp/boot.server.ts 8:0-94

    at run (bootstrap_node.js:393:7)
    at startup (bootstrap_node.js:150:9)

Once the error starts, even reverting changes won't make it go away.
