The "WireUpCoreRuntime" task failed unexpectedly Visual studio 2017

I experienced the same error renaming the Assembly name for a UWP application.

I discovered you also need to open Package.appxmanifest and change the Entry point to the same value you used in Assembly name.

I messed up with appxmanifest file. I use AppServices for background work. In this example they have got some changes in appxmanifest file, but they suddenly throws error.

    <Application Id="AppServicesProvider.App"
      Executable="$targetnametoken$.exe"
      EntryPoint="AppServicesProvider.App">

Have to be simplified into

<Application Id="App">

And it throws no error anymore.
