Can't Build aspnetcore app in VS 2017 RC

After installing the new VS 2017 RC I'm having issues with building my asnetcore app, here is the error that I am receiving:

MSB4131 The "FilesWritten" parameter is not supported by the "GenerateRuntimeConfigurationFiles" task. Verify the parameter exists on the task, and it is a gettable public instance property.

Here is my .csproj file:

So it looks like this was related to having multiple projects with different msbuild tools versions.

I had older projects that weren't using the new convention of referencing the tools: ToolsVersion="15.0" Sdk="Microsoft.NET.Sdk.Web"...

Once I changed them to use this convention everything started to work.

  1. Launch Task Manager
  2. end all existing MSBuild tasks.
  3. Rebuild your project(s). it should work just fine.

Beside. your .csproj looks just fine to me; however, it looks like its setup to run in two different environment perhaps console and aspcore 1.0
