The "IsFileSystemCaseSensitive" parameter is not supported by the "FindConfigFiles" task error.

    I've recently started working on a small project with angular used on the front end. Part of it was adding the project from template (I've used a popular scaffolding Angular2WebTemplate). I've installed required nugets: Microsoft.TypeScript.Compiler and Microsoft.TypeScript.MSBuild.

After first build I've received the following error:
The "IsFileSystemCaseSensitive" parameter is not supported by the "FindConfigFiles" task error.

It took me a bit of digging to find this:
https://github.com/Microsoft/TypeScript/issues/15536

The issue seems to have been caused by two imports covering 2 different version of the same targets file. The solution was to remove one of the imports. Below a solution pasted from the above url:

Remove the local import (or Nuget import which ever one you choose). 

• local

 <Import Project="$(MSBuildExtensionsPath32)\Microsoft\VisualStudio\v$(VisualStudioVersion)\TypeScript\Microsoft.TypeScript.targets" Condition="Exists('$(MSBuildExtensionsPath32)\Microsoft\VisualStudio\v$(VisualStudioVersion)\TypeScript\Microsoft.TypeScript.targets')" />

• Nuget - should be near the end of the proj file

 <Import Project="..\packages\Microsoft.TypeScript.MSBuild.2.3.1\build\Microsoft.TypeScript.MSBuild.targets" Condition="Exists('..\packages\Microsoft.TypeScript.MSBuild.2.3.1\build\Microsoft.TypeScript.MSBuild.targets')" />

In my case I've removed the first entry which was enough to make the project compile and run.
