VS2017 - Template Core projects do not start

I am using the most updated version of VS 2017 (version 15.2 - 26430.6- release) and I am trying to use the ASP.Net Core templates.

I tried ASP.Net Core Web Application (.NET Core) both with ASP.NET Core 1.0 and 1.1 for the Empty and the Web Application templates and I always get the following when I try to run it:

code:-32000
message:No script for id: 31
The program '[8268] dotnet.exe' has exited with code -2147450749 (0x80008083).
The program '[6432] chrome.exe: WebKit' has exited with code -1 (0xffffffff).
The program '[8656] iisexpress.exe' has exited with code 0 (0x0).

I have checked my .NET Core and I have the latest SDK plus the latest LTS and Current installations. Even a simple .NET Core console app can not be launched...

I also tried some solutions here but nothing.

Any advices as it gets really frustrating.

Cheers

OK after making several tests, it seems that the new templates are based on Microsoft.NETCore.App 1.1.2 which prevents the application to launch correctly.

If I add in my .csproj file:

  <PropertyGroup>
    <TargetFramework>netcoreapp1.1</TargetFramework>
    <RuntimeFrameworkVersion>1.1.1</RuntimeFrameworkVersion>
  </PropertyGroup>

instead of

  <PropertyGroup>
    <TargetFramework>netcoreapp1.1</TargetFramework>        
  </PropertyGroup>

It works.

I also have to remove the Nuget package named Microsoft.VisualStudio.Web.codegeneration.Design 1.1.1 which relies on the Microsoft.NETCore.App 1.1.2.

Would it be a bug with 1.1.2 or a misuse in the templates?

Thanks
