File to transform not found / wwwroot folder / ASP.NET Core 1.1 about slow-cheetah

[jviau]

From that callstack the file name looks weird: D:\myproject\wwwroot\enviroment.json;D:\myproject\wwwroot\enviroment.json Does your project file have that exact string in it?

The project file looks like this (just reproduced it in a new project):

<Project Sdk="Microsoft.NET.Sdk.Web">

  <PropertyGroup>
    <TargetFramework>net452</TargetFramework>
    <RuntimeIdentifier>win7-x86</RuntimeIdentifier>
  </PropertyGroup>

  <ItemGroup>
    <None Include="wwwroot\environment.Debug.json">
      <IsTransformFile>True</IsTransformFile>
    </None>
    <Content Include="wwwroot\environment.json" />
    <None Include="wwwroot\environment.Release.json">
      <IsTransformFile>True</IsTransformFile>
    </None>
  </ItemGroup>
  <ItemGroup>
    <PackageReference Include="Microsoft.ApplicationInsights.AspNetCore" Version="2.0.0" />
    <PackageReference Include="Microsoft.AspNetCore" Version="1.1.2" />
    <PackageReference Include="Microsoft.AspNetCore.Mvc" Version="1.1.3" />
    <PackageReference Include="Microsoft.Extensions.Logging.Debug" Version="1.1.2" />
    <PackageReference Include="Microsoft.VisualStudio.SlowCheetah" Version="3.0.61" />
  </ItemGroup>
  <ItemGroup>
    <DotNetCliToolReference Include="Microsoft.VisualStudio.Web.CodeGeneration.Tools" Version="1.0.1" />
  </ItemGroup>
  <ItemGroup>
    <Content Update="wwwroot/environment.json">
      <TransformOnBuild>true</TransformOnBuild>
    </Content>
  </ItemGroup>

</Project>

Publish to folder reveals the same error.

.netcore projects already include all items via glob, so this may be due to msbuild items being duplicated. Can you try changing to:

<Content Update="wwwroot/environment.json">
  <TransformOnBuild>true</TransformOnBuild>
</Content>
<Content Update="wwwroot/environment.Debug.json">
  <IsTransformFile>True</IsTransformFile>
</Content>
<Content Update="wwwroot/environment.Release.json">
  <IsTransformFile>True</IsTransformFile>
</Content>

Remove the None Includes and the Content Include. Also, the contents of the wwwroot folder may be copied to the output directory by default, if that is the case and it runs after slow cheetah, that copy will overwrite the transform. If that happens you want to find those items in the solution explorer and set copy to output "never"

Closing for now. Re-open if my last reply did not solve your issue.
