VS 2015 remote debugging fails when using TypeScriptCompile

[Cristi003]

VS Typescript Extension version: 1.7.6

Steps to reproduce

Create a javascript windows app and add a typescript file in a sub-folder. Modify the .jsproj and import the msbuild typescript targets.
Trigger remote debugging build in VS2015.

Result

2>Copying file "C:\Users\someuser\vsproject\projname\src\default.js" to layout "src/default.js"...
2>Error : DEP2100 : Cannot copy the file "C:\Users\someuser\vsproject\projname\src\default.js" to the target machine "192.168.2.4". 
2>Error : DEP2100 : Cannot copy the file "C:\Users\someuser\vsproject\projname\src\default.js" to the target machine "192.168.2.4". 
2>The system cannot find the path specified. (Exception from HRESULT: 0x80070003)
2>Deployment of the application to the target device failed.

Issue seems to be that the layout has path with forward slash which are not valid network paths in Windows. The path comes from Content Include defined in the typescript targets.

Workaround

Patch PreComputeCompileTypeScript target in C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v14.0\TypeScript\Microsoft.TypeScript.targets to replace forward slash with backslash

      <Output TaskParameter="GeneratedJavascript" ItemName="GeneratedJavascriptX" />
    </VsTsc>
    <ItemGroup>
      <GeneratedJavascript Include="@(GeneratedJavascriptX->'%(Identity)'->Replace('/', '\'))">
        <DestinationRelativePath>%(DestinationRelativePath).Replace('/', '\')</DestinationRelativePath>
      </GeneratedJavascript>
    </ItemGroup>
