MsBuild, TFS and Visual Studio 2015

Hi,

I try to do a setup with TFS Build

When I do the setup in Visual Studio 2015, I have no errors but when I try with TFS I a reference error (No outputs for the project "..." were provided, but the installation project references "...".)

I added these lines to .isproj and everything works perfectly:

<ItemGroup>
<ProjectReference Include = ".... vbproj">
<Name> ... </ name>
<Project> .... </ Project>
</ ProjectReference>
</ ItemGroup>

But when I open my solution in Visual Studio, it automatically deletes these lines and the TFS build stopped working.

I use the project in Visual Studio to add "Primary Output" of my project

Thanks for your help
