Many weeks of research and testing later, I find myself in a "dead end" regarding Team Services. I have a Solution with project in ASP.NET Webforms in Team Foundation of VSTS. For operational reasons, I am putting together a methodology to automatically version the code via the Build & Release that is available in VSTS. However, my project should always be precompiled (aspx.cs and / AppCode compiled into a single assembly). The compile options via "MSBuild.exe" and "Publish Artifact" always give me an Artifact without the precompile, regardless of the settings I change in Solution's .sln or the configuration parameters I pass to MSBuild. I'm compiling in Release, and in the .sln settings I've pointed to Updatable = false, but nothing worked so far. Is there any way to actually build pre-compiled VSTS Builds for asp.NET Webforms Solutions?
