After upgrade of Visual Studio 2017 last week on my build server, the MS Build 15.0 is not in use anymore. So whenever I try to compile visual studio 2017 projects which use new feature they will fail.
The Warning in build log is:
Visual Studio version '15.0' not found. Looking for the latest version.
And the error is:
something.cs(542,41): Error CS1525: Invalid expression term 'int'
Which is because build server is using MS build 14.0 I guess.
So far I have 1- Uninstall and Reinstalled the Visual Studio 2017 on the build server. 2- Installed "Visual Studio Build Tools 2017".
And nothing works. I have read some articles and apparently there are missing registry values but I don't know how to create them.
Appreciate your helps on this topic.
I am using TFS 2017 SP1 (On premises) and Visual Studio 2017 latest updates.
I have resolved this issue by upgrading my TFS from TFS 2017 SP1 to TFS 2017 SP2.
Thanks to @Patrick-MSFT and @Martin Ullrich for your help.
