After switching from VS 2015 to 2017 i started having issued while building projects that contain WorkflowFundation files (xaml).
Error:
NCrunch: If you are experiencing problems in getting this project to build, have a look at http://www.ncrunch.net/documentation/troubleshooting_project-build-issues
C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\Microsoft.Xaml.targets: XC1020: Build error occurred in the XAML MSBuild task: 'Could not load file or assembly 'XamlBuildTask, Version=15.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.'
Repro :
Create test project with workflow foundation files and there you are, it fails to build.
Additional info:
If Xaml files are removed the project builds correctly. It works w/o problems in 2015.
I checked that XamlBuildTask.dll is available in the "C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\" but what looks suspicious to me is that the version it searches for "Version=15.0.0.0". That version of the file does no exist and probably shouldn't.
Thanks
