"Could not write lines to file "obj\Debug\MvvmCross.Platform.csproj.FileListAbsolute.txt". The process cannot access the file 'C:\Projects\MVVMCross\MvvmCross\Platform\Platform\obj\Debug\MvvmCross.Platform.csproj.FileListAbsolute.txt' because it is being used by another process."
This looks like a bug that was first raised in 2015 and reported to be fixed in Xamarin 4.0. My build has been running for over 30 mins. Obviously it is not going to come back.
What is the solution for this?
