I installed Shardevelop yesterday and I can't open any Android templates without getting this error message.
The imported project “C:\Dot42.CSharp.targets” was not found
The error message also tells me that there is a .csproj file in my project folder. However, I can't seem to find it.
I got around this issue by copying all the dot42.*.target files to the root of my c:\ drive from C:\Program Files\dot42\Android
