1) Software Center >> MonoDevelop >> Install
2) MonoDevelop >> File >> New Solution >> Gtk# 2.0 Project (C# or VB doesn't matter)
3) Start Debugging >> Build error: The imported project "/.cache/MonoDevelop/7.0/MSBuild/2065_1/Microsoft.*.Core.targets" was not found.
Such files (Microsoft.CSharp.Core.targets and Microsoft.VisualBasic.Core.targets) do exist one folder deeper on the given path under 'Roslyn' sudfolder.
What's the correct way to fix this?
