I tried to compile the AspNetControl extension, but it appears to include C# 6 (or 7??) features, which my VS2013 cannot compile. It would be useful to have also the binaries in the Extensions page, at least until the extensions are included in the release.
Sorry about that. Will add. You can also install the latest Microsoft compilers for VS2013 here: https://www.nuget.org/packages/Microsoft.Net.Compilers/
You’ll get the syntax errors in the editor only but the compiler will work since it’s the same as in VS2015.
