I haven't looked at whether dotnet20 also needs the font kludges...
Oh, ok, I fixed dotnet20, too. And wsh56 no longer requires you to run vcrun6 first (it does it for you).
Note: dotnet11 and dotnet20 may crash on startup if you have msttcorefonts installed outside of Wine! (That's because corefonts does nothing if you already have those fonts installed on the base Linux system; the font installers just go "Oh, he already has this? Shrug." This is kind of nasty; people shouldn't have to uninstall msttcorefonts to run winetricks. But I don't have a good fix for it yet.)
