How do I default Visual Studio to C# projects instead of VB.NET?

Solution 1:

Tools -> Import and Export Settings -> Import Selected Environment Settings... -> Make selection whether to save current settings -> Select C# under the default setting folder

Solution 2:

Visual Studio (2008..and hopefuly '10 =x) defaults to whatever you chose as the last project's code language you created. Double check that yours isn't doing this >_< Try creating a new project in C# code, exit that project, and create another one and see what language it defaults to. If so, it will allow to keep your "Web Development Settings" rather that switch your main environment to C#, like the other solution suggests.
