How to make Visual Studio 2010 recognize file extensions as C#/ASPX/C/C++ files?

Question

There was a solution for VS 2005 here:

But doesn't find same registry for VS2008 and VS2010. So where can I find the solution update for this ? Thanks.

如果您要查找的是VS 2010编辑器中不同扩展名的语法高亮显示：转到工具 - >选项 - > TextEditor - >文件扩展名并输入扩展名。

I don't think it is any different. You however have to change the version number in the registry key name HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\VisualStudio\\8.0\\Languages\\File Extensions. VS2008 is 9.0, VS2010 is 10.0

These kind of registry hacks don't scale very well. It stops working when you open the project on another machine or use a different VS version. As you found out. Just renaming the file is the much lower pain-point.
