你可以试试这种方式



转换解决方案文件来换行在.SLN文件中包含'＃Visual Studio 2010'到'＃Visual Studio 2012'

you can try this way

convert the solution file to change the line containing '# Visual Studio 2010' to '# Visual Studio 2012' in the .SLN file

如果在VS2012中打开VS2010项目，它将使用向导自动执行。



但是如果你打算升级.NET版本我建议你研究谷歌作为升级因项目而异。

If you open VS2010 project in VS2012 it will automatically do it using a wizard.

But if your planning to upgrade .NET version I suggest you Research in google as up-gradation varies from project to project.
