将C＃项目从Visual Studio 2010降级到Visual Studio 2008

Question

我编写了一个Visual C＃2008 Windows窗体应用程序，然后在装有Visual Studio 2010的计算机中编辑了代码，但是我无法再在Visual 2008中运行它，有没有办法做到这一点？

Answer 1

When you say "can no longer run it"... what happens?

• the sln files are not compatible; you'll need different sln files for each VS version
• the csproj are mostly compatible, although you might see a "version 4 not recognised, using 3.5 instead" warning or two, which is usually fine
• the cs is compatible as long as you don't use dynamic or the other new language features

In most cases you can get away with just having a separate sln for VS2010. So just rename it to "Whatever_2010.sln", get your old "Whatever.sln" back from your source repository, and rename it to "Whatever_2008.sln".
