推荐答案

当您打开使用旧版Visual Studio 2010版创建的解决方案或项目时，您将可以通过解决方案/项目转换器运行，该转换器只会自动修改解决方案和项目文件.

由于生成的结果，由于过时的类型/成员，您可能会收到一些警告.

由于2008年之前的Visual Studio不是多目标的，因此您可能需要将目标Framework更改为v.4.0.您可以选择任何目标Framework版本，因为它们是向后兼容的.针对2.0的解决方案可以在Framework 4.0或3.5中轻松运行.

When you open a solution or a project created with older versions of Visual Studio with version 2010, you will be offered to run through solution/project converter which will only modify solution and project files, automatically.

As a result of a build you may get some warning due to obsolete types/members.

As Visual Studio prior to 2008 was not multi-target, you may need to change the target Framework to v.4.0. You can select any the target Framework version, they are backward-compatible. The solution targeted for 2.0 will be readily run in the Framework 4.0 or 3.5.

只需在项目属性中将目标框架从2.0更改为4.0.

Just change the Target Framework from 2.0 to 4.0 in the Project Properties.
