我正在使用dot net framework（4.0）visual studio 2010。我的一个朋友给了我他在.net framework 4.5（vs 2012）中开发的项目。我无法打开项目

。我得到的错误是无法读取项目文件'EssentialTools.Tests.csproj'。

VS 2012解决方案无法在VS 2010中直接打开。一种方法是在VS2010中创建新项目并将代码文件复制到其中。否则，您需要对VS 2012解决方案进行以下更改：



1.打开Sln文件并更改格式版本到11.00。

2.在app.config文件中，将框架版本更改为4.0。

3.将项目文件中的目标框架更改为4.0。

VS 2012 solutions cannot be directly opened in VS 2010. One way would be create new project in VS2010 and copy code files to it. Or else, you will need to make following changes to VS 2012 solution:

1. Open Sln file and change Format Version to 11.00.
2. In app.config file, change framework version to 4.0.
3. Change target framework in project file to 4.0.
