我从网上下载了一个项目，但我无法打开该项目。它说该项目与当前版本不兼容。
我使用了VS 2012桌面快递，2013年桌面快递和最新的2015年桌面快报版本，但无法打开它。我很困惑知道发生了什么事。
please note: The test project InstaSharp.Tests.csproj is opening.
InstaSharp.csproj is not opening.
错误消息：
src\InstaSharp\InstaSharp.csproj: The application which this project type is based on was not found. Please try this link for further information: http://go.microsoft.com/fwlink/?LinkID=299083&projecttype=786C830F-07A1-408B-BD7F-6EE04809D6DB
这是项目文件。它说vs2013，但当我尝试使用vs2013打开文件时，它根本就没有发生。
