SharePoint---"The Web application at <url> could not be found" Issue

在vs中做SharePoint 2010开发或调试的时候，经常会碰到如下的错误：

“The Web application at http://test-sp2010/ could not be found. Verify that you have typed the URL correctly. If the URL should be serving existing content, the system administrator may need to add a new request URL mapping to the intended application. ”

 

一般这个错误可以通过以下三种方式解决：

• 以Administrator的身份运行vs

       

• 修改.net framework的版本为3.5，因为SharePoint 2010是建立在.net 3.5之上的

       

• 修改编译运行平台为AnyCPU或X64（默认的是X86）
