Unless you're a .NET programmer, you should ignore this post. I'm entering it only as a small contribution to Google's search engine for the poor sap who, like me, is beset with the following error message when attempting to open a web project in Visual Studio.NET "Unable to get the project file from the web server". The solution? Delete everything in the c:\documents and settings\VSWebCache directory. I spent four hours spinning my wheels on this issue before finally finding a buried reference on an obscure message board. What a pain in the ass.
这个错误一般出在您复制一个项目然后再打开的时候，可是我是解压了Dasblog程序后打开项目时就出现这个问题了。
