Convert Visual Studio 7.1 project to Visual Studio 9 project?

I have an Asp.Net project in Visual Studio 7.1 , Now when I open it in Visual Studio 2008 , I can't access to project f开发者_C百科iles :

_{(source: picfront.org)}

How can I open the project with VS2008 or VS2010 ?

Open the sln file with a simple text editor (make backup)

and search for your project that did not find, and correct the directory path.

You have probably a line like that... you need to fix the dir, saved it and open it again.

   Project("{XXXX-XXXXX-XXXX}") = "PECeShopSame", 
"Dir1\PECeShopSame\PECeShopSame.csproj", "{XXXX-XXXXX-XXXX}"

I see this is old post but I learned that you can also accomplish converting the .csproj file by browsing to the .csproj file and double-clicking on it. Visual Studio will open and offer to convert it for you - follow the wizard. As a final step in the wizard, it will prompt you to select the project in solution explorer and convert to web application.

I had situation where the files didn't appear in solution explorer after converting .csproj file therefore I couldn't select "convert to web application". I closed the (empty) solution then opened as web site (instead of project/solution) and all was well!
