Visual Studio unable to open Web site error

Question

I work with Visual Studio 2008 and work on a web project which contains a web site. When opening the solution file, I receive the error message:

Unable to open the Web site http://localhost/myWebsite.de. The Web site http://localhost/myWebsite.de does not exist.

I can see the web site greyed out, with the remark "unavailable", in the solution folder.

It is possible to add the web site to the solution, but after relaunching Visual Studio, it´s gone again.

Has anyone had this problem in a similar way?

Answer 1

Open the existing Solution file using notepad, Copy the actual project Directory path and update the solution file content with respect to following options alone

Debug.AspNetCompiler.PhysicalPath = "update the path here"
Release.AspNetCompiler.PhysicalPath = "update the path here"
SlnRelativePath = "update the path here"

leave the remaining config untouched
