C # 2008 Express: project type (.csproj) is not supported by this version of the application

Question

C # 2008 Express: project type (.csproj) is not supported by this version of the application

I tried to look at some CodePlex projects to try to understand how others are developing their applications. I am having trouble trying to open these projects in C # 2008 Express. When I open either a solution or csproj files, I come across this error message:

'Foo.csproj' cannot be opened because its project type (.csproj) is not supported by this version of the application.
To open it, use the version that supports this type of project.

This does not happen when I open projects that I created myself. External projects are even automatically converted since 2005, when they are in this format, but throttled when it tries to open the converted file.

Is this a limitation for Express releases, or can I do something to fix this?

I tried to do a Google search, but the results I found were less useful.

Thanks!

UPDATE:
@JaredPar asked for a specific project that I'm having difficulty with.
The notorious "straw that broke camels back" is called Continuum , but I also ran into difficulties with other projects in CodePlex and also with the source Paint.NET.

I tried uninstalling and reinstalling, but the problem persists.
