I have seen Solutions created in Visual Studio 2008 cannot be opened in Visual Studio 2005 and tried workaround 1. Yet to try the workaround 2.
But as that link was bit old and out of desperation asking here: Is there any convertor available?
I dont have VS2008 yet and i wanted to open an opensource solution which was done in vs2008.
Guess i have to fiddle around or wait till the vs2008 is shipped.
I have a project that I work on in both VS 2005 and VS 2008. The trick is just to have to different solution files, and to make sure they stay in sync. Remember that projects keep track of their files, so the main thing solutions do is keep track of which projects they contain; pretty easy to keep in sync.
So just create a new blank solution in VS 2005, and then add each of your projects to it, one by one. Be sure to name the solutions appropriately. (I call mine ProjectName.sln and ProjectNameVs2008.sln.)
Which is a long way of saying you should try workaround #2.
