I just had to convert a Visual Studio 2008 Solution and Project to Visual Studio 2005, because we had to exchange sources with somebody who did not use VS 2008 yet.
Even though Microsoft (of course ) did not provide a wizard or automated tool for it, converting the solution is possible to do, if you know what you are doing. It is actually pretty straight forward. At least in my case... I really can't tell if it is always that easy.
All I had to do in the .sln file:
change
PLAIN TEXT
XML:
Microsoft Visual Studio Solution File, Format Version 10.00
Microsoft Visual Studio Solution File, Format Version 10.00
to
PLAIN TEXT
XML:
Microsoft Visual Studio Solution File, Format Version 9.00
Microsoft Visual Studio Solution File, Format Version 9.00
The .csproj is more complicated (showing changes as diff):
PLAIN TEXT
XML:
