Thx for the fast reply.
U were right, i wasnt using the right solution.
I tried then use the Balder.Core.Silverlight solution but i could not compile either...
Then i realise vs2008 converted the solution, but left some important files out....
I wiil now try to see if i can compile each project alone.
Can u tell me the precedence order for me to start compile the projects, i mean, which one is first and so on...
Im very interested in become a contributor to these project cause i really like Silverlight and 3D as always been my favourite poison...hehe
