We are getting the same error. We have two syncfusion projects in Visual Studio. One is VS 2008 and needs to use the .NET 3.5 and the other in VS 2012 and needs to use .NET 4.0. How can we get both to work on the same development machine? Setting the .NET framework in Multi-Target Manager has no effect. The only thing that works right now is removing the .net 3.5 or 4.0 assemblies in the Assembly Manager to get the respective project to work. Is there an easier way?
Thanks,
Adam
