Hello Wilhelm,
Regarding VS2010 and .NET 4.0, it is a company policy to have installations only for officially released versions of VS and the .NET framework. However, we have tested the controls with VS2010 Beta 2 and RC, they are working fine. The .NET 4.0 RC (Beta) is giving problems and we are waiting for the official release. Compiling with .NET 3.5 works correctly.
Once VS2010 and the .NET 4.0 are officially released, it will take no more than a week for the official installation of Nevron .NET Vision for VS2010.
Please let us know if you have any questions and forward all issues you meet with the VS2010 evaluation.
Best Regards,Nevron Support Team
