3DTools.dll added in reference, _3DTools namespace and assembly (3DTools) is added in xaml, _3DTool added as using, project is built in Visual Studio 2008 Team System and operating system is Vista. The code gets compiled and it runs without error but the design window does not show and error is the 3DTools assembly is not found and _3DTools too. I tried a lot but failed to get it fixed. Hope someone may help me to fix it.
