从.NET 3.5项目中引用时，作为.NET 3.5构建的clr DLL“需要更高版本”。

Question

I built the dll using Visual Studio 2008 for .NET 3.5 targeted framework.

Loading it into a .NET project built in 3.5 gives the error

"OpenGLControl.dll", or one of its dependencies, requires a later version of the .NET Framework.... etc.

The dll shows a 'runtime version' of v2.0.50727.

Anyone experienced something similar? Any solutions?

According to this site: that should be acceptable for a .NET 3.5 build.

Thanks!

In the end the issue was an unversioned dependency, although not listed as a higher framework version it seems VS2008 'assumed' it to be higher. So not only must the dependencies by the same version or less, they must all have an explicit framework version.
