Can .NET 4.0 code interoperate with .NET 2.0 code?

Question

Are there compatibility barriers with a .NET 4.0 assembly calling code in a .NET 2.0 assembly? And vice versa?

More specifically, I\'m investigating an upgrade to Visua

Answer 1

.NET 4.0 assemblies can call .NET 2.0 assemblies with no difficulty. However, it is highly unlikely you will be able to call a .NET 4.0 assembly from .NET 2.0 unless the .NET 4.0 assembly did not take advantage of any new framework features and you setup assembly redirects.
