can i call a .net 2.0 dll in .net 3.5?

Question

I am migrating to .net 3.5 and I want to know whether I can call from my 3.5 application, old .net 2.0 dll's methods?

Some external API's are in .net 2.0 dll. So I need those.

Kindly let me know. Thanks.

Answer 1

Yes. You can do that.

Answer 2

.NET 3.5 is nothing more than .NET 2.0 SP2 with some additional assemblies. This means that .NET 3.5 is .NET 2.0, to a large extent.

Answer 3

Yes, .NET remains compatible with old versions. There might be some obsolete code but it will still work. Only before 2.0 there can be compatibility issues.

Answer 4

Yes.
Genrally, you can run .Net 2.0 applications on a computer with newer versions of .Net, and using a DLL isn't different.

Answer 5

当然，两者都是托管代码soit应该像调用.net 3.5程序集一样工作。
