How to get types which implements specific interface from referenced nuget packages?

i try to find a way to get all classes which implements some interface and the location of these classes are referenced nuget packages. I know how to do it with referenced dll files by using Assembly.GetReferencedAssemblies. But how i can explore nuget packages? Is there some nuget which can help with this task?

Thank you!

I tried to look on PackageManager class but i didn't find what i want.
