What's the difference between Type.IsSubclassOf and TypeInfo.GetSubclassOf?

I just noticed there are two methods to check if a class is derived from another class:

• The 'old' method which exists since .NET framework 1.1 : Type.IsSubclassOf(Type)
• A 'new' method which exists only since .NET framework 4.5 : TypeInfo.IsSubclassOf

Is there any reason this newer method was created? From what I see they both do the same.
