#alias for

If Int32 is just an alias for int, how can the Int32 class use an int?

Been browsing through .NET source code of .NET Framework Reference Source, just for fun of it. And found something I don’t understand.

There is a Int32.cs file with C# code for Int32 type. And somehow that seems strange to me. How does the C# compiler compile code for Int32 type?

public struct Int32: IComparable, IFormattable, IConvertible { internal int m_value; // ... }

But isn’t…
