Is a ret instruction required in .NET applications?

I noticed that the C# compiler generates a ret instruction at the end of void methods:

.method private hidebysig static void Main(string[] args) cil managed
{
    // method body
    L_0030: ret 
} 

I've written a compiler for .NET and it works regardless if I emit a ret statement or not (I've checked the generated IL and it's indeed not in there).

I just wonder: Is ret on methods returning void required for anything? It doesn't seem to do anything with the stack, so I believe it's completely unnecessary for void methods, but I'd like to hear from someone who knows a bit more about the CLR?
