naming conventions - Is there a meaningful difference between "Double" and "double" in .Net?

Question

As regards best practices, is there a meaningful difference between using:

Double d;

and

double d;

I know best practices are fraught with contradictions, so I know the answers may vary here. I just want to know the pragmatic difference between the two.

Answer 1

There is no difference. double is just an alias for System.Double in C#.

Note that VB.NET doesn't have the same aliasing (int for System.Int32, double for System.Double, etc), so the aliasing is just applicable to C#, not .NET as a whole.
