In .NET is it faster to use the Attribute suffix even though it is not required?

Question

MSDN states that

you do not need to specify the attribute suffix when using attributes in code

Example: You have an attribute named HelpAttribute. You can decorate a property with [Help] (no Attribute suffix) or with [HelpAttribute]; either is allowable. But, does the code run faster when you use the full attribute name rather than the non-suffixed name?

Answer 1

There is no difference, its a syntax feature to save you typing Attribute all the time.

Answer 2

The code compiles down to the exact same IL and has 0 runtime performance difference.

Answer 3

it is a compiler feature, result IL will be the same
