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