Use An Extension Method Instead Of Just Creating Non-extension Sub Or Function?
Dec 3, 2009Why would I use an extension method instead of just creating non-extension sub or function?

Other than having the extension show up in Intellisense, is there any advantage? Is a call to the extension quicker/more efficient than a call to a regular function?
