The scope of my question is solely ASP.NET, as the answer may be different for Java and any other C based language.
How much overhead is involved when using the keyword "this" within a class to dereference a property? It seems that I've seen certain sources try to discourage the use of "this" for dereferencing, but generaly I've just ignored them until now.
StyleCop recommended using this for all instance field reference.
And when compared to access the said field through a property, shouldn't it actually be faster (albeit unnoticable) by bypassing abstraction?
I think it is just a style issue. As stated in the answer to this question, the compiler injects 'this' into implicit uses of this. I would use it for clarity.
