Initialize Func<T1,T2> as an extension method
c#, extension-methods, lambda
Solution
Short answer: no, thats not possible.
Extension methods are syntactic sugar and can only be defined under certain circumstances (static method inside a static class). There is no equivalent of this with lambda functions.
Problem
Is it possible to make a Func delegate an extension method? For example, just like you could create the function ``` bool isSet(this string x) {return x.Length > 0;} ``` I'd like to be able to write something like ``` Func<string, bool> isSet = (this x => x.Length > 0); ``` Of course, the above is not syntactically correct. Is there anything that is? If not, is that a limitation in syntax or compilation?
