//A Action is a container to set a method for invoking that has no returns 

//where as a Func is a container to set a method for invoking that has returns

//so

//Any Generals or Templates in a Action will always be signiture input params

//Where as to say a function will alway have a output return indicated by the

//last General or Template type and any others will be inputs params.

//Addtionally async invokers (.BeginInvoke) with actions can be fire and forget 

//where as a Funcs must be awaited for the result using the EndInvoke

//example using lambda's (Short handed anonymous methods):

//Actions

Action BasicAction = ()=>{/*does something*/};

Action</*in*/ Type> SingleParamiterizedAction = (x)=>{/*does something*/};

Action</*in*/ Type1, /*in*/ Type2> DoubleParamiterizedAction = (x, y)=>{/*does something*/};

//....

Func</*out*/ TResult> BasicFunc = ()=>{/*does something*/ return TheTResult; };

Func</*in*/ Type,/*out*/ TypeResult> SingleParamiterizedFunc = (x)=>{/*does something*/ return TheTypeResult; };

Func</*in*/ Type1, /*in*/ Type2, /*out*/ TypeResult> DoubleParamiterizedFunc = (x, y)=>{/*does something*/ return TheTypeResult; }

//Usage example

BasicAction.Invoke(); //result of void can not be used

TResult TheResult = BasicFunc(); // result of the methods output can be used.
