// With identity conversions you may have generic variance in mind, however, this is not possible due to 
// Identity conversions are mostly important for tuples when it comes to constructed types. If you could easily convert from (int, int) to (int x, int y) but not from IEnumerable<(int, int)> to IEnumerable(<int x, int y>) you would be quite annoyed.

//Although you can ignore some preceding information and ignore what the CLR does with tuples, you'll be able to do more with tuples and better understand the behavior.
//Unlike anonymous types, in which unique sequence of property names within an assembly causes the compiler to generate a new type, typles don't require any extra types to be generated by the compiler. Instead, it uses a new set of types from the framework.

//Tuples in C# 7are implemented using the System.ValueTuple. A description of any type of is very much like the description of tuple types from earlier: it's a value type with public fields. You might expect the ValueTuple to be static - i

If you're used to function pointers in C, a delegate is basically a pair of pointers rolled into one:

    A pointer to an object (optional)
    A pointer to a method of that object

That means a single delegate passes all the information needed to locate a function in your program, whether it's a static method or associated with an object.

You define them like this in C#:

public delegate void FooCallbackType( int a, int b, int c );
