.NET Port

Same question as #26 but for .NET.

The key consideration is that you need a way to capture the calls to data loader during a single stack frame of execution.

There are two ways to do this:

1. Your target environment has an event loop and you schedule the "dispatch" of a dataloader batch to occur after the current "tick" of the event loop.

2. Your target environment has a stack of calls and you schedule the "dispatch" of a dataloader batch to occur when the current call stack has unwound.

This dataloader library for JavaScript actually uses approach 2) via the Promises "micro task queue" - which is a queue of operations to perform that begins empty at each call stack and is executed when the call stack unwinds. However if we had built this library before native Promises (or via using a Promise "polyfill") we use approach 1) where we enqueue work on the event loop (i.e. setTimeout).

Most, but not all, environments have an event loop - so the event loop approach is usually a good one. Nearly all environments have a call stack. If the native call stack does not support an "on unwind" task queue (likely) then a suitable substitute is to create a base function which you use everywhere a call stack could be created: in your program's main, in a custom version of Future so it can wrap completion callbacks, etc.
