promise

Introduction

Instead of using .NET's Task Parallel Library, I'll be using my own custom class to represent asynchronous operation. It's all wrapped in the Promise and PromiseResult<> classes. If you know how to use .NET's Task and Task<> classes, it is the same.

Why?

For performance reasons and for simplicity. Promise is lighter and simpler. When a scheduled event is needed, it will be automatically dispatched to the server's scheduler thread. Once it expires, it will automatically dispatch all the actions to the main server's (single thread) dispatcher thread. We don't want to deal with concurrency problems, do we?

How to use

//...

Promise.Delay("CancellationKey", TimeSpan.FromSeconds(10) ).Then( () =>
{
	//...

	return Promise.Completed;
} );

or

public async Promise SomeMethod()
{
	//...

	await Promise.Delay("CancellationKey", TimeSpan.FromSeconds(10) );

	//...
}
