.NET Dispatcher, for .NET Core?

Question

Does something like Dispatcher exist for .NET Core?

I need to create a thread in .NET Core, and be able to send actions to be invoked on the thread. Also, I'd like to be able to use a TaskScheduler that can be used for async/await stuff.

Does this exist somewhere?

It's not built-in, but my AsyncContext and AsyncContextThread types are available in a library that would fit your need.

AsyncContext takes over the current thread:

AsyncContext.Run(async () =>
{
  ... // any awaits in here resume on the same thread.
});
// `Run` blocks until all async work is done.

AsyncContextThread is a separate thread with its own AsyncContext:

using (var thread = new AsyncContextThread())
{
  // Queue work to the thread.
  thread.Factory.Run(async () =>
  {
    ... // any awaits in here resume on the same thread.
  });
  await thread.JoinAsync(); // or `thread.Join();`
}

AsyncContext provides a SynchronizationContext as well as a TaskScheduler/TaskFactory.
