First off, what do these translate to?

resolveResult!: (v: any) => void;
    rejectResult!: (e: Error) => void;

I think this should be similar to defining

Func<object, void> resolveResult

Very close, it's

Action<object>

.

Ah, sorry 🙂 Been a while since I’ve done much C#

Next question:

resolveResult

&

rejectResult

(seen here) are just declarations, right? Where are they initialized?

that chunk you linked does initialize

resolveResult

and

rejectResult

(the promise constructor runs the executor immediately https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise/Promise#Parameters) The goal of linking these properties from the

LanguageServer.result

property was to make it easy for other downstream consumers to interact with language server. In practice we don't really use the exposed promise and handle the lifetime a little more manually. I would not feel constrained by this for the dotnet implementation, it's really just to make callbacks easier to manage in javascript.

I’m not sure about the context but TaskCompletionSource sounds the closest to the resolve/reject pair?
