Managed callback to native code (reverse p/invoke)
Okay I asked a LLM and it says this: "When you pass a managed delegate to native code via P/Invoke, the CLR automatically generates a thunk (a small, fixed bridge between native and managed code). This thunk has a fixed address in memory, even if the delegate or its target object (ManagedClass) is moved by the GC." Is this true?

Yeah I found out the garbage collection part the hard way lol. Can you provide more info on why it doesn't have to be pinned? Couldn't the memory address change if not pinned?

Yeah that's what I'm thinking too, but wanted to get confirmation

Managed callback to native code (reverse p/invoke)
For example, I could have an unmanaged and managed representation of a class and have an instance id to track it between creation and disposal on the native side

Yeah I could, but I'm curious specifically about the semantics of an instanced callback.

Would this AsyncQueue have issues with multiple producers and a single consumer?
Yeah I realized that, I added a CancellationToken to DequeueAsync.

Yeah I saw some too, that is what made me ask honestly. No worries!

True, I guess that would be a weird situation anyways. Thanks for the reassurance. Much appreciated!

Yeah that is what I thought, I think there are no issues. I think it would only be a problem if there were multiple consumers since I think the semaphore and dequeue operation could get out of sync

How can I reference multiple generics in summary?
Yeah I left it off there by mistake, I was just showing the documentation portion. That is a good point though

Yeah, you're right. It just shows the summary all in white.

This might be slightly better because the links actually go to the right type, however the types lose the the appropriate highlighting and just appear blue. 
/// <summary>
/// </summary>
/// <typeparam name="T"></typeparam>
/// <returns>
/// A <see cref="Task{_}">Task</see>&lt;<see cref="Handle{_}">Handle</see>&lt;<typeparamref name="T"/>&gt;&gt;
/// </returns>
public Task<Handle<T>> Foo<T>()
{
    return default;
}

So this is definitely a hack, as it requires a non generic type to exist and it obviously links to that non generic type if clicked on. This at least gets the highlighting correct though in the summary when hovering over the method in Visual Studio. 
/// <summary>
/// You can access the Result from the <see cref="AsyncOperationHandle"/>&lt;<typeparamref name="T"/>&gt; after awaiting assuming the load did not fail.
/// </summary>
/// <returns>
/// An awaitable <see cref="UniTask"/>&lt;<see cref="AsyncOperationHandle"/>&lt;<typeparamref name="T"/>&gt;&gt; instead of <see cref="UniTask"/>&lt;<typeparamref name="T"/>&gt; 
/// because as the caller you are responsible for releasing the handle when appropriate.
/// </returns>
public static async UniTask<AsyncOperationHandle<T>> LoadAssetAsync<T>(object key)
{
}
