async Task about clearscript HOT 2 CLOSED

Hi @flat-eric147,

Since I am porting a large amount of C# code to use the async/await paradigm, I cannot use await in the property setter. In some cases the setter might trigger loading an image from a web resource.

Unfortunately, in both C# and JavaScript, the expression foo.bar = baz always evaluates to baz. There's no way for a property setter to return a task or promise that tracks the operation of the setter itself, nor is there a way to override the assignment operator in a way that would allow it.

Therefore, as far as we can tell, there's no way to add nonblocking behavior to settable properties without affecting their callers – in either language – so the first step is to decide how exactly you want your settable properties to behave in your new async-aware, nonblocking codebase.

And how would I await a c# async method in CleacScript/V8?

The easiest way would be to enable automatic task-promise conversion via V8ScriptEngineFlags.EnableTaskPromiseConversion. That way you could simply await tasks in script code. Let us know if you need an example.

Good luck!
