How to make partial method async

Question

I have a generated code with partial method

{
    ...
    partial void InterceptOperationCall(IOperationContext context);
    ...

    async Task SomeMethod()
    {
        InterceptOperationCall(cntx);
        await LongOperation(cntx);
    }
}

and handwrited partial

{
    partial void InterceptOperationCall(IOperationContext context)
    {
    }
}

I need to do async calls inside InterceptOperationCall Does any one knows some way to workaround partial method restrictions?

Another words: I want to do InterceptOperationCall asynchronously and guaranteed before long operation, at the same time i want to optionaly declare body of this method in another file.

UPD as workaround solution i chose to:

• not use generated partial method stubs, and wrap with dynamic proxy (Castle.DynamicProxy) and intercept with AsyncInterceptorBase from (Nito.AsyncEx)
• another option I see rewrite codegenerator

Any way I keep looking for better solution, and if someone know another ways to provide optional ability to wrap async calls with somoe async logic please help me.

Answer 1

You can use the async keyword when implementing the partial method.

So

async partial void InterceptOperationCall(IOperationContext context) {

}

should be no problem.
