how to use Asynchronous delegates on a void return method

Question

i want to make a method async

i was trying to do the following

Func method = PrepareData<T>;
method.invoke
...

but it complain Func must specify something e,g Func

so my question is, how to make a void return method asyn??

You should use Action instead of Func. The Action family is for functions with a void return type, Func is for those that actually return something.
