✅ is there any way to cast Task into Task<object>?

so, i have this delegate function:

public delegate object RouterCallback(HttpRequest request);

public delegate object RouterCallback(HttpRequest request);

which some methods already implements it, and some of then are async that returns

Task<something>

Task<something>

, and i need that value inside that task.

for non Task<T> methods i can have it using:

object actionResult = matchedRoute.Callback(request);

object actionResult = matchedRoute.Callback(request);

and fine, but if it is

Task<something>

Task<something>

i can only determine if it is an task using:

if (actionResult is Task taskResult)

if (actionResult is Task taskResult)

but it doens't has the

.Result

.Result

property since it's an

Task

Task

and not

Task<T>

Task<T>

i can unsafely cast it and get it result using

 if (actionResult is Task asyncResult)
 {
     asyncResult.Wait();

     var valueTask = Unsafe.As<Task<object>>(asyncResult);
     actionResult = valueTask.Result;
     // do something with actionResult
}

 if (actionResult is Task asyncResult)
 {
     asyncResult.Wait();

     var valueTask = Unsafe.As<Task<object>>(asyncResult);
     actionResult = valueTask.Result;
     // do something with actionResult
}

but it only works when

is an reference-type and doens't works when

is an struct/value type object.

so, I need to get the value of

Task<T> actionResult

Task<T> actionResult

when actionResult is a

Task<T>

Task<T>

, but I don't know what
