if-statement: Does C# short circuit evaluation of if statement with await

jeudi 10 septembre 2020

I believe that C# stops evaluating an if-statement condition as soon as it is able to tell the outcome. So for example

if ( (1 < 0) && check_something_else() )
    // this will not be called

since the condition (1 < 0) evaluates as false the && condition cannot be met and check_something_else() will not be called.

How does C# evaluate an if statement with asynchronous functions? Does it wait for both to return? So for example

if( await first_check() && await second_check() )
    // ???

Will this ever be short-circuited?
