c# - Wait without blocking for event to fire -

this question exact duplicate of:

edit: no, question has not been answered in post linked above.

if have pseudocode:

// stuff first wait until classname.eventname fires without blocking // rest of code

is there way of doing in c# .net 4.0 ?

edit:

i have downloaded async targetting pack , trying that. (my project targetting .net 4.0.)

i've added code now.

private static async void waitasyncnoblock() {     await dynmapservlayer.isinitialized;                  }

so called this.

// stuff first waitasyncnoblock(); // more stuff

but error message, "cannot await bool."

if talking using await in code can in .net 4.5 can use async targeting pack microsoft add functionality .net 4.0 programs.
