some problems with async await
hey guys before anything sorry for my bad english but here's my problems:
1. how can i add an item to a listbox in an async event method of a bindinglist's listchanged event.
2. whe i have one async method in my code there is no problems but when i have 2 or more async methods no matter wich one is running or one of them is running my app thows an exeption in delegate class and usually it's "parameter is not valid" and i have one guess and that is when in a try catch block some error happens it show me "parameter not valid" exeption in delegate class. i will be appreciated if you guys can help me
