CRR0033 - The void async method should be in a try/catch block
This analyzer detects asynchronous methods that returns nothing and does not catch the inner exceptions.
async void DemoMethodAsync(CancellationToken token) {
await Task.Run(() => { DemoMethodSync(); }, token).ConfigureAwait(false);
}
Async Sub DemoMethodAsync(token As CancellationToken)
Await Task.Run(Sub() DemoMethodSync(), token).ConfigureAwait(False)
End Sub
The shown code can cause the app to crash because the exceptions thrown within a void async method cannot be caught from the outside — you should always catch them inside the method.
async void DemoMethodAsync(CancellationToken token) {
try {
await Task.Run(() => { DemoMethodSync(); }, token).ConfigureAwait(false);
} catch(Exception ex) {
Console.WriteLine(ex);
}
}
Async Sub DemoMethodAsync(token As CancellationToken)
Try
Await Task.Run(Sub() DemoMethodSync(), token).ConfigureAwait(False)
Catch ex As Exception
Console.WriteLine(ex)
End Try
End Sub
