c# wpf keep ui response not working (c# thread )
https://docs.microsoft.com/en-us/windows/uwp/debug-test-perf/keep-the-ui-thread-responsive
Above url says that don't put UI things with main working function.
// Perform background work here. // Don't directly access UI elements from this method.
The key point is let sub function be called inside:
await Task.Run(() => 'your function working long');
If you mix up main thread and ui thread, below error happens.
the calling thread cannot access this object

Read related article thoroughly:

Below code will not work for showing spinner
uiBefore();
ConnectionChanged();
uiAfter();
Below code works
uiBefore();
await Task.Run(() =>
{
ConnectionChanged();
});
uiAfter();
private void uiBefore()
{
faSpinner.Visibility = Visibility.Visible;
}
private void uiAfter()
{
faSpinner.Visibility = Visibility.Collapsed;
}
It seems funciton inside await Task.Run() doesn't have to be async function. Only the parent function needs to be async. Below code works.
