I am getting warning from main thread.
Member ✭✭
I have many apis calls in a single page. The approach i am currently using is start a await Task.Run(() thread, do fetch operation, start Main Thread and do UI operations. The app works smooth but after few navigation, it stops responding. With some research it found thus can be due to main thread. Is this the correct way implementation, that i am using?
await Task.Run(() =>
{
fetchdata();
fetchData2();
fetchData3();
MainThread.BeginInvokeOnMainThread(() =>
{
//UI changes
}:
});

Why not simply use
Device.BeginInvokeOnMainThread?Post the content of fetchdata(), fetchData2() and fetchData3()
Post an example of a "UI change"
Do you start a new Task each time you navigate? Do you ever stop the Tasks, or do you end up with multiple Tasks doing the same thing?

What exactly do you mean by "UI changes"? Are you using bindings to display your data?
