The app is crashing when clicked the Teditor. This works flawlessly on Visual Studio 2017 and not on the 2019 version.
Is there any error or exception occured? What is the 'Teditor' control? Do you mean the TEditor nuget? I cretaed a basic demo to test the control, it works fine as below.
private async void Button_Clicked(object sender, EventArgs e)
{
TEditorResponse response = await CrossTEditor.Current.ShowTEditor("<p>XAM consulting</p>");
if (!string.IsNullOrEmpty(response.HTML))
browser.Source = new HtmlWebViewSource() { Html = response.HTML };
}
Try to empty the bin and obj folders of both the shared project and each platform project, then build the project again. If it still doesn't work, try to update the nuget packages to the lastest stable version and test.
