Hello.

I'm using WPF RoslynCodeEditor control on .NET Framework 4.7.

Occasionally exceptions occur during code creation using RoslynCodeEditor.

This is Error Message.

System.InvalidOperationException: TextDocument can be accessed only from the thread that owns it.

When looking at the fourth and fifth lines, it seems that there is an error in Roslyn Control.

RoslynPad is now released to v14.1. I'm also curious when will RoslynPad.Editor Nuget be updated?

Error occurs intermittently during Ctrl+D , Ctrl+F, and coding in RoslynCodeEditor. Therefore, it is not easy to reproduce the error :(

The following is another error message I found.

If these errors are bugs, when will they be corrected?

@jiyeongj Unfortunately I don't have the resources to look into them right now. That's why I added the "help wanted" tag.

Then I have a question.
I added the following method to use the Crtl+D key in RoslynCodeEditor:

private async void _formatDocumentAction()
		{
			_roslynItem = Documents[0];
			var document = _roslynItem.Host.GetDocument(_roslynItem.DocumentId);
			var formattedDocument = await Formatter.FormatAsync(document).ConfigureAwait(false);
			_roslynItem.Host.UpdateDocument(formattedDocument);
		}

Is the ConfigureAwait(false) causing a thread-related error in this method?

It's possible. Should probably use Dispatcher.CheckAccess and if necessary dispatch the avalonEditTextContainer.UpdateText call in RoslynCodeEditor.

Thx :)
I'll give it a try.
