Unable to resolve resolution root for TextDocumentSyncHandler from container without any scope.

[bobbytreed]

Good Morning,
I'm upgrading from .095 to the latest version of OmniSharp.

Everything was working fine in .095, but after upgrading, and changing my Program.cs file to look like your SampleServer File (for testing), I get the following error.

DryIoc.ContainerException: 'code: Error.UnableToResolveFromRegisteredServices;

                        )

In your example, I don't see anywhere that you are registering the TextDocumentHandler outside of the .With Statement.

Do you hany any ideas what could be missing here?

I just had the same problem after updating to 0.19.5...did you find out what was the problem?

[Skleni]

For me, it was caused by #338. I had some handlers with ILanguageServer constructor parameters. Changing these to ILanguageServerFacade fixed the issue.
