Do you execute an empty query? Lines with '#' are the comments.

The error appears from the starting page (Just run the code then this page is appeared).

Below is with query.

Try the latest preview version of GraphQL package to see if problem persists.

After updated to 3.0.0-preview-1271. Can't compile the code.

Just change IDependencyResolver to IServiceProvider interface.
