[jbe2277]

• .NET Core SDK: 3.0.100-preview5-011256 [e6f157e5a4]
• Microsoft.WindowsDesktop.App 3.0.0-preview5-27610-56

@jbe2277 can you confirm this is still happening in the latest preview? i just tried this out and it doesn't seem to repro with this SDK/runtime combo:

SDK: 3.0.100-preview6-012105
Microsoft.WindowsDesktop.App 3.0.0-preview6-27728-04

@stevenbrix I had a repro too, although it might be a different issue as the exception is of a different type. Glad to open separate issue then. I get a NotSupportedException when calling into GetFixedDocumentSequence, Exception details are

System.NotSupportedException
  HResult=0x80131515
  Message=This operation is not supported.

Tested on preview 6. Just let me know if I should open a separate issue for this. I'll then try to minimize my app.
