[jbe2277]

• .NET Core SDK: 3.0.100-preview5-011256 [e6f157e5a4]
• Microsoft.WindowsDesktop.App 3.0.0-preview5-27610-56
• VS 2019: 16.1.0 Preview 1.0
• Windows version: Win10 1809 (Azure VM, connected via Remote Desktop)

• Open System.Waf.sln in VS 2019.
• Set Samples/Writer/Writer.Presentation as start-up project
• Start the application and click on New.
• Click on Ribbon menu and then on Print preview.

Expected: The Print preview should be shown. You could compare this with the master branch (targets .NET 4.6.1)

Actual: The exception System.Windows.Markup.XamlParseException: 'Add value to collection of type 'System.Windows.Documents.DocumentReferenceCollection' threw an exception.' Line number '1' and line position '136'. ---> System.UriFormatException: Invalid URI: The format of the URI could not be determined. is thrown.

Details:
The line FixedDocumentSequence documentSequence = xpsDocument.GetFixedDocumentSequence(); results in the following exception:

@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

[jbartlau]

@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.

[weltkante]

@jbartlau definitely a different issue, the non-seekable package streams are a known issue (#585) but your particular scenario wasn't mentioned anywhere yet, probably a good idea to add some details there so it doesn't get missed

[jbartlau]

@weltkante Thanks, done.

[stevenbrix]

@jbartlau thanks for letting us know! We'll continue the discussion on #585
