XpsDocument.GetFixedDocumentSequence throws NotSupportedException

[elyoh]

• NET Core Version: 3.0.0-preview6-27804-01 (also in preview 5).
• Windows version: Win10
• Does the bug reproduce also in WPF for .NET Framework 4.8?: No

An attempt is made to read an XPS document from disk:

var doc = new XpsDocument("path to file", FileAccess.Read);
var seq = doc.GetFixedDocumentSequence();

The following exception is thrown:

System.Windows.Markup.XamlParseException: ''Initialization of 'System.Windows.Documents.FixedDocument' threw an exception.' Line number '1' and line position '479'.'

Inner exception:

NotSupportedException: Specified method is not supported.

Stack trace:

This appears to be a different issue to #575.

This was already mentioned in the comments of #575, your scenario is probably caused by #585 but you'd have to check the inner exception to know for sure.

That looks different from what I'd expect for #585 so probably needs a separate investigation.

@elyoh This seems like something specific to the XPS being displayed or something that has been fixed in Preview8.

I tested this against several XPS documents sitting around in our test code and I was able to display them all without an error on 3.0.100-preview8-013275.

Can you test against the latest daily build and, if this still reproduces, supply an XPS document that causes the issue to occur?

[rladuca]

#585 (comment) seems to actually have a similar stack in Preview 8. Using the document from that repro, I get:

@stevenbrix @vatsan-madhavan We should sync up on what we know from #585.

CC: @jbartlau since I used your reproduction document to mirror the same failure here.

This looks like our initialization of TypeFaces is directly calling into an unsupported part of the new zip implementation.

Take a look at this stack:

I have a feeling this is going to affect any XPS with local font resources. That's a pretty basic feature of XPS documents that won't work if we don't figure out some way around this.

@elyoh does your XPS document contain fonts?

[rladuca]

DeflateStream has this code:

        public override long Position
        {
            get { throw new NotSupportedException(SR.NotSupported); }
            set { throw new NotSupportedException(SR.NotSupported); }
        }
