I have a XAML file which I have pared down to find the cause of this issue to the following minimal case:
<FixedDocument
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" >
<PageContent>
</PageContent>
</FixedDocument>
It opens fine in a KAXAML, but when I open the same file in Expression Blend 4, I get the following 2 errors at the <PageContent>
tag:
There is no CodeBehind. The only interesting thing is that this file exists in a Winforms project, and I have applied the following hack: http://social.expression.microsoft.com/Forums/en-US/blend/thread/c726522f-c721-42a7-8bf1-c73360edaa60 - but the problem also happens with the file in a straight WPF project.
Does anyone know why, and have a fix for this?
This bug is as old as time and it doesn't appear it will be fixed any time soon:
Confirmed still to exist for both VS2010 and Expression Blend 4.
