Hello,
We managed to reproduce the issue with the designer without our controls. Any custom Window
descendant shows the same result.
We recommend contacting Microsoft support to resolve this issue.
Boris, let's continue our discussion about this exception in your original ticket.
Hello,
It turns out that Visual Studio opens
.xaml
files in the XML file editor. You can use context menu as a workaround:Hi Dima,
This leads to the initial issue I reported, having this error as a result:
I will repeat it here as well - it does not happen with xaml without DevExpress controls in it.
My environment is VS 2022 v17.6.0 and DevExpress 22.2.6.
Please consider this ticket to be urgent, as our development process is significantly slower without being able to use the designer.
It looks like, that only when the root element is a DevExpress control, the XAML Designer doesn't works as expected. If any child elements are DevExpress controls, everything works well.
