I'm still trying to learn the VSIX stuff - and I'm still doing in process extensions (since I think out of process extension are still in preview).
But I am trying to show a Dialog in a Visual Studio extension and I get this error:
System.Windows.Markup.XamlParseException
HResult=0x80131501
Message='Initialization of 'VSIXProject13.MyCustomDialog' threw an exception.' Line number '19' and line position '7'.

I have searched google and everything else and found nothing relevant. This dialog I have now is completely "empty" , this was done to narrow down the issue. But even the empty dialog I still get this error:

Hello, how did you define and reference the ResourceDictionary?
You can try to define the resource by adding the full path of Source:
<ResourceDictionary Source="pack://application:,,,/MySolution.MyProject;component/themes/themeresources.xaml" />
And ensure the xaml Build Action is set to Page.
Thank you very much for your answer but unfortantely I am more a Winforms, Webforms and lately kind of Blazer Server person :-)
I'm not sure where the resource mark up would go in my project - I assume in the XAML for the component?
Which I tried but I'm not sure of the syntax for the location. Here is my current directory structure:
There is also no .xaml resource file present in the solution that I can find. It could be under one of the nuget packages? But I even tried looking at those and I am not seeing it - yet - but I am still looking. I know the nuget packages are essentially zip files.
The dialog component was added like this:
I would have that that would have added any resource files that were necessary. I can get the dialog to show if I use this:
Which is fine for now, it's going to be an internal tool for our team. However, I would eventually like to figure out this issue.
Thanks
Jim
Hi Anna,
Thanks for very much for the information, I will give a try after work today!
Jim

Hi @Jim Locigno ,
It may be related to the Community.VisualStudio.Toolkit.
You can try to update the NuGet package to the latest version 17.0.507. You can see the similar issue:
