Hello,I am experiencing an issue related to the generic.shared.xaml file.
If I use this file I am not able to use the designer view of a WPF usercontrol since I get the following error.
I use a dirty trick when I need to change the layout, I comment the line referring to that file:
<Application.Resources> <ResourceDictionary> <ResourceDictionary.MergedDictionaries> <ResourceDictionary Source="/Assets/ApplicationStyles.xaml"/> <!--<ResourceDictionary Source="/Assets/generic.shared.xaml"/>--> </ResourceDictionary.MergedDictionaries> </ResourceDictionary> </Application.Resources>
and then I am able to correctly see the page again.
Now the app works as expected so this is only a designer issue,
but I want you to signal in case you're able to fix it
This is the error I get.
Best Regards
Roberto Dalmonte

Hello Roberto,
I followed the steps you suggested and was unable to reproduce the behavior you're describing. I created a sample using the XamSchedule in a User Control and included the generic.shared.xaml file in the Merged Dictionaries for the application. I then opened the Main Page in design view and the Calendar appeared as expected
I have attached the sample project I used to test this. Please test this project on your PC; whether or not it works correctly may help indicate the nature of this problem.
If the project does not work correctly, this indicates either a problem possibly specific to your environment, or a difference in the DLL versions we are using. My test was performed using version 11.2.20112.1012 in NetAdvantage for WPF 2011 Volume 2.
If the project does show the product feature working correctly, this indicates a possible problem in the code of your application. It will help if you can provide a small, isolated sample application that demonstrates the behavior you are seeing.
Or, if this sample project is not an accurate demonstration of what you're trying to do, please feel free to modify it and send it back, or send a small sample project of your own if you have one.
Please let me know if I can provide any further assistance.
Sincerely,
Valerie
