d:DesignData issue, Visual Studio 2010 cant build after adding sample design data with Expression Bl
- by Valko
Hi,
VS 2010 solution and Silverlight project builds fine, then:
I open MyView.xaml view in Expression Blend 4
Add sample data from class (I use my class defined in the same project)
after I add new sample design data with Expression blend 4, everything looks fine, you see the added sample data in the EB 4 fine, you also see the data in VS 2010 designer too.
Close the EB 4, and next VS 2010 build is giving me this errors:
Error 7 XAML Namespace http://schemas.microsoft.com/expression/blend/2008 is not resolved. C:\Code\source\...myview.xaml
and:
Error 12 Object reference not set to an instance of an object. ... TestSampleData.xaml
when I open the TestSampleData.xaml I see that namespace for my class used to define sample data is not recognized.
However this namespace and the class itself exist in the same project!
If I remove the design data from the MyView.xaml:
d:DataContext="{d:DesignData /SampleData/TestSampleData.xaml}"
it builds fine and the namespace in TestSampleData.xaml is recognized this time??
and then if add:
d:DataContext="{d:DesignData /SampleData/TestSampleData.xaml}"
I again see in the VS 2010 designer sample data, but the next build fails and again I see studio cant find the namespace in my TestSampleData.xaml containing sample data.
That cycle is driving me crazy. Am I missing something here, is it not possible to have your class defining sample design data in the same project you have the MyView.xaml view??
cheers
Valko
