Error setting property of local class name in WPF DesignData file
I have this DesignData file (compilation type set to DesignData) in a XAML file:
<local:FooModel xmlns:local="clr-namespace:MyProject"
Name="Sample" FullPath="C:/www" />
I have a FooModel
class inside a namespace MyProject
with these two properties. I am getting the Name property in XAML highlighted in red and this message:
Error 1 Because "microsoft.expression.markup.semantics.metadata.reflectiontypenode" is implemented in the same assembly, you must set the x: Name attribute and not the microsoft.expression.markup.semantics.metadata.ReflectionPropertyNode attribute.
I think the property is being Name
confused with something else. I mean a property of my class FooModel
and not something else. I am not getting warnings for FullPath
.

There is no way to reproduce this. Have a similar DesignData file, no problem including the Name property. You have no typo. The User Tool and User Namespace check are empty. I also suspect you have a strange build in your References list. Where did you get MS.Internal.Design ...? (was the project created in Blend?). In a standard VS generated project, this namespace does not appear on any of my assemblies. Check which assembly implements this namespace and try to remove it from the reference list.

I met the same error. The error disappears for a while after repairing the solution, but it appears after opening the corresponding DesignData file in Visual Studio (VS Professional, version 11.0.51106.01 Update 1).
I tried to remove the referenced assemblies and clear the Custom Tool and Custom Namespace values for this DesignData file. None of this worked. Pressing F12 in the xaml file doesn't divide anywhere, it only works for .cs files for me.
My decision
I got rid of this annoying error by specifying the full namespace: formname.propertyname in a separate xml element dedicated to it (instead of referencing it in the xml attribute of the parent class). In your case, this would mean:
<local:FooModel xmlns:local="clr-namespace:MyProject" FullPath="C:/www" >
<local:FooModel.Name>Sample</local:FooModel.Name>
</local:FooModel>
