XAML designer is unable to see namespace (VS2012 and Blend too)

Question

I have working solution one one computer, this solution even show me my namespaces in XAML designer code IntelliSense when I start "xmlns" typing

But after move app on second computer (same path) I am in situation when this don't work and XAML designer don't want display XAML because "some custome element have not been build yet" as I have design time binding.

Situation :

- solution built and run (Native / Mixed , x86 for Local and also for Simulator) ok

- one root namespace "A" where is MainPage and under it I have A.Data namespace where data binding classes resides

- #include with .h which defines "A.Data" is in main page .cpp and .h files

- in Debug folder I have A.winmd file, I can see A.Data namespace

- Vs2012 loads A.winmd file correctly (verified with Process Monitor)

but XAML designer is still unable to load namespace (or included classes) :-(((

Hi,

Did you set DependentUpon property in vcxproj file?
Right Click your project->Unload Project, Right Click again->Edit your project name.vcxproj

You should add it like this
  <ItemGroup>
    <ClInclude Include="pch.h" />
    <ClInclude Include="App.xaml.h">
        <DependentUpon>App.xaml</DependentUpon>
    </ClInclude>
    <ClInclude Include="MainPage.xaml.h">
        <DependentUpon>MainPage.xaml</DependentUpon>
    </ClInclude>
  </ItemGroup>

Best regards,
Jesse

I didn't set this but I have it set so this is not this case :-(

I found it - designer is running under different user token and thus don't see subst/mapped drives from user.
