tag does not exist in XML namespace

Question

This error seems to be posted all over the place but each one seems to have its own solution, none of which solved my problem.

I am getting an error for a Resource D

Answer 1

it's an old question but, the problem comes from the .csproj. Be sure the "page" element is defined before the "compile" element in the "itemgroup" section.

Good :

  <ItemGroup>
...
<Page Include="ScreenComponents\StatusBar.xaml">
  <SubType>Designer</SubType>
  <Generator>MSBuild:Compile</Generator>
</Page>
<Compile Include="ScreenComponents\StatusBar.xaml.cs">
  <DependentUpon>StatusBar.xaml</DependentUpon>
</Compile>
…

Not good :

  <ItemGroup>
...
<Compile Include="ScreenComponents\StatusBar.xaml.cs">
  <DependentUpon>StatusBar.xaml</DependentUpon>
</Compile>
<Page Include="ScreenComponents\StatusBar.xaml">
  <SubType>Designer</SubType>
  <Generator>MSBuild:Compile</Generator>
</Page>
…
