<ItemGroup>add .cs files and embedded resources

[khoshbin]

I want to add some c# files and folders to .csproj file:

<Compile Include="financial\Invoice.cs" />
<Compile Include="financial\Invoice.Designer.cs">
  <DependentUpon>Invoice.cs</DependentUpon>
</Compile>

also I want to add some embedded resource:

  <ItemGroup>
    <EmbeddedResource Include="Images\Images.Invoice.png" />

Is it possible with your library? if yes, how?
