How to write DependentUpon clauses for C# files in subdirectories?

Question

We are trying to get our C# application to compile and run with both

Visual Studio 10 (with the Microsoft compiler), on Windows, and
MonoDevelop with gmcs, on Linux

However, sections like this in the .csproj files (for Visual Studio):

<Compile Include="Foo\Bar.cs" />
<EmbeddedResource Include="Foo\Bar.resx">
    <DependentUpon>Bar.cs</DependentUpon>
</EmbeddedResource>

must be changed as follows before they will work with MonoDevelop/gmcs (if not, at runtime, resources.GetObject() will throw a MissingManifestResourceException):

<Compile Include="Foo\Bar.cs" />
<EmbeddedResource Include="Foo\Bar.resx">
    <DependentUpon>Foo\Bar.cs</DependentUpon>
</EmbeddedResource>

How to rewrite this into a form they will both accept? (Short of deleting the DependentUpon element, of course.)

Meanwhile I have researched a couple of ways to deal with the situation.

For instance, it is apparently possible to add Condition attributes with the value $(VisualStudioVersion) != '' in order to make them conditional on whether Visual Studio is being used.

However, on a whim (after reading this answer) I tried something entirely different: I replaced my nested namespaces

namespace Baz
{
    namespace Bar
    {
        [...]
    }
}

with dotted namespace notation:

namespace Baz.Bar
{
    [...]
}

and voilà, the MissingManifestResourceException no longer exists, even with the original DependentUpon clause.

Problem solved, but I don't know why.
