The Iterator

Nesting files in Visual Studio projects is as simple as (pun intended) opening your project file into a text editor, finding your reference to a project file and adding <DependentUpon>Class.cs</DependentUpon> within the element.

However, there’s a catch. Nesting the files causes the file names to be overwritten. In this case, the .hbm.xml suffix gets dropped. That effectively prevents Configuration.AddAssembly() from finding the mapping information. A way around this pitfall is defining the dependency as follows:

<EmbeddedResource include="ServiceRequest.hbm.xml">
<DependentUpon>ServiceRequest.cs</DependentUpon>
<LogicalName>ServiceRequest.hbm.xml</LogicalName>
</EmbeddedResource>

Thanks go to Sami for cracking this nut with me.
