Hello JSW W.,
I've tried to create a new assembly which contains Nevron.Presentation.dll, Nevron.System.dll and Nevron.UI.WinForm.Skins.dll assemblies using ILMerge.
Then I referenced this new assembly and I was able to compile and ran my test project successfully.
To be able to apply skin you should change the value of NSkinResource.AssemblyName property to the name of the assembly that contain Nevron.UI.WinForm.Skins assembly.
Also, if you using Visual Studio 2010 you should change the value of Target Framework property in your project properties to .NET Framework 4.
I hope it helps.
