  <!-- Warning BG8401: Skipping Com.Brother.Ptouch.Sdk.LabelInfo.LabelColor, due to a duplicate field, method or nested type name

       This one is a bit tricky. Let's first just try removing the whole
       LabelColor nested class:

       <remove-node path="api/package[@name='com.brother.ptouch.sdk']/class[@name='LabelInfo.LabelColor']" />

       Now we see an interesting new warning:
       Warning BG8400: unexpected field type com.brother.ptouch.sdk.LabelInfo.LabelColor in managed type Com.Brother.Ptouch.Sdk.LabelInfo

       So there's still something named "LabelColor" in `LabelInfo`!
       Now let's check in `obj/Debug/api.xml` to find this name. It
       turns out that `LabelInfo` contains a field named "labelColor",
       _in addition_ to the nested class named "LabelColor". This causes
       a conflict in the C# binding because the field is automatically
       capitalized to "LabelColor". We can resolve the conflict by
       changing the C# name of either the field or the class. For this
       example, I'll rename the nested class. -->

  <!-- Many of the remaining BG8401 warnings are similar, but are caused
       by a conflict with a pair of getter/setter methods instead of a

       from the binding entirely. -->

  <!-- Warning BG8402: Skipping JP.CO.Brother.Adev.Devicefinder.Lib.ISnmpContextBasisFace.VersionId, due to a duplicate field

       This is yet another variation on the problem, this time caused by
       the presence of a string constant field in an interface (not
       possible in C#). The bindings generator creates abstract classes
       to hold these fields, resulting in a conflict due to inheritance.

       In particular, the abstract `SnmpContextFace` class contains
       _both_ its own `VersionId` field _and_ the inherited
       `BasisFaceVersionId` field. -->

  <!-- Warning CS0114: `JP.CO.Brother.Adev.Devicefinder.Lib.SnmpContext.Clone()' hides inherited member `Java.Lang.Object.Clone()'. To make the current member override that implementation, add the override keyword. Otherwise add the new keyword

       The bindings generator doesn't see that this is an override
       because the `visibility` is set to `public` while
       `Java.Lang.Object.Clone()` is `protected`. Changing the
       visibility to match allows the bindings generator to mark this as
       an override. -->

It improved the structure of the project, however I get a Java.Lang.ClassNotFoundException evrey time I try to access any of the classes in the jar. Any advice?

I have added some additional properties not included in the above Gist:
