Not that I know of. I remember that there were some by Dr. Carlisle used in his SigAda tutorials and early mgnat distributions but since AdaCore implemented Ada for .Net towards the Ada 2005 standard, these samples no longer work (they used 'with type' instead of the new 'limited with')
I have now tried to convert the old 'extend .net class' sample to the GNAT GPL version and managed to get it working for .Net compact framework.
In the full .Net framework the compiler complains that declaring the new type is not allowed : 'stand-alone object of Java-convention tagged type not allowed'
If this is also true for the GNAT Pro version I will submit a bugreport :-)

Ok, the compiler from sourceforge is a good place to start. I used it for our projects too but we needed to have a commercial support so that's why AdaCore has now developed the GNAT Pro version.
I'm not sure if Dr. Martin Carlisle is still working on the sourceforge version. It has been untouched for quite some time now.

The GPL 2008 version on the libre site (libre.adacore.com) is also a good option. There were some issues with the integration in the MS Visual Studio but I have posted a fix for this in a previous thread.

This compiler also has some examples that demonstrate mixed language and .Net class extension usage.
