Looking at the number of JIRAs filed, it doesn't appear anyone is working on the C# version. I'd encourage you to go ahead with your patches.

Subject: Anyone working on C-Sharp version?
Is anyone working on the C-Sharp version of AVRO currently to either fix
issues, or most importantly, extend it to fully support Protocol's ?
I am currently looking at Serializers for two projects, and have been
playing with AVRO over the weekend in C-Sharp. During testing, I came
across a few issues, some of which I have fixed. (Nullable Types,
Multi-Dimensional array's in SpecificReader/Writer) which I needed for my
project. However, before I start creating fixes/patches etc (as per the
contributor guide on the wiki), I wanted to check to see if anyone else is
already working on it.
I'd quite like to collaborate with anyone who is interested in expanding the
C-Sharp version, (And expanding my understanding of it as well !)
