@jeking3 What csharp gen options are passed to produce source compatible
with this netcore lib? Any .thrift file I pass through `csharp:async` for
example uses old style begin/end but this netcore lib uses async/await
patterns, but I can't find any published reference for C# option to generate
corresponding output. Also the namespaces appear to differ. My reference point
is thrift-0.10.0.---
