commit bdba2e5bf1aeb8dade4260604f2d4e48ab4a3f64
Author: Curt Hagenlocher <c...@hagenlocher.org>
AuthorDate: Wed Apr 16 18:57:34 2025 -0700

    fix(csharp/src/Drivers/Apache/Thrift): Generated Thrift-based code should 
not be exposed publicly (#2710)
    
    The Thrift classes in the HiveServer2-based drivers are intended to be
    internal implementation details and not exposed publicly. This PR
    changes their visibility from public to internal.
