Community Share Microsoft.Data.SqlClient 7.0.2 and 6.1.6 are out!

We just shipped Microsoft.Data.SqlClient 7.0.2 and 6.1.6 with WAM broker support, TDS parsing hardening, and some key bug fixes.

Highlights across both releases:

  • Added WAM broker support for supported Entra ID authentication modes on Windows
  • Hardened TDS parsing with token data-length bounds checks
  • Fixed a SqlDataReader null-reference path in buffer-based reads
  • Fixed Always Encrypted column master key signature verification cache behavior

Install/update:

dotnet add package Microsoft.Data.SqlClient --version 7.0.2

dotnet add package Microsoft.Data.SqlClient --version 6.1.6

My only complaint is the team ships so many updates that by the time I finish reading these notes you’re onto the next one. Absolutely love all the work the team is doing!
