dependabot · 2025-11-06T03:28:06Z

Updated Microsoft.Data.SqlClient from 5.1.5 to 6.1.2.

Release notes

Sourced from Microsoft.Data.SqlClient's releases.

6.1.2

This update brings the below changes over the previous stable release:

Fixed

Fixed an issue where initializing PerformanceCounters would throw System.InvalidOperationException #3629
Fixed an issue where a Custom SqlClientAuthenticationProvider was being overwritten by default implementation. #3651
Fixed a concurrency issue in connection pooling where the number of active connections could be lower than the configured maximum pool size. #3653

6.1.1

This update includes the following changes since the 6.1.0 release:

Fixed

Reverted changes related to improving partial packet detection, fixup, and replay functionality. This revert addresses regressions introduced in 6.1.0. (#3556)
Applied reference assembly corrections supporting vector, fixed JSON tests, and ensured related tests are enabled. #3562
Fixed SqlVector<T>.Null API signature in Reference assembly. #3521

Changed

Upgraded Azure.Identity and other dependencies to newer versions. (#3538) (#3552)

6.1.0

Release Notes

[!WARNING]
This release version is delisted from NuGet.org and is no longer supported.
It contains critical bugs that make it unsuitable for use.

Stable Release 6.1.0 - 2025-07-25

This update brings the following changes since the 6.0.2 stable release:

Added

Added dedicated SQL Server vector datatype support

What Changed:

Optimized vector communications between MDS and SQL Server 2025, employing a custom binary format over the TDS protocol. (#3433, #3443)
Reduced processing load compared to existing JSON-based vector support.
Initial support for 32-bit single-precision floating point vectors.

Who Benefits:

Applications moving large vector data sets will see beneficial improvements to processing times and memory requirements.
Vector-specific APIs are ready to support future numeric representations with a consistent look-and-feel.

Impact:

Reduced transmission and processing times for vector operations versus JSON using SQL Server 2025 preview:
- Reads: 50x improvement
- Writes: 3.3x improvement
- Bulk Copy: 19x improvement
- (Observed with vector column of max 1998 size, and 10,000 records for each operation.)
Improved memory footprint due to the elimination of JSON serialization/deserialization and string representation bloat.
For backwards compatibility with earlier SQL Server Vector implementations, applications may continue to use JSON strings to send/receive vector data, although they will not see any of the performance improvements noted above.

Revived .NET Standard 2.0 target support

What Changed:

Support for targeting .NET Standard 2.0 has returned. (#3381)
Support had previously been removed in the 6.0 release, with the community voicing concerns.

Who Benefits:

Libraries that depend on MDS may seamlessly target any of the following frameworks:
- .NET Standard 2.0
- .NET Framework 4.6.2 and above
- .NET 8.0
- .NET 9.0
Applications should continue to target runtimes.

Preview Release 6.1.0-preview2.25178.5 - 2025-06-27

Revived .NET Standard 2.0 target support

What Changed:

Support for targeting .NET Standard 2.0 has returned. (#3381)
Support had previously been removed in the 6.0 release, with the [community voicing concerns] (Microsoft.Data.SqlClient 6.0 and .Net Standard dotnet/SqlClient#3115).

Who Benefits:

Libraries that depend on MDS may seamlessly target any of the following frameworks:
- .NET Standard 2.0
- .NET Framework 4.6.2 and above
- .NET 8.0
- .NET 9.0
Applications should continue to target runtimes.
- The MDS .NET Standard 2.0 target framework support does not include an actual implementation, and cannot be used with a runtime.
- An application's build/publish process should always pick the appropriate MDS .NET/.NET Framework runtime implementation.
- Custom build/publish actions that incorrectly try to deploy the MDS .NET Standard 2.0 reference DLL at runtime are not supported.

Impact:
