Bump Microsoft.Data.SqlClient from 7.1.0-preview1.26124.5 to 7.1.0-preview2.26190.5

[dependabot]

Updated Microsoft.Data.SqlClient from 7.1.0-preview1.26124.5 to 7.1.0-preview2.26190.5.

Release notes

Sourced from Microsoft.Data.SqlClient's releases.

7.1.0-preview2

This update brings the following changes since the 7.1.0-preview1 release.

Package version alignment: The Microsoft.Data.SqlClient driver and its companion packages continue the aligned versioning introduced in 7.0.2. All five packages listed below ship together as 7.1.0-preview2. (Microsoft.SqlServer.Server continues to version independently and remains at 1.0.0.) Applications that reference Microsoft.Data.SqlClient.Extensions.Azure must upgrade it to 7.1.0-preview2 when upgrading Microsoft.Data.SqlClient.

Compatibility guarantee: All aligned assemblies ship with FileVersion 7.1.0.x and AssemblyVersion 7.0.0.0 — unchanged from 7.0.2 — so upgrading from 7.0.2 to 7.1.0-preview2 does not require any new .NET Framework strong-name binding redirects.

Packages in this release

Microsoft.Data.SqlClient 7.1.0-preview2

Added

• SqlConnection.GetSchemaAsync overloads with CancellationToken support (#​3005)
• SQL Graph pseudo-column aliases ($node_id, $edge_id, $from_id, $to_id) accepted in SqlBulkCopy mappings (#​3677)
• SqlBatchCommand.CommandBehavior and SqlBatch.ExecuteReader(CommandBehavior) are now honored (#​4125)
• Configurable idle connection timeout via Connection Idle Timeout / SqlConnectionStringBuilder.IdleTimeout (opt-in via Switch.Microsoft.Data.SqlClient.UseLegacyIdleTimeoutBehavior=false) (#​4295)

Changed

• Connect Timeout now propagates through the pool when Switch.Microsoft.Data.SqlClient.UseOverallConnectTimeoutForPoolWait=true is set (default off; introduces a Microsoft.Bcl.TimeProvider dependency) (#​4270)
• SQL Server 2025 json type added to the DataTypes collection returned by SqlConnection.GetSchema (#​3858)
• Internal state-machine hardening via Interlocked.CompareExchange guards (#​4267)
• Internal cleanup of connection-options inheritance and related pool interfaces (#​4237, #​4261, #​4235, #​4415, #​4334)
• LCID hardcoded mappings to avoid repeated culture lookups (#​4212)
• Allocation reductions on SqlErrorCollection and null-return paths (#​4157, #​4099, #​4102)
• Improved EnclaveDiffieHellmanInfo.Size accuracy (#​4346)
• SqlVector<float> serialization is now explicitly little-endian for cross-architecture consistency (#​3861)
• Bundled .NET 10 SDK updated to 10.0.300 (#​4287)

Fixed

• NullReferenceException in SqlCommand.Cancel() when the connection has already been torn down (#​4372)
• Always Encrypted CMK signature verification incorrectly reusing cached results after a prior failure (#​4339)
• Missing TDS token / feature-ack length bounds checks (spoofing server could trigger unbounded allocations) (#​4340)
• SqlBulkCopy failing in least-privilege environments (#​4306)
• Always Encrypted CekMdVersion / EkValueCount reads aligned with the TDS specification (#​4240)
• LoginWithFailover parser-state validation (#​4140)
• SPN during login now uses the resolved port instead of instance name for Protocol=None / Protocol=Admin (#​4180)
• Race in SqlConnection.TryOpenInner that could surface as InvalidCastException now returns a deterministic InvalidOperationException (#​4179)
• Multiple CancellationTokenSource leaks in SqlDataReader, SqlConnection, SqlCommand reconnect paths, and sequential-stream helpers (#​4009)
• Docs fix for server certificate configuration (#​4408)

Removed (breaking)

• SQL Server 7.0 / 2000 code paths removed; Type System Version=SQL Server 2000 now throws ArgumentException at open. Applications should switch to Latest (or another supported value). No change to server-version support — 7.0 / 2000 were already rejected during login version negotiation. (#​4015)

Microsoft.Data.SqlClient.Extensions.Azure 7.1.0-preview2

Added — WAM (Windows Account Manager) broker support for Entra ID authentication (Windows only) (#​4288, #​4388)
