[v7.1.0-preview3] Update SNI package reference to 7.1.0-preview3

[priyankatiwari08]

Description

Updates the SNI package reference to the newly published 7.1.0-preview3 build, in preparation for the MDS v7.1.0-preview3 release.

Microsoft.Data.SqlClient.SNI and Microsoft.Data.SqlClient.SNI.runtime have both been published at 7.1.0-preview3.26226.3, aligning SNI's version numbering with MDS.

Why this is required

SniVersion was last set to 6.0.2 in #4337 and has not changed since, so v7.1.0-preview1 and preview2 both shipped against SNI 6.0.2. The derived range currently evaluates to:

[6.0.2, 7.0.0)

The upper bound is exclusive at 7.0.0, so the new 7.1.0-preview3 SNI falls outside the range and would never be picked up by floating resolution. Without this explicit bump, v7.1.0-preview3 would silently ship against SNI 6.0.x.

The rest of the version alignment is already in place — following the versioning consolidation in #4336, SqlClientNextVersion is set to 7.1.0-preview3 and the entire SqlClient family resolves from it. This change brings the SNI dependency in line so that everything points at preview3.

Change

A single property update. SniVersion is declared once and fans out automatically to:

• PackageVersion entries for Microsoft.Data.SqlClient.SNI and Microsoft.Data.SqlClient.SNI.runtime
• The $SniVersionRange$ token substituted into Microsoft.Data.SqlClient.nuspec

The derived range now evaluates to [7.1.0-preview3.26226.3, 8.0.0). The Split('.')[0] ceiling calculation correctly yields 7 despite the prerelease suffix, and a future stable 7.1.0 will still satisfy the range since prerelease sorts below release.

Validation

• dotnet restore resolves both packages at 7.1.0-preview3.26226.3; project.assets.json confirms the ranges as >= 7.1.0-preview3.26226.3 < 8.0.0
• dotnet build -f net9.0 — succeeded, 0 warnings, 0 errors
• dotnet build -f net462 — succeeded, 0 warnings, 0 errors

Checklist

• Verified against the published SNI packages on the consumed feed
• Restore and build succeed for both netfx and netcore target frameworks
• No remaining references to the previous SNI version
• Ensure no breaking changes introduced
• Tests added or updated — n/a, dependency version change only
• Public API changes documented — n/a, no API surface change

Release notes for v7.1.0-preview3 will follow in a separate PR.
