Microsoft.Data.SqlClient 6.1.0-preview2.25178.5
Microsoft SqlClient Data Provider for SQL Server
Microsoft.Data.SqlClient is a .NET data provider for Microsoft SQL Server and the Azure SQL family of databases. It grew from a union of the two System.Data.SqlClient components which live independently in .NET and .NET Framework. Going forward, support for new SQL Server and Azure SQL features will only be implemented in Microsoft.Data.SqlClient.
Supportability
The Microsoft.Data.SqlClient package supports the following environments:
- .NET Framework 4.6.2+
- .NET 8.0+
Download
The Microsoft.Data.SqlClient NuGet package is available on NuGet.org.
SNI Package References
When targeting .NET Framework on Windows, a package reference to Microsoft.Data.SqlClient.SNI loads native Microsoft.Data.SqlClient.SNI.<platform>.dll libraries into the client's build directories.
When targeting .NET on Windows, a package reference to Microsoft.Data.SqlClient.SNI.runtime loads arm64, x64 and x86 native Microsoft.Data.SqlClient.SNI.dll libraries into subdirectories in the client's build directory.
