Microsoft SqlClient Data Provider for SQL Server

Welcome to the home of the Microsoft ADO.NET driver for SQL Server aka the Microsoft.Data.SqlClient GitHub repository.

Microsoft.Data.SqlClient is a data provider for Microsoft SQL Server and Azure SQL Database. Now in General Availability, it is a union of the two System.Data.SqlClient components which live independently in .NET Framework and .NET Core. Going forward, support for new SQL Server features will be implemented in Microsoft.Data.SqlClient.

Supportability

The Microsoft.Data.SqlClient package supports the below environments:

  • .NET Framework 4.6+
  • .NET Core 2.1+
  • .NET Standard 2.0+.

The source code of this library is now available under the MIT license.

Download

The Microsoft.Data.SqlClient NuGet package is available on NuGet.org.

SNI Package References

For the .NET Framework driver on Windows, a package reference to Microsoft.Data.SqlClient.SNI loads x64 and x86 native SNI.dll libraries into the client's build directories.

For the .NET Core driver on Windows, a package reference to runtime.native.System.Data.SqlClient.sni loads arm64, x64 and x86 native SNI.dll libraries into the client's build directories.

Note When referencing the native SNI.dll on Windows, the Microsoft Visual C++ Redistributable is required to be installed: The latest supported Visual C++ downloads
