Welcome to the home of Microsoft ADO.NET driver for SQL Server aka Microsoft.Data.SqlClient GitHub repository.
Microsoft.Data.SqlClient is a data provider for Microsoft Sql Server. 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.
The Microsoft.Data.SqlClient package supports below environments:
- .NET Framework 4.6+
- .NET Core 2.1+
- .NET Standard 2.0+.
The source code of this library is now available under MIT license.
The Microsoft.Data.SqlClient NuGet package is available on NuGet.org.
For the .NET Framework driver on Windows, a package reference to Microsoft.Data.SqlClient.SNI loads x64 and x86 platform specific 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 platform specific SNI.dll libraries into the client's build directories.
