| # Release Notes | ||
|
|
||
| ## Microsoft.Data.SqlClient 5.0.0 released 5 August 2022 | ||
|
|
||
| This update includes the following changes over the 4.1 release: | ||
|
|
||
| ### Breaking changes | ||
|
|
||
| - Added a dependency on the [Microsoft.SqlServer.Server](https://github.com/dotnet/SqlClient/tree/main/src/Microsoft.SqlServer.Server) package. This new dependency may cause namespace conflicts if your application references that namespace and still has package references (direct or indirect) to System.Data.SqlClient from .NET Core. | ||
| - Dropped classes from the `Microsoft.Data.SqlClient.Server` namespace and replaced them with supported types from the [Microsoft.SqlServer.Server](https://github.com/dotnet/SqlClient/tree/main/src/Microsoft.SqlServer.Server) package.[#1585](https://github.com/dotnet/SqlClient/pull/1585) The affected classes and enums are: | ||
| - Microsoft.Data.SqlClient.Server.IBinarySerialize -> Microsoft.SqlServer.Server.IBinarySerialize | ||
| - Microsoft.Data.SqlClient.Server.InvalidUdtException -> Microsoft.SqlServer.Server.InvalidUdtException | ||
| - Microsoft.Data.SqlClient.Server.SqlFacetAttribute -> Microsoft.SqlServer.Server.SqlFacetAttribute | ||
| - Microsoft.Data.SqlClient.Server.SqlFunctionAttribute -> Microsoft.SqlServer.Server.SqlFunctionAttribute | ||
| - Microsoft.Data.SqlClient.Server.SqlMethodAttribute -> Microsoft.SqlServer.Server.SqlMethodAttribute | ||
| - Microsoft.Data.SqlClient.Server.SqlUserDefinedAggregateAttribute -> Microsoft.SqlServer.Server.SqlUserDefinedAggregateAttribute | ||
| - Microsoft.Data.SqlClient.Server.SqlUserDefinedTypeAttribute -> Microsoft.SqlServer.Server.SqlUserDefinedTypeAttribute | ||
| - (enum) Microsoft.Data.SqlClient.Server.DataAccessKind -> Microsoft.SqlServer.Server.DataAccessKind | ||
| - (enum) Microsoft.Data.SqlClient.Server.Format -> Microsoft.SqlServer.Server.Format | ||
| - (enum) Microsoft.Data.SqlClient.Server.SystemDataAccessKind -> Microsoft.SqlServer.Server.SystemDataAccessKind | ||
| - Dropped support for .NET Framework 4.6.1 [#1574](https://github.com/dotnet/SqlClient/pull/1574) | ||
|
|
||
|
|
||
| ### Added | ||

|
|
||
|
|
||
| ### TDS 8 Enhanced Security | ||
|
|
||
| To use TDS 8, specify Encrypt=Strict in the connection string. Strict mode disables TrustServerCertificate (always treated as False in Strict mode). HostNameInCertificate has been added to help some Strict mode scenarios. TDS 8 begins and continues all server communication inside a secure, encrypted TLS connection. | ||
|
|
||
| New Encrypt values have been added to clarify connection encryption behavior. Encrypt=Mandatory is equivalent to Encrypt=True and encrypts connections during the TDS connection negotiation. Encrypt=Optional is equivalent to Encrypt=False and only encrypts the connection if the server tells the client that encryption is required during the TDS connection negotiation. | ||
|
|
||
| HostNameInCertificate can be specified in the connection string when using aliases to connect with encryption to a server that has a server certificate with a different name or alternate subject name than the name used by the client to identify the server (DNS aliases, for example). Example usage: HostNameInCertificate=MyDnsAliasName | ||
|
|
||
| ### Server SPN | ||
|
|
||
| When connecting in an environment that has unique domain/forest topography, the ServerSPN/Server SPN and FailoverServerSPN/Failover Server SPN connection string settings can be used to override the auto-generated server SPNs used in the library when authenticating with integrated authentication in a domain environment. | ||
|
|
||
| ### Support for Aliases | ||
|
|
||
| Users can configure Aliases by using the SQL Server Configuration Manager. These are stored in the Windows registry and are already supported when targeting .NET Framework. This release brings support for aliases when targeting .NET or .NET Core on Windows. | ||
|
|
||
|
|
||
| ### SQL Data Source Enumerator support | ||
| Provides a mechanism for enumerating all available instances of SQL Server within the local network. | ||
| ```cs | ||
| using Microsoft.Data.Sql; | ||
|
|
||
| static void Main() | ||
| { | ||
| // Retrieve the enumerator instance and then the data. | ||
| SqlDataSourceEnumerator instance = | ||
| SqlDataSourceEnumerator.Instance; | ||
| System.Data.DataTable table = instance.GetDataSources(); | ||
|
|
||
| // Display the contents of the table. | ||
| DisplayData(table); | ||
|
|
||
| Console.WriteLine("Press any key to continue."); | ||
| Console.ReadKey(); | ||
| } | ||
|
|
||
| private static void DisplayData(System.Data.DataTable table) | ||
| { | ||
| foreach (System.Data.DataRow row in table.Rows) | ||
| { | ||
| foreach (System.Data.DataColumn col in table.Columns) | ||
| { | ||
| Console.WriteLine("{0} = {1}", col.ColumnName, row[col]); | ||
| } | ||
| Console.WriteLine("============================"); | ||
| } | ||
| } | ||
| ``` | ||
|
|
||
| ### New Attestation protocol `None` | ||
| A new attestation protocol called `None` is allowed in the connection string. This protocol will allow users to forgo enclave attestation for `VBS` enclaves. When this protocol is set, the enclave attestation URL property is optional. | ||
|
|
||
| Connection string example: | ||
|
|
||
| ```cs | ||
| //Attestation protocol NONE with no URL | ||
| "Data Source = {server}; Initial Catalog = {db}; Column Encryption Setting = Enabled; Attestation Protocol = None;" | ||
|
|
||
| ``` | ||
|
|
||
| ### Suppress insecure TLS warnings | ||
| A security warning is output to the console if a TLS version less than 1.2 is used to negotiate encryption with the server. This warning can be suppressed on connections where `Encrypt = false` by enabling the following AppContext switch at application startup: | ||
| ```cs | ||
| Switch.Microsoft.Data.SqlClient.SuppressInsecureTLSWarning | ||
| ``` | ||
|
|
||
| ## Target Platform Support | ||
|
|
||
| - .NET Framework 4.6.2+ (Windows x86, Windows x64) | ||
| - .NET Core 3.1+ (Windows x86, Windows x64, Windows ARM64, Windows ARM, Linux, macOS) | ||
