-or-

Addr

-or-

Network Address|N/A|The name or network address of the instance of SQL Server to which to connect. The port number can be specified after the server name:

`server=tcp:servername, portnumber`

When specifying a local instance, always use (local). To force a protocol, add one of the following prefixes:

`np:(local), tcp:(local), lpc:(local)`

You can also connect to a LocalDB database as follows:

`server=(localdb)\\myInstance`

For more information about LocalDB, see [SqlClient Support for LocalDB](/sql/connect/ado-net/sql/sqlclient-support-localdb).

**Data Source** must use the TCP format or the Named Pipes format.

TCP format is as follows:

- tcp:\\\
- tcp:\,\

The TCP format must start with the prefix "tcp:" and is followed by the database instance, as specified by a host name and an instance name. This format is not applicable when connecting to Azure SQL Database. TCP is automatically selected for connections to Azure SQL Database when no protocol is specified.

The host name MUST be specified in one of the following ways:

- NetBIOSName
- IPv4Address
- IPv6Address

The instance name is used to resolve to a particular TCP/IP port number on which a database instance is hosted. Alternatively, specifying a TCP/IP port number directly is also allowed. If both instance name and port number are not present, the default database instance is used.

The Named Pipes format is as follows:

- np:\\\\\pipe\\

The Named Pipes format MUST start with the prefix "np:" and is followed by a named pipe name.

The host name MUST be specified in one of the following ways:

- NetBIOSName
- IPv4Address
- IPv6Address

The pipe name is used to identify the database instance to which the .NET application will connect.

If the value of the **Network** key is specified, the prefixes "tcp:" and "np:" should not be specified. **Note:** You can force the use of TCP instead of shared memory, either by prefixing **tcp:** to the server name in the connection string, or by using **localhost**.| |Enclave Attestation Url|N/A|Gets or sets the enclave attestation URL to be used with enclave based Always Encrypted.| -|Encrypt|'false' in v3.1 and older

Possible values are:

Implicit Unbind causes the connection to detach from the transaction when it ends. After detaching, additional requests on the connection are performed in autocommit mode.

After the transaction has ended, additional requests are performed in autocommit mode.

If the system ends the transaction (in the scope of a using block) before the last command completes, it will throw .

Explicit Unbind causes the connection to remain attached to the transaction until the connection is closed or an explicit `SqlConnection.TransactionEnlist(null)` is called. Beginning in .NET Framework 4.0, changes to Implicit Unbind make Explicit Unbind obsolete.
