|
||
| { | ||
| // 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` | ||
| new attestation protocol called `None` will be 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 ouptput on the console if the TLS version less than 1.2 is used to negotiate with the server. This warning could be suppressed on SQL connection while `Encrypt = false` by enabling the following AppContext switch on the application startup: | ||
| ```cs | ||
| Switch.Microsoft.Data.SqlClient.SuppressInsecureTLSWarning | ||
| ``` | ||
|
|

I believe we can remove 'None' attestation since it's already in 4.1
