 1. Start tracing using the following command line.
-```
-xperf -start trace -f myTrace.etl -on *Microsoft.Data.SqlClient.EventSource
-```
+
+   ```
+   xperf -start trace -f myTrace.etl -on *Microsoft.Data.SqlClient.EventSource

+   
 2. Run the native SNI tracing example to connect to SQL Server.

 3. Stop tracing using the following command line.
-```
-xperf -stop trace
-```
+
+   ```
+   xperf -stop trace
+   ```
+   
 4. Use PerfView to open the myTrace.etl file specified in Step 1. The SNI tracing log can be found with `Microsoft.Data.SqlClient.EventSource/SNIScope` and `Microsoft.Data.SqlClient.EventSource/SNITrace` event names.
