 ### Query Digital Twin
@@ -190,22 +207,24 @@ await DigitalTwinsClient.DeleteDigitalTwinAsync(twin.Key).ConfigureAwait(false);
 To update a component or in other words to replace, remove and/or add a component property or subproperty within Digital Twin, you would need id of a digital twin, component name and application/json-patch+json operations to be performed on the specified digital twin's component. Here is the sample code on how to do it.  
 
 ```C# Snippet:DigitalTwinsSampleUpdateComponent
-// Update Component with replacing property value
-string propertyPath = "/ComponentProp1";
-string propValue = "New Value";
-
+// Update Component1 by replacing the property ComponentProp1 value
 var componentUpdateUtility = new UpdateOperationsUtility();
-componentUpdateUtility.AppendReplaceOp(propertyPath, propValue);
+componentUpdateUtility.AppendReplaceOp("/ComponentProp1", "Some new value");
+string updatePayload = componentUpdateUtility.Serialize();
 
-Response<string> response = await DigitalTwinsClient.UpdateComponentAsync(twinId, SamplesConstants.ComponentPath, componentUpdateUtility.Serialize());
+Response<string> response = await DigitalTwinsClient.UpdateComponentAsync(dtId, "Component1", updatePayload);
+
+Console.WriteLine($"Updated component for digital twin {dtId}. Update response status: {response.GetRawResponse().Status}");
 ```
 
 ### Get Digital Twin Component
 
 Get a component by providing name of a component and id of digital twin it belongs to.
 
 ```C# Snippet:DigitalTwinsSampleGetComponent
-response = await DigitalTwinsClient.GetComponentAsync(twinId, SamplesConstants.ComponentPath).ConfigureAwait(false);
+response = await DigitalTwinsClient.GetComponentAsync(dtId, SamplesConstants.ComponentPath).ConfigureAwait(false);
+
+Console.WriteLine($"Get component for digital twin: \n{response.Value}. Get response status: {response.GetRawResponse().Status}");
 ```
