How do I use SafeMode with the MongoDB C# driver

From documentation:

There are various level of SafeMode, and this class is used to represent those levels. SafeMode applies only to operations that don't already return a value (so it doesn't apply to queries or commands). It applies to the following MongoCollection methods: Insert, Remove, Save and Update.

The gist of SafeMode is that after an Insert, Remove, Save or Update message is sent to the server it is followed by a GetLastError command so the driver can verify that the operation succeeded. In addition, when using replica sets it is possible to verify that the information has been replicated to some minimum number of secondary servers.

The SafeMode class has static properties and methods that let you easily access common modes or create your own:

* SafeMode.False
* SafeMode.True
* SafeMode.WaitForReplications(int n)

The value for "n" includes the primary, so typically you want n >= 2.

I hope this is enough to understand the purpose of SafeMode.
