 ## Counting Documents
 
-Now that we’ve inserted 101 documents (the 100 we did in the loop, plus the first one), we can check to see if we have them all using the [`Count`]({{< apiref "M_MongoDB_Driver_IMongoCollection_1_Count" >}}) or [`CountAsync`]({{< apiref "M_MongoDB_Driver_IMongoCollection_1_CountAsync" >}}) methods. The following code should set the value of count to 101.

 All the create, read, update, and delete (CRUD) operations take a similar form and are defined on the [`IMongoCollection<TDocument>`]({{< apiref "T_MongoDB_Driver_IMongoCollection_1" >}}) interface. All the required fields take the form of a positional parameter and, if any options exists, they are passed in as an instance of an options class. All methods are available in both synchronous and asynchronous versions. For example, the following method signatures exists:
 
 ```csharp
-long Count(FilterDefinition<TDocument> filter, CountOptions options = null);
+long CountDocuments(FilterDefinition<TDocument> filter, CountOptions options = null);
 ```
 ```csharp
-Task<long> CountAsync(FilterDefinition<TDocument> filter, CountOptions options = null);
+Task<long> CountDocumentsAsync(FilterDefinition<TDocument> filter, CountOptions options = null);
 ```
 
 As described, the `filter` is required and the `options` can be omitted.

 ```csharp
-var count = collection.Count(new BsonDocument());
+var count = collection.CountDocuments(new BsonDocument());
 ```
 ```csharp
-var count = await collection.CountAsync(new BsonDocument());
