 as it's a common use-case to swapout to use Sqlite's in-memory provider for faster tests. 
 But as Sqlite doesn't provide async API's under-the-hood we fallback to *pseudo async* support where we just wrap its synchronous responses in `Task` results. 
 
-## Dynamic Result Sets
-
-There's new support for returning unstructured resultsets letting you Select `List<object>` instead of having results mapped to a concrete Poco class, e.g:
-
-```csharp
-db.Select<List<object>>(db.From<Poco>()
-  .Select("COUNT(*), MIN(Id), MAX(Id)"))[0].PrintDump();
-```
-
-Output of objects in the returned `List<object>`:
-
-    [
-        10,
-        1,
-        10
-    ]
-
-You can also Select `Dictionary<string,object>` to return a dictionary of column names mapped with their values, e.g:
-
-```csharp
-db.Select<Dictionary<string,object>>(db.From<Poco>()
-  .Select("COUNT(*) Total, MIN(Id) MinId, MAX(Id) MaxId"))[0].PrintDump();
-```
-
-Output of objects in the returned `Dictionary<string,object>`:
-
-    {
-        Total: 10,
-        MinId: 1,
-        MaxId: 10
-    }
-
-and can be used for API's returning a **Single** row result:
-
-```csharp
-db.Single<List<object>>(db.From<Poco>()
-  .Select("COUNT(*) Total, MIN(Id) MinId, MAX(Id) MaxId")).PrintDump();
-```
-
-or use `object` to fetch an unknown **Scalar** value:
-
-```csharp
-object result = db.Scalar<object>(db.From<Poco>().Select(x => x.Id));
