You do not have to explicitly specify the generic parameter TModel. Instead, you can let the C# or Visual Basic type inference engine determine the generic parameter TMode by omitting it.
The TryUpdateModel method is like the UpdateModel method except that the TryUpdateModel method does not throw an InvalidOperationException exception if the updated model state is not valid.
