What is the difference between first() and firstordefault() selector methods in linq?..

Answer / Rajneesh Kumar Gautam

The `first()` method throws a `InvalidOperationException` if no elements are found in the sequence, while the `FirstOrDefault()` method returns a default value (usually null) when no elements are found. This makes `FirstOrDefault()` safer to use when dealing with potentially empty sequences.
