 While the specification pattern is older than C# lambda expressions, it's generally compared to expressions. Some developers may think it's not needed anymore and we can directly pass expressions to a repository or to a domain service as shown below:
 
-```
+````csharp
 var count = await _customerRepository.CountAsync(c => c.Balance > 100000 && c.Age => 18);
-```

 Since ABP's [Repository](Repositories.md) supports Expressions, this is a completely valid use. You don't have to define or use any specification in your application and you can go with expressions.
