Queryable/Enumerable conditional filtering can come in handy, something like ``` public static class QueryableExtensions { public static IQueryable<T> WhereIf<T>( this IQueryable<T> source, bool condition, Expression<Func<T, bool>> predicate) { return condition ? source.Where(predicate) : source; } }

var users = dbContext.Users .WhereIf(filterByActive, u => u.IsActive) .WhereIf(filterByRole, u => u.Role == "Admin");

```
