Creating a repository method to check whether a question exists

Let's implement the QuestionExists method now, following the same approach as the previous methods:

public bool QuestionExists(int questionId){  using (var connection = new SqlConnection(_connectionString))  {    connection.Open();    return connection.QueryFirst<bool>(      @"EXEC dbo.Question_Exists @QuestionId = @QuestionId",       new { QuestionId = questionId }    );  }}

We are using the Dapper QueryFirst method rather than QueryFirstOrDefault because the stored procedure will always return a single record.
