public class AddNumbersQuery : IQuery<(int, int), int> {} public class AddNumbersQueryHandler : IQueryHandlerIn this example, an `AddNumbersQuery` is defined with a tuple of two `int` parameters and an `int` result. The `AddNumbersQueryHandler` implements the `IQueryHandler` interface and makes a RPC call to a hypothetical `SomeRpcClient` to add the two numbers and return the result. Package library: System.ServiceModel Note: These are just two examples of how the `IQueryHandler` Execute method can be used. The package library can vary depending on the specific implementation and dependencies used in a project.{ public async Task Execute(AddNumbersQuery query) { var result = await SomeRpcClient.AddNumbersAsync(query.Parameter.Item1, query.Parameter.Item2); return result; } }
