> .NET service client receives Object[] instead of strongly typed array from a .NET service. 
> There was another already resolved similar issue IGNITE-12823 that addressed the problem of using arrays as parameters. The problem of using arrays as results still exists.
> h3. Reproducer
> A .NET service returning an array of user-defined types is deployed:
> {code:c#}
> public interface ITestService
> {
>     Parameter[] TestReturnParametersArray();
> }
> public sealed class Parameter
> {
>     public int Id { get; set; }
>     public int[] Values { get; set; }
> }
> {code}
> A .NET client calls the service:
> {code:c#}
> Parameter[] res = svcProxy.TestReturnParametersArray()
> {code}
> The service call fails with exception:
> {code}
> System.InvalidCastException : Unable to cast object of type 'System.Object[]' to type 'Parameter[]'.
> {code}
