> .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}
