             Summary: .NET Service can't assign correct type to passed array parameters
                 Key: IGNITE-13897
                 URL: https://issues.apache.org/jira/browse/IGNITE-13897
             Project: Ignite
          Issue Type: Bug
          Components: platforms
    Affects Versions: 2.9
            Reporter: Yaroslav Molochkov

This issue relates to IGNITE-12823.

Ignite client calls deployed service and fails with the following exception:
{code:java}
Apache.Ignite.Core.Common.JavaException: class org.apache.ignite.IgniteException: Failed to invoke proxy: there is no method 'processSomething' in type 'SomeService' with (Int32, Object[]) arguments

{code}
Service interface itself looks like this:
{code:java}
public interface SomeService
{
    int processSomething(int foo, Parameter[] parameters);
}

public class Parameter
{
    
    private int id;
    
    private ParamValue[] _values;

    
    public Parameter(int id, ParamValue[] _values)
    {
 
       this.id = id;
        
       this._values = _values;
    
    }

}



public class ParamValue
{

    private int id;
    
    private double val;

    
    public ParamValue(int id, double val)
    {
 
       this.id = id;
       
       this.val = val;
  
    }

}

{code}
And the call to the service:
{code:java}
var svc = igniteServices.GetServiceProxy<T>(name, false);
var result = svc.processSomething(id, parameters);
{code}
Now, if this is a server node then call is successful. If the call goes from the client node then we'll get the error above.

Fix in IGNITE-12823 addresses particular code execution path where the execution flow goes through PlatformServices class. Yet in this case our code goes through PlatformAbstractService. I think that the fix of casting arrays should be positioned a little bit lower in the call stack (or higher in code hierarchy) so all execution paths are covered simultaneously.
