------------------------------------------
Failures unrelated.
> .NET: Avoid binary configurations of Ignite Java service params and result
> when calling it from Ignite.NET
> ----------------------------------------------------------------------------------------------------------
>
> Key: IGNITE-10075
> URL: https://issues.apache.org/jira/browse/IGNITE-10075
> Project: Ignite
> Issue Type: Improvement
> Components: platforms
> Affects Versions: 2.9
> Reporter: Alexey Kukushkin
> Assignee: Nikolay Izhikov
> Priority: Major
> Labels: .NET, sbcf
> Attachments: IGNITE-10075-from-2.9.0.patch, MyTest.cs
>
> Time Spent: 2h 10m
> Remaining Estimate: 0h
>
> Presently if there is an Ignite Java service taking parameters of complex
> (composite) types and returning a result of complex type then all the complex
> types must be explicitly specified in the binary configuration.
> We need to enhance Ignite not to require binary configuration assuming that
> we use the same type, package/namespace and field/property names on both the
> .NET and Java sides (or provide a custom name mapper for relaxed naming
> conventions).
