> .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: 2.6
> Reporter: Alexey Kukushkin
> Assignee: Pavel Tupitsyn
> Priority: Major
> Labels: .NET, sbcf
> Attachments: MyTest.cs, ignite-10075-vs-2.8.patch
>
>
> 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).
