-----------------------------------------------------------------
1) Dynamic registration does not make sense in a cluster with old nodes. These
old nodes do not have new classes anyway, and we do not have peer loading in
.NET.
I don't think it's an issue. If the user does not attempt dynamic registration,
everything else will work.
2) Ok, I'll have a look later
3) Fixed
4) I've refactored this a bit to make it clear (moved nullify call to
`PlatformDotNetConfigurationClosure.apply0`). Essentially, work directory that
is set in .NET code does not work currently. We use a dir that is set by
temporary marshaller, and there is no way to overwrite it. We should probably
fix this as a separate ticket.

> Key: IGNITE-2703
> URL: https://issues.apache.org/jira/browse/IGNITE-2703
> Project: Ignite
> Issue Type: Task
> Components: platforms
> Affects Versions: 1.5.0.final
> Reporter: Vladimir Ozerov
> Assignee: Pavel Tupitsyn
> Priority: Critical
> Labels: .net, roadmap
> Fix For: 1.7
>
>
> At present we support dynamic class registration in .NET, but they are
> written using deafult .NET mechanism. This is counterintuitive for users and
> not consistent with Java, where such classes are written in binary form.
> Proposed implementation plan:
> 1) For each dynamically registered class we must understand whether it could
> be serialized through binary or not. If not - print a warning and fallback to
> .NET.
> 2) Before writing a class we must ensure that it's [typeId -> name] pair is
> known to the cluster. If not - write full class name instead of type ID. Java
> already do that.
> 3) Last, to support backward compatibility we must be able to fallback to
> current mode with help of some boolean flag.
