I would like to upgrade c# code to use latest NEST 2.0 version, but I am having difficulties because of the breaking changes in the latest version:

> <https://github.com/elastic/elasticsearch-net/blob/a5789c70bb84f521ca710f379a8da3b9ff80b919/docs/2.0-breaking-changes/nest-breaking-changes.md>

What are the plans to update documentation on this location?

[https://nest.azurewebsites.net/](https://nest.azurewebsites.net/)

I am using Object Initializer Syntax and I am looking for examples on how to rewrite code because following objects are not available anymore: RootObjectMapping, PropertyNameMaker, StringMapping and many others..

Thanks,  
Andrew

Bumping up this question  
I've got similar problem as Andrew.  
I was using code base mapping and whole object are gone.  
I've posted question on [stackoverflow](http://stackoverflow.com/questions/35556738/code-base-mapping-in-nest-2-0) but not much response.

Thanks
