[jira] [Commented] (IGNITE-1630) .Net: Create LINQ adapter for queries.

    [ https://issues.apache.org/jira/browse/IGNITE-1630?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15173607#comment-15173607 ] 

Pavel Tupitsyn commented on IGNITE-1630:
----------------------------------------

1) Done
2) Done (except fields queries, where this is not possible)
3) Allows to specify Java type name to be used in SQL index, if the user wants to override default mapping
4) Improves performance of the fields query. Instead allocating a List<object> and then unboxing the values from it, we can read fields directly as specific types.
LINQ provider uses this method when doing fields queries. I'd like to avoid adding another InternalsVisibleTo for LINQ project, so this has to be on public API.

> SQL queries are one of the most frequently used features in data grids. And .Net comes with a very nice LINQ concept. 
> * LINQ provider should come in a separate assembly
> * Make sure that assembly is included in binary distribution
