[jira] [Commented] (IGNITE-3325) .NET: LINQ Take method does not work within CompiledQuery

["Pavel Tupitsyn (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/IGNITE-3325?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15334040#comment-15334040 ] 

Pavel Tupitsyn commented on IGNITE-3325:
----------------------------------------

There are other corner cases, like using same lambda argument twice in the query.
To solve all the limitations once and for all, we should change the API from {code}Compile(Func<T1, IQueryable<T>> query){code} to {code}Compile(Expression<Func<T1, IQueryable<T>>> query){code}
This will allow to analyse expression in full detail and substitute arguments in any order, and allow constants.
