[jira] [Commented] (IGNITE-5298) .NET: DML update via LINQ

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

    [ https://issues.apache.org/jira/browse/IGNITE-5298?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16026241#comment-16026241 ] 

Pavel Tupitsyn commented on IGNITE-5298:
----------------------------------------

{{=}} cannot be used in expression trees: {{an expression tree may not contain an assignment operator}}.
However, there is an {{Expression.Assign}}. We can provide an extension method which works like this:

{{persons.Where(x => x.Key > 10).UpdateAll(x => x.Value.OrgId.Set(7));}}
