> .NET: Thin 3.0: Allow arbitrary MemberInit projections in LINQ
> --------------------------------------------------------------
>
> Key: IGNITE-18120
> URL: https://issues.apache.org/jira/browse/IGNITE-18120
> Project: Ignite
> Issue Type: Improvement
> Components: platforms
> Reporter: Pavel Tupitsyn
> Assignee: Sergey Stronchinskiy
> Priority: Major
> Labels: .NET, LINQ, ignite-3
>
> Ignite LINQ provider allows anonymous type projections:
> {code}
> query.Select(emp => new {Id = emp.Key, Name = emp.Value.Name});
> {code}
> However, it does not work with a custom class:
> {code}
> query.Select(emp => new Foo {Id = emp.Key, Name = emp.Value.Name});
> {code}
> throws exception:
> {code}
> System.NotSupportedException : The expression 'new Foo() {Id = [x].Key}'
> (type: System.Linq.Expressions.MemberInitExpression) is not supported.
> {code}
> Add VisitMemberInit overload to CacheQueryExpressionVisitor to support this
> scenario. See linked SO page for more details - there is a proposed fix as
> well.
