> 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.
