---------------------------------------
Summary: .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: Pavel Tupitsyn
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.
