Hello
I continue to explore NH 3.0 GA + Remotion - 1.13.85 and WCF data services
I try to use projection in OData
something like
http : //localhost :
2711/TestWcfDataService.svc/TestEntities?$select=Id,FldChar10
and it does not work and generate exception with big stack trace in NH &
remotion code
the same effect i can reproduce with next LINQ query:
//This query works successfully
var l0 = ses.Query<TestEntity>().Select(p => new { p1 = p.Id }).ToList();
//This will generate same exception as WCF Data services
var l1 = ses.Query<TestEntity>().Select(p => new {p1 = (p *as TestEntity*
).Id}).ToList();
I understood that WCD DS generate strange redundant query but .....
Any idea which code responsible for this error and how this situation can be
solved?
error generated:
- <innererror>
<message>([-1] As TestEntity)</message>
<type>System.NotSupportedException</type>
