System.NotSupportedException #1294

Open krenukumar opened 5 years ago

krenukumar commented 5 years ago

We are using LiteRepository . It is working fine until update to 5.0.0-alpha. Updated the calls according to the new implementation. But failing while converting predicate to BsonExpression.

Stack:

System.NotSupportedException: 'Method Contains(Func<T,TResult>) in Enumerable are not supported when convert to BsonExpression (value(Agner.Helpers.CallDataHelper+<>c__DisplayClass1_0).allstocks.SelectMany(x => x.ContactIds).Distinct().Contains(e.MobileId)).'

Hi @krenukumar, can you test with current master branch? I fix Contains method, must be fixed for your case. Will be released in next beta version
