Exception: NullReferenceException when using .Where(x => x.Field.Contains(txt)) about entityframework-classic HOT 7 CLOSED

Hello @luca-esse ,

We successfully reproduced that issue on NET Core, but it works perfectly on NET Framework.

That kind of issue normally happens when a method is no longer available in .NET Code.

It happens when the method tries to compile the current expression (
QueryParameterExpression (line: 65))

We will investigate it on Monday.

Hello @luca-esse ,

We passed a lot of time this week on this issue.

We can easily reproduce it, easily find out which line fail.

However, it's currently very hard to find out what's causing it as that happen when a compiled expression is executed.

We continue to investigate it but that one is currently harder to find that we initially though.
