Sample project (repro)
See attached sample project + screen capture.
Screen capture is inside the sample project at the root.
In the sample project, add a breakpoint on tt1 line. Try to display the value of SomeValue. Result: "unknown member".
The reason that SomeValue is an unknown member is because Model is null.
You need to initialize 'Model' first.
I guess the error could say that Model was null instead of saying that SomeValue is an unknown member.
Well in this proof project this is true, but i will prove you this happens also on non null values, as i hit this bug everyday.
I've committed a fix that reports "Model is null" instead of saying "Unknown member: SomeValue"
Do you have a test case where this happens for non-null values?
