Hi Jb,

I will first make a script that can reliably hit the bug in relatively short
time. Currently, I hit it once or twice a day on ~100 application restarts.

Then I will try to remove asp.net, replace nhibernate with empty library, etc.

First, I suspected runtime handling of application domains, as runtime
sometimes crash when xsp tried to load changed DLLs into new application
domain. Since then, I made sure xsp is always restarted, but the LINQ crash

I will report back when I have more info.

I just hit the most common exception:

System.ArgumentException: Can not assign a
System.Runtime.CompilerServices.ExecutionScope to a
  at System.Linq.Expressions.Expression.CheckLambda (System.Type delegateType,
System.Linq.Expressions.Expression body,
System.Collections.ObjectModel.ReadOnlyCollection`1 parameters) [0x00000] 
  at System.Linq.Expressions.Expression.Lambda[Object]
(System.Linq.Expressions.Expression body, IEnumerable`1 parameters) [0x00000] 
  at System.Linq.Expressions.Expression.Lambda[Object]
(System.Linq.Expressions.Expression body,
System.Linq.Expressions.ParameterExpression[] parameters) [0x00000]
