DO 4.5.2

I have postsharp aspect:

[Serializable]
[AttributeUsage(AttributeTargets.Property)]
[MulticastAttributeUsage(MulticastTargets.Property, PersistMetaData = true)]
[AspectTypeDependency(AspectDependencyAction.Commute, typeof(TransactionalAttribute))]
public sealed class VirtualFieldAttribute : LocationInterceptionAspect
{
    ...
}

And when i try to use it:

...
[Field]
[VirtualField("Expression2")]
public DateTime CreatedSecond { get; set; }
...

I have exception on compilation my project:

Error   8   Unhandled exception (2.1.6.14, 32 bit, CLR 4.0, Release): System.NullReferenceException: Object reference not set to an instance of an object.

Do you have any ideas why it so?

update:

If I use OnMethodBoundaryAspect a have other exception:

Error   75  Unhandled exception (2.1.6.14, 32 bit, CLR 4.0, Release): System.NullReferenceException: Object reference not set to an instance of an object.

Any more ideas?

One Answer:

Hello Multysh,

our aspects rewrite properties in a very hard-core fashion. For example backing fields for auto-properties are removed from type completely. Probably this causes PostSharp to fail because it can't find backing field.

OnMethodBoundaryAspect should work because it operates on different level of abstraction.
