Is it correct that without this it'll not be possible to use complex types with UseLazyLoadingProxies ?

Using both right now I have the following issue when I do a Find on a DbSet.

The foreach throws a System.NotImplementedException: 'The method or operation is not implemented.' exception in EntityMaterializerSource.cs

private InstantiationBinding ModifyBindings(ITypeBase structuralType, InstantiationBinding binding)
{
	InstantiationBindingInterceptionData interceptionData = new InstantiationBindingInterceptionData(structuralType);
	foreach (IInstantiationBindingInterceptor bindingInterceptor in _bindingInterceptors)
	{
		binding = bindingInterceptor.ModifyBinding(interceptionData, binding);
	}
	return binding;
}

Without the call to UseLazyLoadingProxies the Find correctly returns the value.

Will this be addressed before the release of the 8.0 version ?

Thanks

We had the same problem - it is impossible to use complex properties if UseLazyLoadingProxies is used in the project. Unfortunately, without fixing this problem, we cannot move to using complex properties.
