Turning caspol -s off and Oracle ODP stops to retrieve data. New MS bug!
If you write your code using CLR 1.0 and used System.Security.SupressUnmanagedCodeSecurity attribute and your code is used by CLR 1.0 code when caspol turn off, SupressUnmanagedCodeSecurity won't be recognize from 1.1 code and exceptions will stop your code execution. That exactly what happened with Oracle ODP code that shipped compiled with CLR 1.0 version even for CLR 1.1 version. Meanwhile Oracle send us ODP version compiled with CLR 1.1 and every thing work great.

MVC and ASP.NET forms part II
Well, I was very happy with the adjustment I add to maverick until I check page postback. This check failed due to inner implementation of maverick. So I think my search for MVC framework that support Postback ended without any results. I understand the conflict between classic MVS and postback applications that required preserving data form page call to call. I think that the main reason for that clash is porting of Java MVC framework to .NET, instead of building MVC framework suitable for .NET.

Where to draw the line between attributes and XML.
It's not the first time that I have that feeling after long code review that programmers don’t know where to draw the line between using attributes as declaratives or using XML and interfaces to achieve the same goal. While it's true that attributes are more clean way to declare your intension about certain class then using virtual classes or interface it's not always the right choice. I didn’t see it often but I saw programmers using attributes in places where interfaces is needed due to the need to implement interface by declaring class. What I've seen often is using of attributes where XML are more suitable. Well maybe its just point of view, and anyone got its own, but I see clear line between them. Attributes should be use just for declarative purpose of the programmer (I want logging or auditing in that function please). XML should be use for sys admin usage like setting logging on/off for a given system. Moreover, XML setting should override attributes setting if they clash.

Checked exception and Attributes
I read and it looks that using attributes to declare function exceptions and validate exception handling in compile time could solve that problem. Amit On and I play around with that concept and it works fine. The problem is that MS doesn't implement such mechanism so we can't handle and enforce exception handle of CLR functions. Any Microsoft or others comments?

Disable viewstate
As I wrote ASP.NET always write Page hash key to view state. To disable this behavior you need to override page SavePageStateToPersistenceMedium and LoadPageStateFromPersistenceMedium functions and to disable the default Page behavior by not calling page base class. Those functions persist viewstate data in hidden field.

Smart client and Integration aspects.
The world is going toward integration between systems (not applications). I personally spend time on IT aspects of companies merging and acquisitions. Usually merging and acquisitions process emphasis Integration problems. Integrating systems to operate as single system or to enable one system to gain other system data and logic is not simple task. This integration task becomes harder if those systems developed with different technologies and nightmare if each system develops for specific operation system. Acquisitions process emphasis Integration problems but Integration problems may raise on other scenarios, such as your company wants to share data and knowledge with other companies around the glob.
