Hi Recently i had to work with Windows workflow foundation for some conceptual demo or proof of concept demo. During development time i faced a strange problem. some of the windows workflow tools are not showing in tool box.

 

 

I try to reinstall the workflow extention for Vs2005 but the problem remain. if you see care fully i can not drag and drop a code activity from the tool box. That was a little but disturbing … then i reset the tool box. and every thing got back on line again. i just right click on the tool box a popup menu come up which has a reset menu item.

 

 

Some time in some other extention of vs this thing can happen. Dont forget to reset your tool window.

Recently we developed a spacer project. Goals for this project is to learn new technologies of Microsoft. Microsoft is developing the new generation of windows programming and web programming environment. As part of this evolution, Microsoft developing four major technology

1. Windows presentation foundation.
2. Windows Communication foundation.
3. Windows Work Flow Foundation
4. Windows Card Space

In our project we covered two technology that is WCF ( Communication Foundation ) and WPF (Presentation foundation). And we used recently released customer preview that is JULY CTP. In my point of view windows presentation foundation is a Break through in windows programming environment. Same interface is serving the UI for both web and windows. Pretty good. Event thought the performance is a good and big issue. I hope Microsoft is going to cover the lacks that WFP has in its Release product.

WCF ( Communication foundation ) this "the" future web service or inter-process communication service. or we can call the service of taking to every one. very well organized and well designed that can be used in local machine as windows service and also in web service.

More of .net frame work discussion will be listed in my blog.

But Buttom result is that i like the idea of both WPF and WCF.
