  November news   The last few months have been exciting here at eXpand. First and foremost the number of you that are contributing to the project has shot up which is great news for all of us! Also (as some of you may have noticed) we have earned ourselves a place in the DevExpress start menu. There has been a flurry of activity on the development side too, as a result we are pleased to offer a host of innovative new features. Finally eXpand is now registered at http://nuget.org/ so it can be accessed via Visual Studio. Contributors! First of all we must all say a big thank you to everybody that has been contributing to eXpand in any way. We appreciate your continuing love and support whether in the form of forum posts, code submissions, user suggestions or simply spreading the good word about eXpand! Our community is very healthy right now, I am proud of the fact that eXpand users are collaborating more than ever and sharing their ideas and stories. Of course at the same time we must thank DevExpress for their steady support... 21-11-2011, 04:06 από A.Bekiaris's .Net / XAF Blog στο A. Bekiaris's Blog

  Using ASP.Net web services in Silverlight 4 applications In this post I would like to present in detail how we can consume .asmx web services from a Silverlight 4 application. Silverlight supports and “recognises” web services in a similar way that ASP.Net applications can “talk” to web services. One might say that .asmx web services are considered by Microsoft legacy software. I will not disagree with that. Sometimes we do not have the luxury (time or budget) to create the services from scratch. It is very difficult to convince your boss or client to create a WCF service that does something when the functionality already exists in a web service (.asmx). So if now, I have the chance to write a whole Silverlight application from scratch I would not use .asmx web services, I would use WCF. But as I said before we have to use and maintain legacy code.

  Δημιουργώντας ελληνικές εφαρμογές στο Windows Phone Σήμερα μου ανέφερε ένας γνωστός ότι η ελληνική του εφαρμογή “κόπηκε” λόγω γλώσσας κατά τη διαδικασία του ελέγχου από την ομάδα του Windows Phone marketplace, παρότι είχε επιλέξει να γίνει publish μόνο στο ελληνικό marketplace, είχε βάλει ελληνική περιγραφή, ελληνικό user interface κ.λ.π. Τι συνέβη; Ο λόγος που κόπηκε είναι γιατί το default language της εφαρμογής του ήταν Αγγλικά. Για να το αλλάξετε αυτό, θα πρέπει να κάνετε δεξί κλικ στο project, properties, assembly information στην καρτέλα application και από εκεί να αλλάξετε το neutral language της εφαρμογής σας, θέτωντας το σε ελληνικά. Με αυτό τον τρόπο, η ελληνική εφαρμογή σας θα φαίνεται ότι υποστηρίζει την ελληνική γλώσσα και θα γίνει δεκτή στο marketplace!   Διαβάστε περισσότερα »... 08-11-2011, 21:46 από Scenes From A Developer Memory στο Scenes From A Developer Memory

  A scripting language for your (web)app with DLR or Roslyn Well, this subject always excited me! The fact that you can provide at your executable, a programming language (script) that the user can use to interact with your application is something amazing. In this post, we see how this is possible by using the Dynamic Language Runtime (DLR) and IronPython, and then see whether the services provided by the Roslyn project can help as achieve the same result with C#. The whole idea behind providing a scripting language at runtime may find the following three applications:   You implement a DSL (Domain Specific Language) meaning that you want to provide to your end use an expressive tool to specify his behavior in a specific application domain. In this case you expose some parts of the information held in your application in the form of methods that the user can use in his scripts to achieve the desired result. You want to be able to change a specific behavior without having to recompile the whole application or in the case where you use the same executable in multi-tenant... 31-10-2011, 13:14 από C# and .NET Tips and Tricks στο C# and .NET Tips and Tricks Δημοσίευση στην κατηγορία: ASP.NET MVC, DLR, Roslyn, Scripting
