Multiply Dsl points of view

Pascal — Tue, 13 Jan 2009 15:20:00 GMT

DSL Tools are becoming more popular everyday and naturally questions are increasing in volume on MSDN forums dedicated to Visual Studio Extensibility. However, this fact is not the only reason to advocate that DSL Tools gained in maturity. It is better for now to focus on a recurring request in the form of multiple views of a single diagram. This is mainly derived from the fact that models implemented using DSL Tools are getting bigger and bigger by the day and it becomes quickly important to be able to occult some aspects of the model while putting the emphasis on others. The goal of this article is to present a solution to implement such functionality....(read more)

Let your community site leverage Windows Live

Tony — Mon, 03 Nov 2008 07:00:00 GMT

kjlkjMost web sites require managing users from personal details to authentication. Event though, ASPNet provides some tools ease this process with a Sql Server backend database. This can be tedious to manage and implies a responsibility to keep personal data safe furthermore people put some time and effort into filling in their Windows Live Id profile information. Of course some web sites make their business on having a huge user database. However community web sites such as netfxfactory does not gain any added value from managing its own user database. Various blogs and papers on the web explain how to leverage Windows live authentication mechanism to validate a local user (see here here and here). They mostly let someone associate its web site account with his Windows Live Id however it’s name, dob, email etc… are still managed localy by the web site (this is the functionalities offered by the Memebership provider offered with the Windows Live SDK). Only the authentication mechanism is leveraged here. The goal of this article is to go one step further and externalize as much as possible the user management. Managing locally user’s data requires an extra effort from the user to keep his information up to date. We will demonstrate a solution using Windows Live based on a custom aspnet membership provider used to pull out information from Windows Live such as User info but also his contacts info. This is a first step towards S+S as promoted by Microsoft. Most web sites require managing users from personal details to authentication.

Tony — Wed, 04 Jul 2007 14:07:00 GMT

As outlined in the first part of this article, referencing services greatly extends their visibility and promotes their capitalization.

An effective way to access WCF services

admin — Wed, 24 Jan 2007 10:33:00 GMT

WCF offers a very seamless way to handle service end point configuration. This is done via both the service configuration file and the client's. Specially in an intranet and even more in development environment, where you have to take care of both the cook and his clients, maintaining each and every client up to date with the latest service config can be quite tedious specially if you have a large number of clients to update. One way to overcome this problem is to retrieve the service's metadata in order to infer the services endpoints configuration instead of deploying via configuration file on each client. ...(read more)
