Hi to all. I'm developing a ASP.NET MVC 2 web application. So far, I managed to define access rules for every controller function, using "RequiresRole" attribute. Suddenly, this way of defining access rules stopped working (now every user can invoke any of the controller methods). :S. I tried debugging, and it seems that user-roles are...
I've noticed in Visual C# 2010, whenever you change the target framework version away from the default 4.0 client profile (and even if you change it back afterwards), the IDE creates a. config file that it clearly thinks ought to be shipped with the program.

Hello I have a Win Mobile 6.0 .NET CF application that uses a reference to a WebService in order to call web methods on it.

I was looking at Microsoft for a setup package for .NET 1.0 that includes SP3, so I don't have to install the framework first and then the service pack. But I didn't find any. Then I looked for the newer versions of the .NET framework and noticed that service packs are always an extra download/setup. It seems there is no full setup incl...

One simple way to add some configuration is to define a configuration section which is not much more than some object that can be (de)serialized based on the XmlSerializer classes. Now, XAML is at its heart more or less a hierarchy of objects but provides things like naming of elements, binding, etc. Has anyone ever used XAML outside i...

On our demo machine (great!), when the internet is not connected, all connections to the server fail. I do have two errors in my logs: The I/O operation has been abor...
