• please we need php replacement on linux.

  - by diamandiev

  PHP is just awful but atm the only cheap server technology available. If you want free hosting you are stuck with php. If you want cheap hosting too. Windows hosting is like 3x the pice. It's amazing how much effort people put into executing a task in php while they could this 10 times faster and better with a real language/server platform (asp.net). Just my 2 cents.

• Can I integrate many sources into one RSS reader?

  - by BenAlabaster

  I'm looking to integrate a bunch of RSS/ATOM sources into a feed for our intranet. This is outside my usual realm of work so I've had very limited exposure to this. I'd like to integrate all the feeds into a single reader such that all the news items are in chronological release order. Is this doable? Do I need a special component? Or can I make the ASP.NET integrated components do all this simply enough?

• Ninject and Custom Controller Factory

  - by Baddie

  I'm using MEF with ASP.NET MVC as demonstrated at http://blog.maartenballiauw.be/post/2009/06/17/Revised-ASPNET-MVC-and-the-Managed-Extensibility-Framework-(MEF).aspx. When I try to use Ninject, it seems that nothing gets injected. I did some debugging, and when I reverted to the original controller factory the injection worked. What needs to be changed, or what does Ninject need in terms of controller factories for it to work?

• What is the recommended approach to add static subdomains to a website?

  - by shg

  I would like to create a few static subdomains like: mycategory.mydomain.com in a rather small website and would like it to point to the folder: mydomain.com/mycategory without showing such redirection in browser address bar. What is an easiest way to achieve it? I can do it in either IIS settings, asp.net, C# code, etc I guess there are better ways then creating a few separate Sites in IIS - one for each subdomain.

• Dispose a Web Service Proxy class?

  - by Matt

  When you create and use a Web Service proxy class in the ASP.Net framework, the class ultimately inherits from Component, which implements IDisposable. I have never seen one example online where people dispose of a web proxy class, but was wondering if it really needs to be done. When I call only one method, I normally wrap it in a using statement, but if I have a need to call it several times throughout the page, I might end up using the same instance, and just wondered what the ramifications are of not disposing it.
