The below is an involved problem, I've done a great amount of research, but have been unable to solve it thus far. I'm happy to find either a solution or a workaround.

I have a class 'Data' that uses a getter to access some array. If the array is null, then I want Data to access the file, fill up the array, and then return the specific value.

Hello, I've been doing a bit of research regarding action filters and wondered if there was a way to add them programmatically to controllers?? To give some context, I'd like to add a logging filter if logging is configured in the web.config, otherwise I don't want the filter to exist in the execution chain of each action method. I ap...

There it sits...open...and empty, but what next? I can add my tables to a datas...

Is it possible to host custom data on self-hosted HTTP-configured WCF services, such as custom HTML or XML files, without involving IIS? I’m speaking of a ServiceHost instance that instantiates its own EndPoints/listeners.

I'm coming from the LAMP world, where the "cache everything" mentality is prevalent. Everything is put in memcache. I'm starting a new project with ASP.NET MVC and SQL Server.
