Share Object to all Users of mvc Webapp

My web App prepares out of a db for one or two minutes a specific and read-only object list, once only when IIS starts. This does not change an开发者_JAVA百科y more unless the admin triggers recreation by a specific URL.

The Interface of the objects looks like this:

public interface IProductsRepository {
    IQueryable<Row1> ProductItmes { get; }
    IQueryable<Row2> ProductLegItems { get; }
}

I am now not really sure where i put the object so it is accessible from any controller. Should i put the load method to protected void Application_Start() as a static object? What is the best approach?

you need to use a dependency injection framework here so you can instantiate this one and pass it into all of your controllers. This doesn't come out of the box with asp.net-mvc but you can find a number of options that will do the trick like castle windsor or autofac

This may or may not meet your needs but Castle Windsor allows you to specify how many instances a component (like a data repository) will have. I personally had a typo when working with this (lifesyle instead of lifestyle) that resulted in the data repository persisting after a post without my initializing it.

A good place would be the the Cache. You can load the Cache on Application_Start()

You can store it in Application object, but you should inject it into Controller. You shouldn't reference directly Application object, because this will make your application less testable. I use Ninject (http://ninject.org/) for this purpose.
