问题 I created a a Visual Studio 2015 RC solution as follows: Project global.json Source MvcProject MvcProject.Test MvcProject.Test is a class library where I created a Test.

问题 I'm trying to hook into the ExecuteAsync() call that renders a razor page using my CUSTOM view page (that inherits from RazorPage ). In the RazorPage class there is this abstract method: public abstract Task ExecuteAsync(); That method gets called within the output generated by razor when parsing a .cshtml file (view). Obviously, I cannot just override it because mine would never get called from the view that gets generated, which also overrides this method (though that would be nice, and

问题 Let's say I have a class called MySiteConfiguration in which I have a bunch of, you guessed it, configuration data. This data will not change over the course of the application's runtime after it has been loaded. My goal would be to construct an instance of this class at startup and access it from my controller actions. I do not want to construct the class more than once, as this should not be needed. To do this in WebApi 2 for instance, I would: Instantiate the class in my application start
