I stumbled across the Dynamic LINQ Library today and can't figure out why more people aren't talking about it.
It's an awesome little library that allows you to dynamically generate LINQ expressions from strings, which is perfect for things like sorting collections by object property names passed as querystring parameters to web api controllers, it even allows you to sort by child object property names!
I got an email from a client today about an error happening in an application that I'd built with ASP.NET Web API 2.1. At first I thought they must be mistaken or doing something wrong on their end because their weren't any errors being reported by ELMAH which I'd configured in my WebApiConfig.cs file using the ElmahHandleErrorApiAttribute filter.
This post shows you how to create a custom authorization attribute which allows you to pass in a list of enums as parameters to restrict access by role. I'm using this attribute on the controllers of a RESTful Web API built with ASP.NET WEB API 2.
