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.
Read on if you're confused about why your mock repository keeps returning the initial collection even though you've added something to it!
