Web API is a feature of the ASP .NET framework that dramatically simplifies building RESTful (REST like) HTTP services that are cross platform and device and browser agnostic. With Web API, you can create endpoints that can be accessed using a combination of descriptive URLs and HTTP verbs. Those endpoints can serve data back to the caller as either JSON or XML that is standards compliant. With JSON Web Tokens (Jwt), which are typically stateless, you can add an authentication and authorization…Continue reading

At the time of writing, beta 1 of Entity Framework 6.1 has recently been released. This is mostly a maintenance release, however, there are several new feature of note, including the ability to add indexes using a new data annotation when developing using the code first approach. Add indexes using the Index attribute To add an index, simply add the Index attribute as required; A quick look in SQL Server Management studio reveals that the index has been added for us. The key created was non…Continue reading

T4 (Text Template Transformation Toolkit) has been around for a while now… its been a part of Visual Studio since the 2005 release. In case you don’t know, T4 can be used to automatically generate files based on templates. You create a text template, which is then transformed (interpreted) by Visual Studio into a working file. T4 can be used to create C# code files, and indeed it forms the basis of the current scaffolding templates you have probably used when creating ASP .NET web applications…Continue reading

It has traditionally been quite painful to interact with any part of the Microsoft Office product family from a C# application, but thanks to the introduction of dynamics and optional parameters over recent years, the process has dramatically improved. Step 1 - Prerequisites and Assembly References Before doing anything, it is important to note that you must have Microsoft Office 2013 installed for this to work. Seems obvious, but, its still worth mentioning. You also need two references; The…Continue reading

I’m not afraid to admit it. I can’t be the only one who has been confused by IQueryable when working with Entity Framework or LINQ to SQL. When using the web to research the topic, I have seen many conflicting blog posts and contradicting answers on StackOverflow. I have read various posts on MSDN about the subject, and I find them difficult to understand and incomplete. I seek to at least attempt to clarify the subject a little with this post. Entity Framework has become such a powerful object…Continue reading
How to fix 'Project failed to build' error when adding an Entity Framework migration (add-migration)
06 September, 2013.
I recently spent several hours tearing my hair out try to figure out why Entity Framework was preventing me from adding a migration to my project. I made some very simple changes to my existing model (I’m developing using the Entity Framework Code First approach) and when trying to add a migration, I was presented with the following error message; But how can this be? For you see, my project does build… My project not only builds, but it runs and works just fine … (up until the point where…Continue reading

I’m assuming that you have seen the light, and that you are sold on the benefits (and indeed the drawbacks) of unit testing. I have read literally dozens of blog posts, watched many videos, and read several books about unit testing and the various approaches and frameworks. I have worked with several of these frameworks in both small and enterprise level applications, and I have found that (in my opinion at least) NUnit and Moq are great for helping to get simple tests written quickly and to a…Continue reading

This short post is a follow on from an earlier series of posts that discussed how to achieve MVVM purity in WPF using Structure Map. You may want to check out those posts first before reading this post. However, if you just generally want to know how to do setter injection using Structure Map, you are in the right place! A Scenario It is very common in modern applications to have a repository that does the job of retrieving and saving data from/to your database. Your repository may look like…Continue reading
