  • Team Foundation Server 2012 build notification using ASP.Net Web API

    For the last three years I have helped a financial company with a business critical financial system. I have the role as an architect and coach when it comes to system design. I also spend times to make the team work more efficiently, to release new features with high quality, and maintainable code faster. So the last months I have spent a lot of time with a Deployment Process, to see how we can use Continuous Delivery. We use Visual Studio 2012 and Team Foundation Server 2012 (TFS) as our configuration system. We use gated check-ins (The goal is to use branch by abstractions, so the team work against one mainline only, to remove the "merge hell"). Even if we use gated check-ins we had to disable some acceptance tests because the time it takes for them to run. Instead we use a build that runs at lunch time and one at the night to include the acceptance tests (Those needs to be observed by the team). So far TFS have worked perfect, both for Gated check-in and Continuous Integration for the mainline. We also use TFS for a "push deployment" to our internal test and UAT environment. Everything is automated. We haven't yet "enable" the "push-deploy" against our production environment yet.


  • ASP.NET Web API Exception Handling

    When I talk about exceptions in my product team I often talk about two kind of exceptions, business and critical exceptions. Business exceptions are exceptions thrown based on “business rules”, for example if you aren’t allowed to do a purchase. Business exceptions in most case aren’t important to log into a log file, they can directly be shown to the user. An example of a business exception could be "DeniedToPurchaseException”, or some validation exceptions such as “FirstNameIsMissingException” etc.


  • Log message Request and Response in ASP.NET WebAPI

    By logging both incoming and outgoing messages for services can be useful in many scenarios, such as debugging, tracing, inspection and helping customers with request problems etc.  I have a customer that need to have both incoming and outgoing messages to be logged. They use the information to see strange behaviors and also to help customers when they call in  for help (They can by looking in the log see if the customers sends in data in a wrong or strange way).


  • Fluent-API to add ActionFilters to Controllers – ASP.NET MVC Part 2

    I’m working with my Fluent-API for adding Action Filters to Controllers and Action Methods. In my previous post, I created a new instance of each Action Filter and add it to an Action Method or Controller. Based on how the Action Filters are often implemented they don’t or shouldn’t keep any state, so in that case I don’t need to create a new instance of the same Action Filter with the same configuration for each Action Method I want to add it to. I also want to have an option to have a better overview of which Action Filter is added to which Controllers and Action Methods. I have added to methods, AddFilterToControllers and AddFilterToActions:

                .AddFilterToActions(new HandleErrorAttribute(),
                                    c=> c.About(),
                                    c=> c.Index());
                .AddFilterToActions(new OutOfMemoryException(),
                                    c=> c.About());
                 .AddFilterToActions(new HandleErrorAttribute() { ... },
                                    c=> c.MyMethod());

    The code is not yet available due to some more changes and testing.
