Conditional Travis Builds with Pull Request Labels

Manually installing Jenkins Slave as a service on Windows

Upgrading Jenkins on Windows

This procedure is the same for other operating systems, yet many windows users end up looking for an msi installer, mistakenly thinking that it should be updated in the same way as a traditional windows application. Jenkins is a java application, and is distributed in a war archive file called

xUnit tests with asp.net 5

If you've been playing around with the cross platform asp.net 5 bits (currently RC1) you will no doubt be aware of how difficult it can be to get things playing nicely together. My first task was to get a test framework configured with command line execution. To

Chocolatey Package Manager for Windows

Setting up a fresh dev box with all your favourite tools is something that every developer should automate.

Entity Framework Tests with LocalDB

Whenever i work on an Entity Framework Database First project i often think back to when i first saw Ayendes post on using sqlite for an in memory database while unit testing nHibernate [http://ayende.com/blog/3983/nhibernate-unit-testing]. It keeps things simple for testing code that works directly against

Runtime discovery of Ninject Bindings with Conventions

Ninject can figure out a lot of your interface implementation bindings with a few hints on where to look using the conventions extension. Typing out lots of explicit bindings for Ninject almost takes on the same kind of monotony that comes with declarative bindings in XML (think old style structure

Custom HttpHandler returns 404 after migrating to Vs2012

After migrating an asp.net web forms app to visual studio 2012 we started to observe some odd behaviour. The custom http handler used across the site to render images was returning a 404. The framework version had not been changed, nor had any configuration been updated. I decided to

Working with Visual Studio Database Projects

Visual Studio keeps a SQL file for each and every object in the database, and it can be cumbersome to have to maintain these manually, especially when working with tables. A more productive process is to have visual studio create a database locally for you, make your modifications in SQL

Installing TFS 2012 - Error: TF400069 A required component is not installed on the application tier

If your TFS Application Tier resides on a different instance of windows to your SQL Server, you may come across this error... The issue here is that TFS needs the SQL Server Client Tools installing on the same box, so it can manipulate the data via the Analysis Services API.

Gotcha – Unauthorised 401 on IIS

Unable to find the requested .Net Framework Data Provider. It may not be installed

This usually means that a provider specified in one of your web.config connection strings is not installed on your machine. In my specific case the offender was this… <add name="MyContext" connectionString="Data Source=|DataDirectory|myDatabase.sdf" providerName="System.Data.SqlServerCe.4.0&
