The art of simplicity

After upgrading to NUnit 3.0, which became recently available, some of my tests started to fail. When I look at the test results, they all failed with the following error message: SetUpAttribute attribute not allowed in a SetUpFixture In NUnit 3.0, there are some breaking changes regarding the usage of the SetUpAttribute and the SetUpFixture.  You can no longer use the SetUpAttribute and TearDownAttribute inside a SetUpFixture. Instead you have to use the OneTimeSetUpAttribute and OneTimeTearDownAttribute. In NUnit 2.0, I had the following code: In NUnit 3.0, this has to change to: More information can be found here: https://github.com/nunit/nunit/wiki/SetUp-and-TearDown-Changes https://github.com/nunit/nunit/wiki/Breaking-Changes

Last week I blogged about the release of Open Live Writer , the open source fork of Windows Live Writer. I also mentioned that Google decided to pull the plug from the old authentication system, making neither Windows Live Writer and Open Live Writer available for usage with Blogger anymore. One week later, and thanks to the power of open source, I’m happy to say that I can write my blog post in Open Live Write again(the online Blogger editor wasn’t a pleasant experience). In the timespan of a week Martin Woodward made 3 new releases each improving the Blogger integration: https://github.com/OpenLiveWriter/OpenLiveWriter/releases So thanks Martin for this early Christmas present!

Almost every application uses data. Without this data the application is useless. So if you are a DBA, SQL specialist or developer, you should care about data and how it is stored. This makes  'Readings in Database Systems' a must read: Readings in Database Systems (commonly known as the "Red Book") has offered readers an opinionated take on both classic and cutting-edge research in the field of data management since 1988.

After upgrading an existing solution to the new build system in TFS 2015, the build failed with the following errors: The 'System.Reflection.Extensions 4.0.0' package requires NuGet client version '3.0' or above, but the current NuGet version is '2.8.60318.667'.

If you want to learn about Azure DocumentDB , Microsoft's NOSQL solution in the Cloud, go take a look at the DocumentDB Query Playground . It gives you an interactive environment to try the rich querying functionality that Azure DocumentDB offers over schema-free JSON data.

After upgrading a Team Foundation Server 2010 environment from a customer to Team Foundation Server 2015, we noticed an enormous spike in CPU and memory usage on the database server. When we drilled further into the issue, we saw the same SQL Server statement being executed over and over again: On the MSDN forums, we found some more information . This is a bug in the TFS 2015 upgrade process that only seems to exist when you upgrade from TFS 2010. A SQL script is available that solves the problem, but the issue is also fixed in TFS 2015 Update 1. So I would recommend that if you have this issue, upgrade to Update 1.

If you want to test a Microsoft product in a risk free environment, try TechNet Virtual Labs . It offers a wide range of virtual environments for testing Microsoft's newest products and technologies.     I forgot that this existed, until a colleague sent an email about it(Thanks Joeri). So if you want to play with for example the Team Foundation Server 2015 bits but don't want to put it on Azure or download and run a VM locally, just search for 'Team Foundation' and a large set of VMs and labs are available. Great stuff!
