Hosted TFS, now called Visual Studio Online (VSO), has a new way of writing build processes called Build vNext. Agent tasks are the building blocks of processes and you can supplement the built-in ones with custom build tasks defined in JSON that use targets written in node.js or PowerShell. Jason Crease shows how to develop custom build tasks for building, testing, publishing and synchronizing databases.… Read more

Metrics – A little knowledge can be a dangerous thing (or ‘Why you’re not clever enough to interpret metrics data’)

0

At RedGate Software, I work on a .NET obfuscator called SmartAssembly. Various features of it use a database to store various things (exception reports, name-mappings, etc.) The user is given the option of using either a SQL-Server database (which requires them to have Microsoft SQL Server), or a Microsoft Access MDB file (which requires nothing). … Read more

Breaking through the class sealing

0
5
Do you understand ‘sealing’ in C#? Somewhat? Anyway, here’s the lowdown. I’ve done this article from a C# perspective, but I’ve occasionally referenced .NET when appropriate. What is sealing a class? By sealing a class in C#, you ensure that you ensure that no class can be derived from that class. You do this by … Read more

Order of Construction

0
0
  For me, inheritance is often a headache.  In particular, in what order is everything initialized?  Consider this short C# program.   It creates an instance of Dog, which derives from Animal.  Both Dog and Animal have an instance constructor, a class initializer (aka a static constructor), an instance variable, and a static variable.  There are … Read more
