2011-02-17T18:23:00.007+11:00

I have a bit of SVN trouble today. Ended up deleting all .svn folders so I could re-add them to perform my commit. Therefore I am going to quickly share a powershell script that will delete file/directory base on a match string. Note that it deletes hidden dir/files as well.

I have given my first talk at SDDN Melbourne about Pivot from Microsoft Labs. I was really excited to be given a chance to speak at the local user groups.

CRUD Snippet for RIA Domain Service

2010-09-14T14:04:00.014+10:00

I would like to briefly share my new snippet - CRUD for Domain Services. Code your domain operations in 2 seconds! CRUD stands for Create, Read, Update and Delete. To provide access to RIA consumers with a particular entity, you need to create at least one domain operation (e.g. Query) to be able to code against the entity on the client side (e.g. Silverlight). I have got tired of doing

Before we start, let's understand why including view injectable controls inside child windows can be tricky. It all comes down to the child windows do not get a hold of the region manager.

MVVM, Prism, Unity, Blendability?!

2010-03-17T22:02:00.010+11:00

In the previous post we mentioned MVVM: Model - View - View Model to separate the XAML and code through binding. Today we are about to put Unity and Prism into mix. For the past few weeks, I have been digging around to find out how we would approach our solution with all these goodies out there with a check list in mind. Firstly, we love our designer, so we definitely want to keep our XMAL

Introducing MVVM - Model View ViewModel

2010-03-01T20:09:00.011+11:00
