Upgrading to NBusiness 2.1

I finally spent some time last night updating this blog site. I still have a few things that I want to do but I got some of the big things out of the way. The first big one was upgrading to NBusiness v2.1, actually it was pretty easy to do but I wasn’t sure how it would work out.

For anyone out there running 2.0.1 and thinking about upgrading to 2.1 I’ll try to list some issues you are bound to encounter. The first one is the change from using the static CreateNew() method to using constructors. so if you have code like this:

Blog blog = Blog.CreateNew();

You will need to change it so that it looks like this:

Blog blog = new Blog();

Much better if you ask me! Also the old create new methods will still be generated but it will give you an obsolete error message so you can find and change them easily. You may also have to change references to NBusiness in your website, i had to alter a web.config file that had version information in it. Other than that I had to run the sql stored procedures it created on my new site to get it to work which is fine.

Also there is one big problem I encountered and that is that the scripts will generate sibling relationship tables and scripts and keys at the bottom of “complete.sql” not at the top with the rest of the tables! Which means if you try to run just the scripts be sure to search for ALL of the table drop/create scripts because I accidentally dropped my BlogsTopics tables when upgrading. Which turned out to be ok because I wanted to redo them anyway (I had too many useless topics) but it could have been really bad in a bigger site.

I’ll probably make NBusiness v2.1 available as the primary download on codeplex later today (you can get it right now from the planned release section).

The biggest new feature of NBusiness 2.1 is the ability to use some generated objects to create dynamic sql. So when you go to create custom fetch methods its much faster than the current system. The other features are listed on the download page.
