Developing Microsoft SSIS packages programmatically with EZAPI

I recently started working on a task that required me to dig into creating SQL Server Integration Services packages programmatically.  There is not a lot of info out there on this, so thought it might be beneficial for me to blog a bit as I go in case other benefit from this.

Relatively early on in my investigation I found that the internal SSIS test team at Microsoft has created and released a second level API for SSIS called EzAPI that sits on top of the native SSIS API.  Using EzAPI, you can create packages and package objects in only a couple lines of simple code, vs. trying to decipher the somewhat esoteric COM wrapper APIs for SSIS.

You can read about EzAPI on the SSIS Team Blog here.

An update was released in late 2010, which you can read about here.  This update added a lot of additional components to the API.

You can download it here (including source code and samples).
