A quick rundown of the released files

N2 Source Code (runtime + examples + templates): The source code of N2, the templates project and the examples. If you download this project you need to run Prepare_Dependencies-vs2008.bat located in the src folder to copy dependencies such as n2.dll and the /edit directory files to the examples and to the templates project. To try quickly don't download this.

Simple Examples (compiled runtime + example code in C# and Visual Basic): Two very basic examples implemented with C# and Visual Basic.NET. This is useful to learn that you can use VB or if you find that the templates contains too mutch fluff.

Templates Examples (compiled runtime + compiled templates + example project): This is the example that we'll use in the startup guide. The templates is a proposed implementation of a CMS with features such as news, rss and calendar. The templates code is compiled and included in the project and there's an example project where we can implement additional functionality.

Compiled Runtime (for upgrade / do it yourself): This zip contains some dlls and /edit folder used by N2. Useful for upgrading an existing site. 

Compiled Templates (Templates + Runtime + Express DB, no code): A compiled version of the templates. This along with the compiled runtime is included in the templates example. 

Parts Example (drag & drop): A minimal example using the drag & drop features in n2.
