I'm just getting started with VS 2005. One of the questions I have is regarding the App Code folder. I write my VB class code and drop the .vb file in the App Code folder. Then in my Webform .asp page I can access my classes. My question is how does the webform know about the classes in the App Code folder? I thought the class code in the App Code folder would get compiled into an assembly (.dll) and this would be placed in the bin folder. However, I have not created a bin folder and no .dll file has been created by VS. Is there an assembly being built behind the scenes which contains references to the classes I create in the App Code folder? Which brings me to my next question. If I have a .dll file containing classes, do I simply need to create the bin folder, add the .dll to the bin and then I can directly reference the classes in my .aspx page?

 Thanks for any clarification on the App Code, bin, and referencing classes questions which seem to always be lingering.

ASP.NET 2.0 does dynamic compilation. Any code in the App_Code folder is compiled into the App_Code.dll assembly. This Assembly is created during the Application Startup.

That is pretty much it.

As far as using already existing Assemblies, yes you create the bin folder and put your assemblies in there, then you can reference them.

So if I work on a .VB file in the App code folder and I modify it locally, then want to make the changes availabe on my remote server, do I only need to FTP the .VB file and not worry about moving around the App_Code.dll assembly?

 Thanks
 

Do you have to distribute any vb codebehind for my aspx pages? With the project as well?
