Development

The wiki already has a number of useful pages of content that demonstrate how to develop modules:

• Module Development
• Creating a DotNetNuke Module Project in Visual Studio
• Customizing a Visual Studio Project Template
• DotNetNuke Development Controls
• Setting up your Module Development Environment
  

In addition it's highly recommended you consider the module development templates discussed in this blog . The blog entry also links to a short video explaining how to use these templates.

Packaging

There are a number of ways to do packaging for modules such as
Automated DotNetNuke Module Packaging MSBuild and Automated Module Packaging for DotNetNuke, as well as using the built in UI to create packages.

There is also extensive documentation on the Manifests format and all of it's capabilites available.

Do's

• Do use DotNetNuke.Common.Globals.NavigateURL when generating links
  

• Do have your module controls inherit from DotNetNuke.Entities.Modules.PortalModuleBase
  

• If your modules use jQuery, please use the relevant framework calls to ensure only one copy if loaded.
  

Don'ts

• Don't use Session variables. Session variables can cause issues when running in webfarm scenarios. Neither DotNetNuke or any of the core projects use session variables for this reason.
  

• Don't trust user input - if you need to accept user input you should use the PortalSecurity InputFilter methods to filter the content as required.
  

Performance

• Consider setting the following attribute in your web.config file to improve speed for recompilation
  

  <compilation ... batch="false"> ...</compilation>
