API 2012 Support: External Command Creator/Wizard

As announced previously, Revit Addin Wizard (RevitAddinWizard) and its various wizards, coders and widgets have supported Revit API 2012 additionally natively and seamlessly.

In this post, let us have a look at the External Command Creator/Wizard. Its wizard pages are the same as before. The only difference is that for Revit API 2012 addin projects the Regeneration option has only Manual for choosing.

Other settings, options, UIs and the auto-generated code are the same as before and compatibility with Revit API 2011 is perfectly maintained.

Here is the auto-generated external command class:
