How do I run my Katana based app or framework?

These instructions will help you set up an Katana based project and then author and deploy an Katana based app. For additional samples see

In VS 2012:
From the menu, click: File -> New -> Project...
In the new project dialog, select: Installed -> Templates -> Visual C# -> Web
Choose: ASP.NET Empty Web Application

Install the OWIN System.Web adapter:
Right-click on the project and select Manage Nuget Packages
Select Online, and Include Prerelease
Search for Microsoft.Owin.Host.SystemWeb" and press Install*
Also search for Microsoft.Owin.Diagnostics and install it.

Create a Startup class:
Right-click on the project and select Add -> Class...
Select Installed -> Visual C# -> Code -> Class and name it Startup.cs

Add using Owin; at the top of the file. Then add the following method in the Startup class:
public void Configuration(IAppBuilder app)

You can now "F5" to run and should see a simple welcome page running on System.Web (ASP.NET).
