OwinStartup not firing

OwinStartup Not Firing: A Troubleshooting Guide 🚀

Are you facing the frustrating issue of your OwinStartup configuration code not firing anymore? 😫 Don't worry, we've got your back! In this guide, we'll walk you through some common issues and provide easy solutions to get your code back on track. Let's dive in! 💪

1. Double-check the OwinStartup Attribute 👀

To ensure that the basics are properly covered, confirm that you have the OwinStartup attribute assigned correctly in your code. It should look something like this:

[assembly: OwinStartup(typeof(WebApplication.Startup))]

Make sure there are no typos or missing references. If your attribute is already correct, move on to the next step.

2. Check the AutomaticAppStartup Setting 💡

One common cause for the OwinStartup code not firing is having the owin:AutomaticAppStartup appSetting set to false. To fix this, update your web.config file and add or modify the following key-value pair:

<add key="owin:AutomaticAppStartup" value="true" />

This ensures that your application automatically starts up with Owin.

3. Specify the appStartup Setting 🔧

If the above step didn't help, try explicitly specifying the owin:appStartup appSetting. This tells Owin which class to start the application with. Add or modify the following key-value pair in your web.config file:

<add key="owin:appStartup" value="WebApplication.Startup" />

Ensure that you replace WebApplication.Startup with the correct namespace and class name for your Startup class.

4. Verify Package Version Compatibility ⚙️

Sometimes, upgrading NuGet packages can lead to unexpected issues. In this case, try reverting the Microsoft.Owin.Security packages to the previous version (2.0.1). Make sure to update the references in your project accordingly.

5. Watch Out for Resharper Modifications 🧐

Be cautious while using tools like Resharper, as they might unintentionally modify your project settings. In this case, it's possible that Resharper removed the reference to Microsoft.Owin.Host.SystemWeb while removing unused references.

6. Still No Luck? 😕

If none of the above solutions work, it's time to do some detective work. Review any recent changes you made to your code or project configuration. Sometimes a simple oversight, like a missing assembly reference or incorrect namespace import, can cause this issue.
