No assembly found containing an OwinStartupAttribute
Aug 24, 2020 08:34 AM|lisa2020|LINK
Hi
I've been working on some code, and i'm getting the following error.
I've found some similar problems on the web so I've added the following in my web.config file under appsettings, but it's still generating the same error.
First I tried this, which didn't work
<add key="owin:AppStartup" value="false"></add>
Then I tried this, which also didn't work
<add key="owin:AppStartup" value="WebApplication1.App_Start.Startup" />
I'm relatively new to .net, can someone please advise what is the best course of action

Hi,
First do you really have a class named Startup in your project? If yes make sure about its full name (but AFAIK it should be found by default if really named "Startup").
See perhaps https://docs.microsoft.com/en-us/aspnet/aspnet/overview/owin-and-katana/owin-startup-class-detection for details.

You are most likely missing a reference to a dll that defines the attribute.
