Could not load file or assembly 'Microsoft.Owin' or one of its dependencies.
<p>I got the "Could not load file or assembly 'Microsoft.Owin' or one of its dependencies."</p>

<p>My scenario is, i have multiple asp.net mvc projects in my solution, when i pick any one of the project as startup it is working fine but at the same time the other project got this error. All the projects are hosted as different applications in IIS for this solution.</p>
