I just created new Web API project (using MVC) in visual studio 2015 and for the testing purpose, I ran that project but ended up below error.

After running the project, it brings up Home Page correctly but when I navigated to /api/values or /api/values/5, it gives me below xml message.

```
<Error>
    <Message>Authorization has been denied for this request.</Message>
</Error>

```

Can someone please help? I am new to Web API.
Please note that I don't want to remove the Authorize attribute. I would like to access the resource after authorization only. So I am looking for what is wrong.
