 ## About The Code
 
-The manual JWT validation occurs in the [TokenValidationHandler](https://github.com/Azure-Samples/active-directory-dotnet-webapi-manual-jwt-validation/blob/master/TodoListService-ManualJwt/Global.asax.cs#L58) implementation in the `Global.aspx.cs` file in the TodoListService-ManualJwt project. Each time a call is done on a controller method holiding the `[Authorize]` attribute, the TokenValidationHandler.SendAsync method is called:

 This method:
 
 1. gets the token from the Authorization headers
 2. verifies that the token has not expired
 3. gets the open id configuration from the Azure AD discovery endpoint
 4. Sets the parameters to validate:
-
-  - the audience - the application accepts both its App Id URI and its AppID/clientID
-  - the valid issuers - the application accepts both Azure AD V1 and Azure AD V2
-
+- the audience - the application accepts both its App Id URI and its AppID/clientID
+- the valid issuers - the application accepts both Azure AD V1 and Azure AD V2
 5. Then it delegates to the `JwtSecurityTokenHandler` class (provided by the `System.IdentityModel.Tokens` library)
 
-the `TokenValidationHandler` class is registered with ASP.NET in the `TodoListService-ManualJwt/Global.asx.cs` file, in the `application_start()` method :
