Unable to add app roles by editing the manifest file for the App Registered in https://apps.dev.microsoft.com/

Hi All,

Is it possible to implement Custom role based authentication for the app registered in https://apps.dev.microsoft.com with oauth2 endpoint similar to the article (https://azure.microsoft.com/en-in/resources/samples/active-directory-dotnet-webapp-roleclaims/) ? In this article the app was registered in portal.azure.com/ , where we can edit the manifest file to add the custom app roles. and the github sample uses oauth v1.0 endpoint to get access token and claims.

but the application which i'm building is registeredin https://apps.dev.microsoft.com/. i'm following this Azure sample (https://github.com/Azure-Samples/active-directory-dotnet-webapp-openidconnect-v2) to build my application, as of now i'm not able to add app roles by editing the manifest file. and i need to get the logged in users claim and role using oauth2 end point.

please suggest me any ideas. 

Thanks, Vivek
