New Post: ~remoteAppUrl Visual Studio Token for Provider-hosted app

Thanks for more clarification on your scenario. Unfortunately, there is nothing this CodePlex project can help. You may want to ask your customers to manually retract the .app package (as it's simply like a zip package) and update the manifest file.

From your description, it seems that you are building a provider-hosted app for your customers. In addtion to the ~remoteAppUrl, your customers also need to inject the Client ID into the manifest to make it work.

Thanks,
Xiaoying
