Update to Non-Preview-Version of Microsoft.Identity.Web?

[Markus-Wolff]

Hi,
I want to use this sample app as base for another Teams-App, which uses Graph-API.
However, I have seen, that it still uses a preview-version of the package Microsoft Identity.Web, i.e. 0.1.3-preview.
It would be really helpful, if you can upgrade the sample app to this version or if you could provide some guidance for the upgrade. as there seem to be breaking changes. In the Microsoft.Identity.Web, I have not really found a clear guide, what needs to be changed, so that everything still works.
Thanks in advance.
