Description
Is your feature request related to a problem? Please describe.
I want to use this library to validate custom created / received AAD token as part of an Azure Function app.
To reuse code I would like to use the, currently internal, class AadIssuerValidator.
Describe the solution you'd like
Change class AadIssuerValidator from internal to public.
https://github.com/AzureAD/microsoft-identity-web/blob/master/src/Microsoft.Identity.Web/Resource/AadIssuerValidator.cs
Describe alternatives you've considered
I have to copy and paste the code out of this project and manually update it.
Additional context
I got an Azure Function app receiving AAD tokens. In the past I have copied this library into my project. Now that a NuGet feed is available I would like to switch and use it. This prevents me from doing it.
