Exception trying to load Newtonsoft.Json Version 10 when calling CreateOrUpdateInstallationAsync

[Architekt909]

I'm using version 3.0.1 in my Azure Function project. Every time I call CreateOrUpdateInstallationAsync I get an exception saying that it's trying to load Newtonsoft.Json v10. I have Newtonsoft.Json version 11.0.2 installed (and require it, I can't use a lower version). I'm not sure why I'd be getting this, since the NotificationHubs package says it requires a version of the Json lib >=10.0.3. Here's the full exception details:

Edit1: I have no idea why it's bolding some chunks, tried editing it to remove it, couldn't figure it out
Edit 2: I tried downgrading package versions, and kept getting this exact same exception until I got down to version 1.0.9. This is the latest version I'm able to use without getting an exception.

I can 100% repro this using a very tiny function app. The only thing in this project is Newtonsoft.JSON 11.0.2, Microsoft.NET.Sdk.Functions 1.0.24, and Microsoft.Azure.NotificationHubs 3.0.1. Call the function (make sure to use a valid connection string and path, I removed mine for security reasons) and you'll trip the exception with the error I posted above.

I don't know if this is because I'm using Functions runtime v1 or not, but I can't upgrade to v2 due to Microsoft.SqlServer.Management.AlwaysEncrypted.AzureKeyVaultProvider not being compatible yet (an issue raised that's been in progress for a very long time at this point).

@Architekt909 thanks for reporting this. Azure Functions v1 does not support binding redirects, and so unfortunately .NET will not automatically load Newtonsoft.Json 11.0.2 instead of 10.0.3. You can read more about the issue in this bug: Azure/azure-functions-host#992

The assembly loading issue should be fixed in Azure Functions v2, but it sounds like you aren't able to use v2 yet.

At this time we don't have a solution for resolving the assembly loading issue with Newtonsoft.Json and Azure Functions v1.

Is there any problem with me using an older version? 1.0.9 works for me, and I seem to be getting push messages on both Android and iOS.
