Appconfiguration: Conflicts IAsyncEnumerable class under .NET Core 3.0

[xin9le]

Summary

If we use IAsyncEnumerable<T> class under .NET Core 3.0, build error occures because of conflict. Japanese error message is below.

型 'IAsyncEnumerable' が 'System.Interactive.Async, Version=3.0.3000.0, Culture=neutral, PublicKeyToken=94bc3704cddfc263' と 'System.Runtime, Version=4.2.1.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' の両方に存在します。

This occurs because the App Configuration library uses Ix.NET v3.x. C# 8.0 now supports asynchronous streams (= IAsyncEnumerable<T>) as language level, so this conflict increases the potential for users that want to use Azure App Configuration to suffer.

Expect

We want you to resolve conflict to develop under latest environment (C# 8.0 + .NET Core 3.0 + Azure App Configuration). I think that changing the System.Interactive.Async package version to v4 will fix this issue.

Today, Ix.Async v4 has been GA :)

@xin9le @aL3891 We just released version 2.1.0-preview-010380001-1099 of the Nuget package Microsoft.Extensions.Configuration.AzureAppConfiguration that no longer depends on System.Interactive.Async.
