NuGet 更新，现在抛出 OpenTok：System.IO.FileLoadException：无法在 CreateSession 上加载文件或程序集 JWT Version=2.0.0.0

Question

我刚刚更新了所有 NuGet 程序包，但我无法再连接到会话。我是运行 OpenTok 3.1.0 和 JWT 6.1.0 但在 OpenTok.ConnectSession 上出现以下错误：

OpenTok = new OpenTok(apiKey, apiSecret);
SessionHost = OpenTok.CreateSession(mediaMode: MediaMode.ROUTED);   <-- error here

3/1/2020 7:40:08 AM ERROR:

看来我可能遇到了 JWT 版本控制问题，因为它在错误消息中引用了 2.0.0.0，而我已经安装了 6.1.0 并且在 packages.config 中。但是，我不知道为什么它会显示 2.0.0.0 或如何解决它。

Answer 1

jdweng 的评论直接导致了答案。 OpenTok 不适用于 6.1.0，卸载解决了这个问题。此后发布了 TokBox 问题，以找出它不起作用的原因。

NuGet 更新，现在抛出 OpenTok：System.IO.FileLoadException：无法在 CreateSession 上加载文件或程序集 JWT Version=2.0.0.0

NuGet update, now throwing OpenTok: System.IO.FileLoadException: Could not load file or assembly JWT Version=2.0.0.0 on CreateSession
