azure-cosmosdb - Azure CosmosDB 表 API - table.CreateIfNotExists() 调用挂起

Question

我已经成功下载并运行了 Quickstart 应用程序，但我的 Web 应用程序无法正常工作。 (当我调用 table.CreateIfNotExists() 时，执行只是无限期挂起)。这显然与另一个图书馆发生冲突，但我无法确定确切的问题。

我已经尝试了我能想到的所有方法(包括删除和重新安装 WindowsAzure.Storage-PremiumTable 0.1.0-preview 库并安装)但无济于事。怀疑冲突与 Microsoft.AspNet.OData 库(用于 oData v4)有关，我在我的项目中也需要它。它对 Microsoft.Extensions.. (>= 1.0.0 && < 2.0.0) 有一些依赖性，我从另一个用户在线阅读是导致类似问题的原因，该问题已通过升级到 v2.0 解决。无论如何，由于 Microsoft.AspNet.OData 的依赖性，我无法升级这些。

以下是 成功 时的输出窗口(来自快速入门应用程序或其他具有最少附加库的应用程序):

Answer 1

转换为异步应该可以解决这个问题。

await table.CreateIfNotExistsAsync();
