Azure Search .Net SDK使用SerializationBinder

Question

我正在使用.NET Core上的Azure Search .NET SDK（特别是从Github克隆样本 - https://github.com/Azure-Samples/search-dotnet-getting-started）

当使用索引（创建，删除...）输入任何操作时，它会抛出来自Newtonsoft.Json的SerializationBinder的异常

System.InvalidOperationException: Cannot get SerializationBinder because an ISerializationBinder was previously set.    at Newtonsoft.Json.JsonSerializer.get_Binder()

我相信SDK本身存在问题，因为我克隆了公共github repo。是吗？

Answer 1

这是由许多Azure SDK与JSON.NET版本10的已知兼容性问题引起的。详细信息为here和here。

这已在Microsoft.Azure.Search版本3.0.5和4.0.2预览中修复。

Answer 2

当我尝试执行 DeleteHotelsIndexIfExists 函数时，如果索引不存在，我也可以重复您提到的问题。 其他操作，例如创建索引，上传文档，我的工作正常。

经过一番调查，我发现 Microsoft.Extensions.Configuration.Json 是预览版。

请尝试更新至最新的稳定1.1.2版本。然后它在我身边正常工作。
