c# - Azure 搜索错误 "Inheritance security rules violated"

Question

我正在 .NET 4.6.2 和 MVC v5.2.3 上运行，并使用最新的 3.0.1 Azure 搜索库。我的问题是搜索索引客户端使用以下代码抛出错误。在其他 .NET 4.5 Web 应用程序上不会发生这种情况。

var SearchIndexClient = new SearchIndexClient(AZURE_SEARCH_SERVICE_NAME, AZURE_SEARCH_INDEX_NAME, new SearchCredentials(AZURE_SEARCH_API_KEY));

我找到了这篇文章: https://github.com/dotnet/corefx/issues/11100

这似乎是相关的，但修复的实现不起作用。我没有使用 .NET core，所以这是我的假设，为什么它不适合我。我已经为此工作了大约一周，但最新的 Azure 搜索包并未修复错误，因此在此寻求一些帮助。

错误的完整转储。

如果您将 System.Net.Http 升级到版本 > 4.3.0(例如最新版本是 4.3.3)，那么问题就会消失。
