我使用最新的3.0.1 Azure搜索库在.NET 4.6.2和MVC v5.2.3上运行。我的问题是搜索索引客户端使用以下代码抛出错误。这不会发生在不同的.NET 4.5 Web应用程序上。
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，但修复程序的实现并不起作用。我没有使用.NET核心，所以这是我的假设，为什么它不属于我。我已经在这方面工作了大约一个星期，并且最新的Azure搜索软件包没有修复错误，在这里寻求帮助。
完全转储错误。

如果您将System.Net.Http升级为版本＆gt; 4.3.0（例如最新版本是4.3.3）然后问题就消失了。
