I am running on .NET 4.6.2 and MVC v5.2.3 with the latest 3.0.1 Azure Search library. My problem is that the search index client is throwing an error with the following code. This does not occur on a different .NET 4.5 web app.
var SearchIndexClient = new SearchIndexClient(AZURE_SEARCH_SERVICE_NAME, AZURE_SEARCH_INDEX_NAME, new SearchCredentials(AZURE_SEARCH_API_KEY));
I found this article: https://github.com/dotnet/corefx/issues/11100
Which seems to be related, but the implementation of the fix doesn't work. I am not using .NET core, so that is my assumption as to why it doesn't pertain to me. I've been working on this for about a week now and with the latest Azure Search packages not fixing the errors, looking for some help here.
Full dump of the error.
