Azure VisualSearch fails with Unauthorized despite valid key

I feel I must be missing something obvious here. I've been trying to follow the instructions at https://learn.microsoft.com/en-us/bing/search-apis/bing-visual-search/quickstarts/sdk/visual-search-client-library-csharp. I created a "Bing Search" service in Azure with the S9 tier which supports Visual Search. I went to the Keys and Endpoint section and copied the Key 1 out and put it in the below code, yet every time I run it I get Unauthorized:

{"code":"401","message": "Access denied due to invalid subscription key or wrong API endpoint. Make sure to provide a valid key for an active subscription and use a correct regional API endpoint for your resource."}

var client = new VisualSearchClient(new Microsoft.Azure.CognitiveServices.Search.VisualSearch.ApiKeyServiceClientCredentials("<key>"));

ImageInfo ImageInfo = new ImageInfo(url: "https://media.vanityfair.com/photos/5d9f5be40fa2040008f28470/4:3/w_1776,h_1332,c_limit/always-sunny-in-philadelphia-hangs-in-there.jpg");
VisualSearchRequest VisualSearchRequest = new VisualSearchRequest(imageInfo: ImageInfo);

var result = await client.Images.VisualSearchMethodAsync(knowledgeRequest: JsonConvert.SerializeObject(VisualSearchRequest));

The instructions don't say anything about setting an endpoint, but I tried that too, setting the Endpoint property from the one in my Keys and Endpoint page:

client.Endpoint = "https://api.bing.microsoft.com/";

But that just result in a NotFound error.

Anyone have any idea what's going on? I tried both keys with no success. Here's a LINQPad repro of the issue: http://share.linqpad.net/c3p8vo.linq

Thanks!

I figured out the issue. The documentation is actually wrong (as of 8/9/22). It says

The NuGet Visual Search package. From the Solution Explorer in Visual Studio, right-click on your project and select Manage NuGet Packages from the menu. Install the Microsoft.Azure.CognitiveServices.Search.VisualSearch package.

But that's the old nuget package, which has the old endpoint in it: https://api.cognitive.microsoft.com. The new endpoint is https://api.bing.microsoft.com. I found that there's actually another, newer nuget package, Microsoft.Bing.Search.VisualSearch which has the correct endpoint, but I can't find documentation anywhere pointing to it!

Once I switched to that nuget package though, everything worked as expected when passing an imageUrl. I still can't get it to work with a FileStream though, I think that might be broken as well.
