ASP.​NET Core on .NET 7.0 - File upload and streams using Minimal API

Given these endpoints you've written, do you know the proper way to call them using HttpClient? I've tried lots of variations, but I keep getting issues such as status code 415, header problems, streams that errantly include the multipart boundary instead of just the file, etc.

@ronwarner this is the IFormFileCollection upload code:

    private async Task UploadAsync(string url)
    {
        using HttpClient httpClient = new();
        MultipartFormDataContent content = new();

        using var stream1 = new MemoryStream("Content1"u8.ToArray());
        var fileContent1 = new StreamContent(stream1);
        fileContent1.Headers.ContentType = MediaTypeHeaderValue.Parse("application/octet-stream");
        content.Add(fileContent1, "files", "File1.txt");

        using var stream2 = new MemoryStream("Content2"u8.ToArray());
        var fileContent2 = new StreamContent(stream2);
        fileContent1.Headers.ContentType = MediaTypeHeaderValue.Parse("application/octet-stream");
        content.Add(fileContent2, "files", "File2.txt");

        var response = await httpClient.PostAsync(url, content);
        response.EnsureSuccessStatusCode();

        string responseContent = await response.Content.ReadAsStringAsync();

        Console.WriteLine(responseContent);
    }
