This pull request implements api v2. it's not fully tested but is functional:
#80

I'm using this temporary workaround:

public class ApiV1ToV2DelegatingHandler : DelegatingHandler
{
	protected override async Task<HttpResponseMessage> SendAsync(HttpRequestMessage request, CancellationToken cancellationToken)
	{
		var baseAddress = new Uri($"{request.RequestUri.Scheme}://{request.RequestUri.Host}:{request.RequestUri.Port}/api/v2/");

		var queries = HttpUtility.ParseQueryString(request.RequestUri.Query);

		var tenant = queries["tenant"];
		queries.Remove("tenant");

		var database = queries["database"];
		queries.Remove("database");

		if (string.IsNullOrWhiteSpace(tenant) || string.IsNullOrWhiteSpace(database))
		{
			var httpClient = new HttpClient
			{
				BaseAddress = baseAddress
			};

			var authIdentityResponse = await httpClient.GetFromJsonAsync<AuthIdentityResponse>("auth/identity", cancellationToken);

			tenant ??= authIdentityResponse?.Tenant;
			database ??= authIdentityResponse?.Databases.FirstOrDefault();
		}

		var uriBuilder = new UriBuilder(request.RequestUri)
		{
			Query = queries.ToString()
		};

		request.RequestUri = new Uri(uriBuilder.Uri.ToString().Replace(baseAddress.ToString(), $"{baseAddress}tenants/{tenant}/databases/{database}/"));

		var response = await base.SendAsync(request, cancellationToken);

		if (request.RequestUri.AbsolutePath.EndsWith("/query"))
		{
			var originalContent = await response.Content.ReadAsStringAsync(cancellationToken);

			var payload = JsonSerializer.Deserialize<Dictionary<string, object?>>(originalContent) ?? [];

			payload["data"] = null;

			var modifiedContent = JsonSerializer.Serialize(payload);

			response.Content = new StringContent(modifiedContent, Encoding.UTF8, "application/json");
		}

		return response;
	}
}

Here's an example of how it's used:

var handler = new ApiV1ToV2DelegatingHandler
{
	InnerHandler = new HttpClientHandler()
};

var httpClient = new HttpClient(handler);

var config = new ChromaConfigurationOptions("http://localhost:8000/api/v2/");

var client = new ChromaClient(config, httpClient);

AuthIdentityResponse can you share this class content only missing part

AuthIdentityResponse can you share this class content only missing part

public class AuthIdentityResponse
{
    [JsonPropertyName("user_id")]
    public required string UserId { get; set; }
    
    public required string Tenant { get; set; }
    
    public required string[] Databases { get; set; }
}
