Bug Report: Appwrite .NET SDK CreateOAuth2Token → project_provider_disabled

Issue

Using Appwrite .NET SDK (v3.1.0), CreateOAuth2Token for Google OAuth fails with:

412 Precondition Failed: project_provider_disabled

Even though Google OAuth is enabled in the Appwrite console, and the same project works fine using the Web/JS SDK.

Environment

• Appwrite .NET SDK: v3.1.0
• ASP.NET Core MVC (C#)
• Same Appwrite project as working Web/Next.js implementation

Failing Code

var authUrl = await _account.CreateOAuth2Token(
    OAuthProvider.Google,
    successUrl,
    failureUrl
);
return Redirect(authUrl);

also tried with

var authUrl = await _account.CreateOAuth2Token(
    Appwrite.Enum.OAuthProvider.Google,
    successUrl,
    failureUrl
);
return Redirect(authUrl);

Working Alternative

Manually constructing the OAuth URL works:

var authUrl =
    $"{endpoint}/account/sessions/oauth2/google" +
    $"?project={project}" +
    $"&success={Uri.EscapeDataString(successUrl)}" +
    $"&failure={Uri.EscapeDataString(failureUrl)}";

return Redirect(authUrl);

Root Cause

• .NET SDK performs a server-to-server HTTP request
• Web SDK only builds a redirect URL and lets the browser handle OAuth
• Server request loses browser context/cookies and can hit regional proxy inconsistencies
• Results in project_provider_disabled even when provider is enabled

Suggestion

• Align .NET SDK behavior with Web SDK (return redirect URL instead of server HTTP call)
• Improve consistency across regional endpoints for OAuth provider metadata
