Question

我正在尝试在我的Unity应用程序中实现Azure AD身份验证。我已经从这里的代码和文档开始：https://docs.microsoft.com/en-us/azure/active-directory/develop/quickstart-v2-windows-desktop。他们的Visual Studio示例项目工作正常，但是当我尝试在Unity项目中使用此代码时，尝试运行它时将失败。

string[] scopes = new string[] { "user.read" };     
public static string ClientId = {...} // my azure app id
private static string Tenant = {...} // my tenant id

private async void AsyncLoginButton()
    {
        AuthenticationResult authResult = null;

        string authority = "https://login.microsoftonline.com/" + Tenant;
        var app = new PublicClientApplication(ClientId, authority, TokenCacheHelper.GetUserCache());

        {...}

            try
            {
                authResult = await app.AcquireTokenAsync(scopes);                 
            }
            catch (MsalException msalex)
            {
                textContent.text = $"Error Acquiring Token:{msalex}";
                Debug.Log(msalex);
            }         

        {...}
    }

，出现以下错误-“无法注册窗口类，win32错误0”：

在上面的窗口中按OK后，它仅在AcquireTokenAsync的行中提供空引用。

我认为这是在代码尝试弹出要求您提供凭据的Microsoft Graph API窗口时发生的，但是由于某些原因，这在Unity中不起作用。

有什么想法吗？

谢谢。
