Important

The SECRETS.cs file is removed as private API keys are stored inside. To fix it, either:

• Remove the code that is causing the error, which will remove the ability to use Google Safe Browsing & sign in to Google.
• Generate a new C# class called "SECRETS":

namespace SLBr
{
    static class SECRETS
    {
        public const string GOOGLE_API_KEY = "";
        public const string GOOGLE_DEFAULT_CLIENT_ID = "";
        public const string GOOGLE_DEFAULT_CLIENT_SECRET = "";
        public const string YANDEX_API_KEY = "";
        public const string PHISHTANK_API_KEY = "";
        public const string WEATHER_API_KEY = "";
        public const string AMP_API_KEY = "";
        public const string GOOGLE_TRANSLATE_ENDPOINT = "";
        public const string MICROSOFT_TRANSLATE_ENDPOINT = "";
        public const string LINGVANEX_ENDPOINT = "";
        public const string YANDEX_LANGUAGE_DETECTION_ENDPOINT = "";
        public const string YANDEX_ENDPOINT = "";
        public const string LANGUAGETOOL_SPELLCHECK_ENDPOINT = "";
        public const string MICROSOFT_SPELLCHECK_ENDPOINT = "";
        public const string YANDEX_SPELLCHECK_ENDPOINT = "";
