MAUI: Getting user secrets returns null

I did:

dotnet user-secrets init

then

dotnet user-secrets set "con" "123"

In my folder under:

/Users/juliustolksdorf/.microsoft/usersecrets/6b18f6d2-fda1-4673-b259-54176edbf6cc/secrets.json

I found a json secrets.json now containing my secret.

My csprof file now includes:

<UserSecretsId>6b18f6d2-fda1-4673-b259-54176edbf6cc</UserSecretsId>

And all I am trying in code is:

var con = Environment.GetEnvironmentVariable("con");

But null is returned.
Am I missing something? Seems like everything SHOULD be working...

There is no built-in support for this in .NET MAUI today, that's why it doesn't work unfortunately.

You can track the status in this issue: https://github.com/dotnet/maui/issues/4408

There is also a mention of a way of implementing this in your project if you want to use this today. The key code is pasted below, taken from here, full credit to Maksym:

    public static class Keys
    {
        public static string SyncfusionLicenseKey => Configuration?.Value<string>(nameof(SyncfusionLicenseKey)) ?? throw new NullReferenceException(nameof(SyncfusionLicenseKey));
        public static string MicrosoftAppCenterKey => Configuration?.Value<string>(nameof(MicrosoftAppCenterKey)) ?? throw new NullReferenceException(nameof(MicrosoftAppCenterKey));
        public static string CistApiKey => Configuration?.Value<string>(nameof(CistApiKey)) ?? throw new NullReferenceException(nameof(CistApiKey));

        private static JObject? Configuration { get; } = GetConfiguration("secrets.json");

        private static JObject? GetConfiguration(string filePath)
        {
            Assembly assembly = Assembly.GetExecutingAssembly();
            string? assemblyName = assembly.GetName().Name;
            using Stream? fileStream = assembly.GetManifestResourceStream($"{assemblyName}.{filePath}");
            if (fileStream == null)
            {
                return null;
            }

            using StreamReader sr = new(fileStream);
            string fileContent = sr.ReadToEnd();
            return JObject.Parse(fileContent);
        }
    }

Basically what this does is just load the json file as a manifest file and parse that.

You could maybe even make that code easier for .NET MAUI by using the file system helpers.
