Resolve web links

[xperiandri]

Getting dependencies from the Web myself looks like implementing it one more time.
Is there a better way?

var fileProvider = environment.ContentRootFileProvider;
var httpClient = new Lazy<HttpClient>();
var options = new WebOptimazerScssOptions
{
    TryImport = (ref string file, string parentPath, out string scss, out string map) =>
    {
        map = String.Empty;

        var uri = new Uri(file, UriKind.RelativeOrAbsolute);
        if (uri.IsAbsoluteUri
        && (uri.Scheme.Equals("http", StringComparison.OrdinalIgnoreCase)
            || uri.Scheme.Equals("https", StringComparison.OrdinalIgnoreCase)))
        {
            scss = httpClient.Value.GetStringAsync(uri).Result;
            return true;
        }

        var fileName = Path.GetFileName(file);
        var path = Path.GetDirectoryName(file);
        var filePath = $"{path}/_{fileName}.scss";
        var fileInfo = fileProvider.GetFileInfo($"Areas/SecretCircle.BmwTheme/wwwroot/styles/{filePath}");
        if (fileInfo is Microsoft.Extensions.FileProviders.NotFoundFileInfo)
        {
            scss = String.Empty;
            return false;
        }
        else
        {
            using var reader = new StreamReader(fileInfo.CreateReadStream());
            scss = reader.ReadToEnd();
            return true;
        }
    }
};
