    I'm trying to use flexviewr but the error "'HtmlHelper<dynamic>' does not contain a definition for 'C1' and no accessible extension method 'C1' accepting a first argument of type 'HtmlHelper<dynamic>' could be found (are you missing a using directive or an assembly reference?)" is happening.
    What can I do?

    Hi Yago,

    It seems like the C1.Web.Mvc and C1.Web.Mvc.Viewer NuGet packages are not added to your application. Please try to install these packages and rebuild the application. If the issue still persists, could you provide us with a sample replicating the issue?

    You may also refer to the link below to get started with C1 MVC PdfViewer:
