    Using Official Mailjet API v3 .NET Wrapper from Surface controller.

    I have been trying to integrate newsletter capabilities for a customer's web site, using Mailjet API.

    Official Mailjet API v3 .NET Wrapper uses asynchronous functions in order to contact the service. I have a SurfaceController, that gets an Id and tries to retrieve a contact from the Mailjet service.

    In order to use the retrieve method I used something like this:

        public class PageNewsletterFormController : RenderMvcController
    {
        public override ActionResult Index(RenderModel model)
        {
            string ContactID = Request.QueryString["id"];
            ContactModel contact = new ContactModel(model.Content);
    
            string ContactID = Request.QueryString["id"];
            ContactModel contact = new ContactModel(model.Content);
    
            JArray result = null;
    
            MailjetClient client = new MailjetClient(WebConfigurationManager.AppSettings["apiKey"], 
                WebConfigurationManager.AppSettings["apiSecret"]) { Version = ApiVersion.V3_1 };
    
            MailjetRequest request = new MailjetRequest
            {
                Resource = Contact.Resource
            }
            .Filter(Contact.ContactsList, WebConfigurationManager.AppSettings["contactslist"])
            .Filter(Contact.ID, ContactID)
            .Filter(Contact.Limit, "50");
    
            MailjetResponse response = client.GetAsync(request).Result;
    
            return CurrentTemplate(contact);
        }
    

    As soon as the code hits the GetAsync() method the page freezes.

    I tried to do the same with something like this:

        public class PageNewsletterFormController : RenderMvcController
    {
        public async Task<ActionResult> NewsletterForm(RenderModel model)
        {
            string ContactID = Request.QueryString["id"];
            ContactModel contact = new ContactModel(model.Content);
    
            JArray result = null;
    
            MailjetClient client = new MailjetClient(WebConfigurationManager.AppSettings["apiKey"], 
                WebConfigurationManager.AppSettings["apiSecret"]) { Version = ApiVersion.V3_1 };
    
            MailjetRequest request = new MailjetRequest
            {
                Resource = Contact.Resource
            }
            .Filter(Contact.ContactsList, WebConfigurationManager.AppSettings["contactslist"])
            .Filter(Contact.ID, ContactID)
            .Filter(Contact.Limit, "50");
    
            MailjetResponse response = client.GetAsync(request).Result;
    
            return CurrentTemplate(contact);
        }
    

    It has the same problem - it freezes.

    Is there someone that can offer any pointers?

    Thanks, George J.

    Bump - Having the same problem here (in fact, we're both working on the same project and we're stuck on this). Any advice?

    Hi,

    You may have already tried some these...

    I guess you're encountering a deadlock issue here. Looking at the above sample code I can't find an await keyword within an async method.

    Try using the await keyword e.g MailjetResponse response = await client.GetAsync(request);

    (Not the best solution) If within a non async method like i would expect in a SurfaceController (ChildActionOnly) then try calling using this MailjetResponse response = Task.Run(async => await client.GetAsync(request)).GetAwaiter().GetResult();

    Hope it helps. Cheers
