Upgrading 1.6 to 2.0RC

When I try and integrate a number of extensions, I get the following error:

The type or namespace name 'ExtensionSettings' could not be found

Any thoughts what could be causing this?

The Extensions in question are:

  • CommentRelish
  • SubscribeRemind
  • YouTubePlayer
  • VimeoPlayer

This is using the XML datasource

At the top of those .CS files (line #1), add:

using BlogEngine.Core.Web.Extensions;

Doh, knew it had to be something simple like this. Thanks Ben, always you are most helpful!

Hi Ben. Would also like to upgrade from to RC 2.0. I added the line 'Using BlogEngine.Core.Web.Extensions' as you suggested, but there is still a compiler error: "Unknown server tag 'Blog: blog Cumulus'in my widget (Tag Cumulus). What can be causing this error? Are you kind enough to look after the code on this link 'http://blog.knigge.dk/page/Cumulus-Widget-for-BlogengineNet.aspx'. Thanks for your help!

@pokni - in that widget code behind files (widget.ascx.cs and edit.ascx.cs) add:

using App_Code.Controls;

This is the other big one to look out for.

In BlogCumulus.cs (in App_Code/controls), it has "namespace Controls" at the top.  Change that to "namespace App_Code.Controls".

I think that's the only change needed.

It works! Many thanks for your help and Merry Christmas!

Hi @ben or @rtur!

My theme which works fine in 1.6 gives a Build Error in 2.0 RC with respect to a Page_Load in Postview.ascx.cs. What causes this error? Can you help?

Build Error:'BlogEngine.Core.Web.Controls.PostViewBase' does not contain a definition for 'Page_Load'


using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

public partial class themes_Knigge_Postview : BlogEngine.Core.Web.Controls.PostViewBase
    protected string ImageName;
    protected string CategoryImage;
    protected string FeaturedImage;
    protected void Page_Load(object sender, EventArgs e)
        string imageRoot = BlogEngine.Core.Utils.AbsoluteWebRoot.ToString() +
        string catImageName;
        if (Post.Categories.Count > 0)
            catImageName = Post.Categories[0].Title.Replace(".", "");
            catImageName = "Noavatar";
        ImageName = catImageName + ".jpg";
        CategoryImage = imageRoot + catImageName + ".jpg";
        FeaturedImage = imageRoot + catImageName + "Featured.jpg";

        base.Page_Load(sender, e);

Someone else had this error too.

You can just delete that line:   base.Page_Load(sender, e).
