Hi,

I've just upgraded a DNN site from 9.2 to 9.4 successfully.

The only issue is that a module I've developed isn't working.

I've tried recompiling with Visual Studio and I get 356 errors all with similar error messages to this:

"The type or namespace name 'Entities' does not exist in the namespace 'DotNetNuke' (are you missing an assembly reference?)"

I've checked that the dotnetnuke dll is still referenced and using the object browser I can see it has the Entities namespace.

Has anyone else encountered this issue?

I'm stuck for what to do at the moment.

Best Regards,

Steve

One thing I should add is the line of code where this fails:

using DotNetNuke.Entities.Portals;

The error message as mentioned is:
Error 22
Description: The type or namespace name 'Entities' does not exist in the namespace 'DotNetNuke' (are you missing an assembly reference?)
File: C:\inetpub\wwwroot\dnn9_4dev\Website\DesktopModules\FlexiContent\EF\BackgroundImages\Image.cs
Line: 1
Column: 18
Project: EF

 

There are 356 similar errors in total.

Hello,

I've managed to get my project to compile, thankfully.

I googled the error a few times and in general (not specifically for DNN) and the common thing mentioned was the targeted .Net framework version.

The minimum for DNN 9.4 (https://www.dnnsoftware.com/docs/developers/requirements.html) is 4.7.2 and my projects were set to 4.5.1.

Also, I was using visual studio 2013.

I installed VS 2015 (for now), with no changes I got even more errors including the ones already mentioned. I changed the targeted .Net framework version to 4.7.2 and the project recompiled successfully.

Though my app is still not working at least I can now debug it.

Best Regards,

Steve
