DNN ModuleID not being passed from the code behind to the ascx - angularjs

Question

Backstory: I use a DNN (DotNetNuke) content management system to host VB.NET/Angular1 modules.
I'm currently having an issue where a value in the code-behind is not accessible in the View.ascx of my module. This is causing a fatal runtime error.
The code behind where the value is being passed to a publicly defined variable
The View.ascx where the variable is being used

I noticed that they reference View.ascx(2) as if there are two physical versions of the file in the project or on the server, but this is not the case.
Any ideas on what may be going on here? Please let me know should the post require additional information.

I've resolved the issue by rebuilding my local development instance of DNN to a version higher than that of the production instance and rebuilt the module. I believe one of the DLLs we use in our environment, PetaPoco was causing an issue when the module was installed on a lower version of DNN. Previously my local copy of DNN was 9.1.0.367, it is now 9.1.1.129 whereas the production instance is at 9.1.1.113 .
It's not ideal that fixing it required a total reinstantiation of my development environment, but I believe a simple upgrade to an equal or greater version of the destination site would have fixed the issue as well.

My best guess, based on the updated screenshot, is that your full class name is incorrect in your View.ascx. It is expecting a codebehind class "Christoc.Modules.icod.View", but no namespace is defined in your partial class which means it will default to your default project namespace (which I am assuming is different).
I would try two things.
1) Ensure the namespace is defined in your View.ascx.cs
Namespace Christoc.Modules.icod
Partial Class View
...
End Class
End Namespace
2) Make sure you are building your module's assembly into the correct /bin folder of your DNN installation.
