C# VSIX-Templates: Trying to use a custom wizard results into an assembly reference error

Admin 1

I've been getting into C# item and project templates.

I followed Microsoft's documentation on how to make a custom Wizard, but whenever I try to use the item template that I have made, I run into an error.

https://docs.microsoft.com/en-us/visualstudio/extensibility/how-to-use-wizards-with-project-templates?view=vs-2019

The item template works, when I don't reference the WizardExtension tags in the vstemplate of the template, but that defeats my whole point of using tags and a wizard for pre-written code.

Could someone help me figure out why that is? I will include the files in case someone wants to try it for themselves or even help to correct them.

Thanks in advance!

Your wizard assembly is not strong-named. If you strong-name the assembly, and use the fullname of the assembly in your tag, I suspect that'll fix you up.

I wrote a blog entry that was subsequently archived detailing how to do this, which is now located at :

Creating a VSIX Deployable Project (or Item) Template with Custom Wizard Support

The first time you build the signed assembly, you'll need to retrieve it's PublicTokenKey, to fix up the tag in your .vstemplate. The following article shows how to add a custom tool to your Tools menu to easily retrieve that token string:

How to: Create a Tool to Get the Public Key of an Assembly

Also, you don't need that Package.cs file. But if you remove it, be sure you set the project's "Generate .pkgdef File" property to false, so you don't get a build error trying to generate a .pkgdef, and remove the corresponding Package asset from your .vsixmanifest.
