Hi,
I have created vsix extension with wizard and project template and installed that extension. I have referenced below link and followed same steps to create that.
But while creating project with installed project template getting below error.
Error: this template attempted to load component assembly MyProjectWizard.dll, version=1.0.0.0, Culture= neutral, PublicKeyToken=899b6f2e68309a3a'. For more information on this problem and how to enable this template, please see documentation on Customizing Project Templates.
I have tried many options to solve this error but no success. Please tell how to fix this error.
Your help will be appreciated. Thanks in Advance

Shweta

Hi @ShwetaPaatil , I need to confirm something with you. Which version of Visual Studio are you using? What is your project template type? C# or VB project template? Have you installed the “Visual Studio extension development” workload in the Visual Studio Installer?
Hi,
I am using Visual Studio 2019 (Version 16.8.4)
Project template type is C#.
Yes I have already installed “Visual Studio extension development” component from the VS installer.
Regards
Shweta

I'm encountering the same issue VS2019 trying to set up a custom project template.
Any word on this?
Crikey I'm too tired for this.
Right, in my case I was missing a Zero on the version number. The version number must exactly match what is set in AssemblyInfo.cs
In this case I suspect it's because you've referenced the assembly as MyProjectWizard.dll where it should just be MyProjectWizard
For anybody else who stumbles into this mess.

If it helps anyone else, I also had this issue, but for a different reason.
When following this tutorial, I must have skipped step 3 in "Create a custom template wizard"
When looking at the vsix manifest, I noticed that my extension only had 2 items in it instead of 3. The first item was for the vsix project itself, the second is a reference to the project/item template, but a third item needs to be added.
The third item also points to the vsix extension, but to the Assembly rather than the project. Make sure you have a reference to a type "Microsoft.VisualStudio.Assembly" and pointing to your vsix project.
