How can I remove certain fields from the "Configure your new project" when creating a new project template in visual studio?
For an example, there is a Framework section where you can choose your Framework.
I within my project template already set the Framework in my .vstemplate file and ProjectTemplate.csproj.
I want to remove this field so the user won't need to select it.
Is there any API or a way to do so?

The solution is to remove the RequiredFrameworkVersion element, You can refer to the docs:
