I finally found the time to update the templates for IdentityServer4 to version 2. You can find the source code and instructions here.
To be honest, I didn’t have time to research more advanced features like post-actions (wanted to do automatic restore, but didn’t work for me) and VSIX for Visual Studio integration. If anyone has experience in this area, feel free to contact me on github.
Also – more advanced templates are coming soon (e.g. ASP.NET Identity, EF etc…)
