I was trying to create a plugin for the power platforms and data verse using .Net framework in visual studio code 2022 and created a new project with class library (.net) framework and then installed the required Nu get packages the Dynamics CRM and then added some more import statements and then when I navigate to the properties tab for the project the signing tab is not present in order to sign the assembly and create a key file and do some further steps in creating the plugin for power platform.
I am referring to this YouTube video for the creation of the plugin for the power platforms.
https://youtu.be/FwctAEGf07o?si=hLnH97XrwLtBaW_4
In this video the author starts with creating a new project with class file . Net framework with .Net version 4.6.2 and then do some changes to the default class file and then will go to properties pane of the project and will sign the assembly as in the below picture.

I am following this video as it is to create a power platform plugin, But facing the issue in signing the assembly and getting this error and signing tab is not present.

Can anyone help me to solve this???
