That is the source code. But does not look like a standard plugin setup
Did you build it in Visual Studio to make a plugin ?
It needs a Plugin.json file to install

I took code from here

https://github.com/nopSolutions/nopCommerce-plugin-template-VS/tree/nopCommerce-4.20

Ok that is a temple for building a plugin.
So you combined the bits of both and made a PinPointSlider plugin.
Are you debuging it in Visual Studio ?

you are missing plugin.json.

Please add and try to build your project and then run.

I have updated git version still same error with plugin.json

Just uncomment below code in  PluginNopStartup.cs

   services.AddDbContext<PinPointSliderObjectContext>(optionsBuilder =>
            {
                optionsBuilder.UseSqlServerWithLazyLoading(services);
            });

below is working....

public class PluginNopStartup : INopStartup
    {
        public void ConfigureServices(IServiceCollection services, IConfiguration configuration)
        {
            services.AddDbContext<PinPointSliderObjectContext>(optionsBuilder =>
            {
                optionsBuilder.UseSqlServerWithLazyLoading(services);
            });

            services.Configure<RazorViewEngineOptions>(options =>
            {
                options.ViewLocationExpanders.Add(new ViewLocationExpander());
            });
        }

        public void Configure(IApplicationBuilder application)
        {
        }

        public int Order => 11;
    }

Yes, it works now, thank you :)
