❔ How do I use a .cshtml (or Razor View) from a class library?

var pluginAssemblies =
    Directory.GetFiles(Path.Combine(AppContext.BaseDirectory), "plugin/*.dll", SearchOption.AllDirectories);

// Load DLL plugins.
foreach (var pluginAssembly in pluginAssemblies)
{
    try
    {
        var assemblyLoadContext = new AssemblyLoadContext(Path.GetFileName(pluginAssembly));
        var assembly = assemblyLoadContext.LoadFromAssemblyPath(pluginAssembly);
        var pluginTypes = assembly.GetTypes().Where(type => typeof(PluginBase).IsAssignableFrom(type));

        foreach (var pluginType in pluginTypes)
        {
            builder.Services.AddScoped(typeof(IPlugin), pluginType);
            builder.Services.AddControllersWithViews()
                .AddApplicationPart(pluginType.Assembly)
                .AddRazorRuntimeCompilation();
            
            builder.Services.Configure<MvcRazorRuntimeCompilationOptions>(o =>
            {
                o.FileProviders.Add(new EmbeddedFileProvider(pluginType.Assembly));
            });

            builder.Services.AddRazorPages().AddApplicationPart(pluginType.Assembly)
                .AddRazorRuntimeCompilation();
        }
    }
    catch (Exception ex)
    {
    }
}
