hello, has any of you ever tried to make a muodular application with .NETCore2 MVC?

most of you will have certainly put the views as embedded resources

this is because File Providers do not behave as we would expect

context.Services.Configure<RazorViewEngineOptions>(options =>
{
    options.FileProviders.Insert(/*...*/);
});

usually if we do not use the Embedded type but we use the normal one (assemby)

the compiler will create 2 .dll files, the first package.dll and the second pakage.Views.dll

the problem arises exactly here, the default FileProvider or ApplicationPart for some reason can not handle the CompiledRazorAssemblyApplicationPart

clashing with this problem and doing some reverse ingeniering I discovered how does the non-modular aplication to load the Vews.dll

if (File.Exists(ViewAssembypath))
{
	services.AddMvc().ConfigureApplicationPartManager(apm =>
	{
		foreach (var b in new CompiledRazorAssemblyApplicationPartFactory().GetApplicationParts(AssemblyLoadContext.Default.LoadFromAssemblyPath(ViewAssembypath)))
			apm.ApplicationParts.Add(b);
	});
}
else
	throw new Exception("PluginsManager: no Plugin View Assembly found: " + ViewAssembypath);

if you are working on something like this, I leave the link of my library to correctly manage the modules for a modular mvc project

NETCore.Mvc.PluginsManager

it is really simple to use it and above all to customize all the work phase of the pacchatto, or if you turn take a cue from my solution ;)

a small example of how it works:

how to start

using AUR.NETCore.Mvc.PluginsManager;

Constructors

Base

PluginsManager PM = new PluginsManager<interfaces.IPluginBase>("absolutePath of plugin folder");
Example
const string PluginFolder = "Plugins";
static PluginsManager<interfaces.IPluginBase> _Plugins;
public static PluginsManager<interfaces.IPluginBase> Plugins { 
    get { 
        if (_Plugins == null) 
            _Plugins = new PluginsManager<interfaces.IPluginBase>(Path.Combine(AppContext.BaseDirectory, PluginFolder)); 
        return _Plugins; 
    }
}

Load

public void ConfigureServices(IServiceCollection services)
{
    //...
    services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_1);
    Plugins.Load(services); // last row
}

Configure

public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
   //....
    Plugins.Configure(app, env);    // before default route

    app.UseMvc(routes =>
    {
        routes.MapRoute(
            name: "default",
            template: "{controller=Home}/{action=Index}/{id?}");

    });
}

on github you find everything you need to use it to the fullest
