Asp.Net Core Mvc Plugins Manager

That is an open-source plugin(modular) and multi-tenant application framework built with ASP.NET Core, and a content management system (CMS) built on top of that application framework. Include a main project without referencing it using mvc structure in .dll projects as a plugin

Installation

.Net Core Mvc Plugins Manager is available on NuGet

dotnet add package Ege.AspNetCore.Mvc.PluginsManager

or

PM>Install-Package Ege.AspNetCore.Mvc.PluginsManager

Usage

Create Project as Sdk="Microsoft.NET.Sdk.Razor" or Sdk="Microsoft.NET.Sdk.Web" Choose build output path

Sample Plugin.Tax plugin project in Plugin.Tax.csproj :

<Project Sdk="Microsoft.NET.Sdk.Razor">
  <PropertyGroup>
    <TargetFramework>netcoreapp3.0</TargetFramework>
    <AddRazorSupportForMvc>true</AddRazorSupportForMvc>
  </PropertyGroup>
    ...
  <PropertyGroup Condition="'$(Configuration)|$(Platform)'=='Debug|AnyCPU'">
    <OutputPath>..\..\Applications\Application.WebMvc\Plugins\Plugin.Tax</OutputPath>
    <OutDir>$(OutputPath)</OutDir>
  </PropertyGroup>
</Project>

Add plugin info as json file PluginInfo.json :

{
  "Name": "Plugin.Widget",
  "File": "Plugin.Widget.dll",
  "Description": "Plugin Widget"
}

set File key as assembly name

Add Setup.cs like Asp.net core project for plugin:

using Ege.AspNetCore.Mvc.PluginsManager;
...
   internal class PluginSetup :IPluginSetup 
   {
       //for sorting between plugins middleware
       public int Order => 10;

       //your plugin ConfigureServices method
       public void ConfigureServices(IServiceCollection services)
       {
           //TODO:
       }
       //your plugin Configure method
       public void Configure(IApplicationBuilder app, IHostEnvironment env)
       {
           //TODO:
       }
   }
...

Add .Net Core MVC Main Project and some general Configurations for plugins

on Application.WebMvc.csproj include plugins dll in main project

<Project Sdk="Microsoft.NET.Sdk.Web">
...
  <ItemGroup>
    <Folder Include="Plugins\" />
    <Content Remove="Plugins\**\Properties\*.json" />
    <Content Include="Plugins\**\*.dll">
      <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
    </Content>
  </ItemGroup>
...
  <Target Name="CreatePluginFolder" AfterTargets="AfterPublish">
    <MakeDir Directories="$(PublishDir)Plugins" Condition="!Exists('$(PublishDir)Plugins')" />
  </Target>
...
</Project>

And configure Startup.cs to load plugins

using Ege.AspNetCore.Mvc.PluginsManager;
...

...
        public void ConfigureServices(IServiceCollection services)
        {
            services.AddControllersWithViews();
            ...
            //your plugin root directory
            var pluginRootPath = Path.Combine(AppContext.BaseDirectory, "Plugins");
            //load plugins
            services.AddPlugins(pluginRootPath);
            ...
        }

        public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
        {
            ...
            app.UsePluginsConfigure(env);
            ...
        }
...
