D365插件本地单元测试遇强名称程序集加载错误求助

我想要本地测试Dynamics 365插件，我的解决方案包含多个依赖项目，主插件项目依赖CRM.CLIENTE.Plugin.Repository等项目。

单元测试代码 #

namespace CRM.CLIENTE.Plugin.Test
{
    [TestClass]
    public class UnitTest1
    {
        [TestMethod]
        [Description("Teste Template ")]
        [Owner("Alexandre")]
        public void TestMethod1()
        {

            Guid id = Guid.NewGuid();

            // init
            XrmFakedContext fakecontext = new XrmFakedContext();
            XrmFakedPluginExecutionContext pluginContext = fakecontext.GetDefaultPluginContext();
            XrmFakedTracingService iTracing = new XrmFakedTracingService();
            
            //Prepare
            Entity target = new Entity("Contact") { Id = id };
            target.Attributes.Add("telephone1","90381290381  8876");

            Entity postimage = new Entity("Contact") { Id = id };
            postimage.Attributes.Add("telephone1", "90381290381  88763232");

            ParameterCollection inputParameter = new ParameterCollection();
            inputParameter.Add("Target", target);

            EntityImageCollection postImages = new EntityImageCollection();
            postImages.Add("PostImage", postimage);

            pluginContext.InputParameters = inputParameter;
            pluginContext.PostEntityImages = postImages;

            fakecontext.Initialize(new List<Entity>() { postimage });

            //Execute
            fakecontext.ExecutePluginWith<PreOperationFormatPhoneCreateUpdate>(pluginContext);

            //Assert
            Entity teste = fakecontext.CreateQuery("Contact").FirstOrDefault();
            Assert.Equals("903812903818876", teste["telephone1"]);

            iTracing.Trace("Tested Trace in Account Create");
        }
    }
}

        protected override void ExecuteCrmPlugin(IPluginExecutionContext context, IOrganizationService service)
        {
            IContactRepository _contactRepository = new ContactRepository();
            _contactRepository.formatarTelefone(context);
        }
    }
}

插件基类代码 #

namespace CRM.CLIENTE.Plugin.Comum
{
    public abstract class BasePlugin : IPlugin
    {
        public  IPluginExecutionContext localContext { get; set; }
        public IOrganizationService OrganizationService { get; private set; }
        public  void Execute(IServiceProvider serviceProvider)
        {
            if (serviceProvider == null)
            {
                throw new InvalidPluginExecutionException("serviceProvider");
            }

            try
            {
                localContext = (IPluginExecutionContext)serviceProvider.GetService(typeof(IPluginExecutionContext));
                if (!localContext.InputParameters.ContainsKey("Target"))
                    throw new InvalidPluginExecutionException("No target found");

                IOrganizationService service = ((IOrganizationServiceFactory)serviceProvider.GetService(typeof(IOrganizationServiceFactory))).CreateOrganizationService(null);

                ExecuteCrmPlugin(localContext, service);
            }
            catch (InvalidPluginExecutionException e)
            {
                throw (e);
            }
        }
        protected virtual void ExecuteCrmPlugin(IPluginExecutionContext localcontext, IOrganizationService service)
        {
            // Implementar o código do Plugin no proprio Plugin 
        }
    }
}

Repository项目代码 #

using CRM.CLIENTE.Plugin.Domain.Domain;
using CRM.CLIENTE.Plugin.Factory.Factory;
using CRM.CLIENTE.Plugin.Repository.Comum;
using CRM.CLIENTE.Plugin.Repository.Repository.Interface;
using Microsoft.Xrm.Sdk;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Text.RegularExpressions;
using System.Threading.Tasks;

namespace CRM.CLIENTE.Plugin.Repository.Repository
{
    public class ContactRepository : IContactRepository
    {
        public Entity formatarTelefone(IPluginExecutionContext context)
        {
            Entity entity2 = context.InputParameters["Target"] as Entity;

            Contact contato = new ContactFactory().d365ToObject(entity2);

            contato.TelefoneComercial = Regex.Replace(contato.TelefoneComercial, @"[^\d]", "");

            return new ContactFactory().objectToD365(contato);
        }
    }
}

运行错误信息 #

System.IO.FileLoadException: 'Could not load file or assembly 'CRM.CLIENTE.Plugin.Repository, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. A strong-named assembly is required. (Exception from HRESULT: 0x80131044)'

问题原因 #

Dataverse插件部署要求程序集必须是强命名的，而你的测试项目引用的依赖项目（如CRM.CLIENTE.Plugin.Repository）未进行强命名签名，导致测试加载程序集失败。

解决步骤 #

1. 为所有依赖项目添加强命名密钥

   • 右键点击需要签名的项目（如CRM.CLIENTE.Plugin.Repository、CRM.CLIENTE.Plugin.Comum、CRM.CLIENTE.Plugin.Service等），选择「属性」
   • 切换到「签名」选项卡，勾选「为程序集签名」
   • 在「选择强名称密钥文件」下拉框中选择「新建」，输入密钥文件名，取消勾选「使用密码保护密钥文件」（测试环境可简化操作），点击确定
   • 保存项目设置，重新生成所有项目

2. 更新测试项目引用

   • 删除测试项目中对未签名程序集的引用
   • 重新添加对签名后生成的程序集的引用（路径一般在项目的bin/Debug或bin/Release目录下）

3. 修复测试与插件逻辑问题（避免后续断言失败）

   • 主插件中需将Repository返回的格式化实体写回上下文：

     protected override void ExecuteCrmPlugin(IPluginExecutionContext context, IOrganizationService service)
     {
         IContactRepository _contactRepository = new ContactRepository();
         Entity formattedContact = _contactRepository.formatarTelefone(context);
         // 将格式化后的实体更新回Target参数
         context.InputParameters["Target"] = formattedContact;
     }
     

   • 测试代码中使用Assert.AreEqual替换Assert.Equals（后者是Object方法，不会触发测试断言）：

     Assert.AreEqual("903812903818876", teste["telephone1"]);
     

4. 重新运行测试

   • 清理解决方案，重新生成所有项目后执行单元测试
