执行Add-Migration Initial报错

执行Add-Migration Initial的时候，报错如下：

Your target project 'XX.XXX.Web' doesn't match your migrations assembly 'XX.XXX.DataBase'. Either change your target project or change your migrations assembly.
Change your migrations assembly by using DbContextOptionsBuilder. E.g. options.UseSqlServer(connection, b => b.MigrationsAssembly("XX.XXX.Web")). By default, the migrations assembly is the assembly containing the DbContext.
Change your target project to the migrations project by using the Package Manager Console's Default project drop-down list, or by executing "dotnet ef" from the directory containing the migrations project.

解决办法：

在Startup.cs文件里面

 public void ConfigureServices(IServiceCollection services)
        {
            services.AddControllers();
            //第一种方法
            //services.AddDbContext<TPLMSDbContext>(Options => Options.UseSqlServer(Configuration.GetConnectionString("TPLMSDbContext")));
            //第二种方法 services.AddDbContext<TPLMSDbContext>(options=>options.UseSqlServer("server=.\sqlexpress;database=XXX;uid=sa;pwd=*****", b => b.MigrationsAssembly("XX.XXX.Web")));
            services.AddMvc();                                 
        }

使用第二种方法

然后在执行：Add-Migration Initial
