c# - IdentityServer4 .net core 3.1 找不到名为“ConfigurationDbContext”的 DbContext

Question

我正在尝试使用IdentityServer4 (3.1.0)和.net core 3.1实现身份提供程序 当我尝试为 . 添加迁移时ConfigurationDbContext，它给了我以下错误：

No DbContext named 'ConfigurationDbContext' was found.

在我的 Startup.cs 中ConfigureServices，Configure方法如下：

public void ConfigureServices(IServiceCollection services)
        {
            var connectionString = Configuration["connectionStrings:UserDBConnectionString"];
            services.AddDbContext<UserContext>(o => o.UseSqlServer(connectionString));

            services.AddScoped<IGuayabaUserRepository, GuayabaUserRepository>();

            var identityServerDataDBConnectionString =
               Configuration["connectionStrings:identityServerDataDBConnectionString"];

            var migrationsAssembly = typeof(Startup)
                .GetTypeInfo().Assembly.GetName().Name;

            services.AddControllersWithViews();

            services.AddIdentityServer()
                .AddSigningCredential(LoadCertificateFromStore())
                .AddGuayabaUserStore()
                .AddConfigurationStore(options =>
                    options.ConfigureDbContext = builder =>
                    builder.UseSqlServer(identityServerDataDBConnectionString, sqlOptions => sqlOptions.MigrationsAssembly(migrationsAssembly)))
                .AddOperationalStore(options =>
                    options.ConfigureDbContext = builder =>
                    builder.UseSqlServer(identityServerDataDBConnectionString, sqlOptions => sqlOptions.MigrationsAssembly(migrationsAssembly)));
        }

        // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
        public void Configure(IApplicationBuilder app, IWebHostEnvironment env, ConfigurationDbContext configurationDbContext,
            PersistedGrantDbContext persistedGrantDbContext)
        {
            if (env.IsDevelopment())
            {
                app.UseDeveloperExceptionPage();
            }
            else
            {
                app.UseExceptionHandler("/Home/Error");
                // The default HSTS value is 30 days. You may want to change this for production scenarios, see https://aka.ms/aspnetcore-hsts.
                app.UseHsts();
            }

            configurationDbContext.Database.Migrate();
            configurationDbContext.EnsureSeedDataForContext();

            persistedGrantDbContext.Database.Migrate();

            app.UseIdentityServer();
            app.UseHttpsRedirection();
            app.UseStaticFiles();

            app.UseRouting();

            app.UseAuthorization();

            app.UseEndpoints(endpoints =>
            {
                endpoints.MapControllerRoute(
                    name: "default",
                    pattern: "{controller=Home}/{action=Index}/{id?}");
            });
        }

我安装了以下 nuget 包： IdentityServer4 (3.1.0)
IdentityServer4.AccessTokenValidation (3.0.1)
IdentityServer4.EntityFrameworkCore (3.1.0)
Microsoft.EntityFrameworkCore.SqlServer (3.1.0)
Microsoft.EntityFrameworkCore.Tools (3.1.0)

我尝试在包管理器控制台中执行此命令后发生描述的错误：
Add-migration IdentityServerInit -context ConfigurationDbContext

从昨天开始我一直在网上搜索，仍然没有答案。我已经在 stackoverflow 和 github 中阅读了许多具有相同问题的问题，但到目前为止还没有运气。我什至从头开始创建了整个项目，只是为了看看我是否在某个地方出错了（还没有）。该错误消息对我来说没有意义，因为我没有将任何东西注册为单例，至少在我的存储库中。

但是值得注意的是，如果我不评论 ConfigureServices 上的 services.AddIdentityServer 部分，我将无法为自己的上下文进行添加迁移。

你们对如何解决这个问题有什么想法吗？谢谢！
