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ConfigurationDbContext添加迁移时，它给了我以下错误：

No DbContext named 'ConfigurationDbContext' was found.
在我的Startup.cs中，ConfigureServices和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软件包：
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）
当我尝试在包管理器控制台中执行以下命令后，发生了所描述的错误：
Add-migration IdentityServerInit -context ConfigurationDbContext
从昨天开始，我一直在网上搜索，但仍然没有答案。我已经在stackoverflow和github中阅读了许多与同一问题有关的问题，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，只是看我是否在某个地方出错了，什么也没有（至今）。该错误消息对我而言毫无意义，因为我没有将任何内容注册为单例，至少不是我的所有存储库。
但是，值得注意的是，如果不对ConfigureServices上的services.AddIdentityServer部分进行注释，则无法为自己的上下文进行添加迁移。
你们会对如何解决这个问题有任何想法吗？ 谢谢！
