IdentityServer4 升级到 .NET Core 2.0 的问题（AddConfigurationStore、AddOperationalStore）

Question

我从 .NET Core 1.1 升级到 .NET Core 2.0 并遇到了以下问题（我还升级了一些库以支持 .net core 2.0）

CS1929 'ConfigurationStoreOptions' 不包含 'UseNpgsql' 的定义，最佳扩展方法重载 'NpgsqlDbContextOptionsExtensions.UseNpgsql(DbContextOptionsBuilder, string, Action)' 需要 'DbContextOptionsBuilder'

类型的接收器

Startup.cs

        services.AddIdentityServer()
            .AddSigningCredential(Certificate.Get())
            .AddAspNetIdentity<User>()
            .AddConfigurationStore(builder =>
                builder.UseNpgsql(connectionString, options =>
                    options.MigrationsAssembly(migrationsAssembly)))
            .AddOperationalStore(builder =>
                builder.UseNpgsql(connectionString, options =>
                    options.MigrationsAssembly(migrationsAssembly)));

使用 UseSqlServer 时出现同样的问题

// configure identity server with in-memory users, but EF stores for clients and resources
services.AddIdentityServer()
    .AddTemporarySigningCredential()
    .AddTestUsers(Config.GetUsers())
    .AddConfigurationStore(builder =>
        builder.UseSqlServer(connectionString, options =>
            options.MigrationsAssembly(migrationsAssembly)))
    .AddOperationalStore(builder =>
        builder.UseSqlServer(connectionString, options =>
            options.MigrationsAssembly(migrationsAssembly)));

注意：我已经添加了"using Microsoft.EntityFrameworkCore;"

我自己也遇到了同样的问题。 IndentityServer4.EntityFramework github 的拖网显示了一个使用 ConfigureDBContext 属性

的示例 Startup.cs

解法：

        services.AddIdentityServer()
            .AddSigningCredential(Certificate.Get())
            .AddAspNetIdentity<User>()
            .AddConfigurationStore(options =>
            {
                options.ConfigureDbContext = builder =>
                    builder.UseNpgsql(connectionString,
                        sql => sql.MigrationsAssembly(migrationsAssembly));
            })
            // this adds the operational data from DB (codes, tokens, consents)
            .AddOperationalStore(options =>
            {
                options.ConfigureDbContext = builder =>
                    builder.UseNpgsql(connectionString,
                        sql => sql.MigrationsAssembly(migrationsAssembly));

                // this enables automatic token cleanup. this is optional.
                options.EnableTokenCleanup = true;
                options.TokenCleanupInterval = 30;
            });
