【问题描述】：

我从 .NET Core 1.1 升级到 .NET Core 2.0 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，并且最佳扩展方法重载“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：我添加了“使用 Microsoft.EntityFrameworkCore;”

【问题讨论】：

2.0.0 RC1 刚刚发布到针对 netstandard 2.0 的 nuget

标签： c# asp.net-mvc postgresql asp.net-2.0 identityserver4

【解决方案1】：

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

解决方案：

        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;
            });
