迁移 EF Core + ASP Identity + IdentityServer4 的问题

Question

尝试使用 Asp Core Identity 和 EF Core 实现 IdentityServer 4。 准确地说本教程（根据需要在它之前完成）：AspIdentity with EF Core

一切都很好，直到我必须运行迁移，这会引发错误：

An error occurred while calling method 'BuildWebHost' on class 'Program'. Continuing without the application service provider. Error: Invalid object name 'Clients'.
No DbContext named 'ConfigurationDbContext' was found.

                }
            }
        }
    }

注意：我在 ASP Core 2 框架中开始了全新的项目，因此不需要从 1.x 迁移到 2.0。

我做错了什么？

Answer 1

要运行实体框架迁移，您需要禁用 InitialiseDatabase 调用。

创建迁移后，您可以再次启用它。

Answer 2

我知道这不是您的答案，但如果其他人遇到此问题，我会找到另一个原因。在将 ConfigurationDbContext 添加到 IdentityServer 之前，我将其添加到 DI 容器中，这导致迁移无法通过 IdentityServer 添加。

启动：

var migrationsAssembly = typeof(Startup).GetTypeInfo().Assembly.GetName().Name;
var optionsContextBuilder = new Action<DbContextOptionsBuilder>(options => options.UseSqlServer(authConnectionString, sql => sql.MigrationsAssembly(migrationsAssembly)));
// This caused my migration to not get run
services.AddDbContext<ConfigurationDbContext>(options => options.UseSqlServer(authConnectionString));
services.AddSingleton(sp => new ConfigurationStoreOptions { ConfigureDbContext = optionsContextBuilder });
// The above two lines needed to be moved below these lines
identityServerBuilder
    .AddSigningCredential(certificate)
    .AddConfigurationStore(options => options.ConfigureDbContext = optionsContextBuilder)
    .AddOperationalStore(options => options.ConfigureDbContext = optionsContextBuilder)

希望这对其他人有帮助！
