尝试使用Asp Core Identity和EF Core实现IdentityServer 4。 本教程准确无误（根据需要在其之前完成）：AspIdentity with EF Core
一切都很棒，直到我必须运行迁移，这会引发错误：

我的Startup.cs课程：
vcap注意：我在ASP Core 2框架中启动了全新的项目，因此不需要从1.x迁移到2.0。
我做错了什么？
答案 0 :(得分：4)
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。
答案 1 :(得分：0)
我知道这不是你的答案，但如果有其他人碰到这个我找到了另一个原因。我将ConfigurationDbContext添加到DI容器中，然后将其添加到IdentityServer，导致迁移不会通过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)
希望这有助于其他人！
