迁移如何将连接字符串传递到库项目 (.netStandard)

Migration How to pass Connection String into Library Project (.netStandard)

我的解决方案有 3 个项目:

我想将连接字符串从 WebAPI 传递到实体项目 我的启动 Class (WebAPI)

services.AddDbContext<ApplicationContext>(options => options.UseSqlServer(Configuration.GetConnectionString("DatabaseConnection")));

但是当我使用命令 Add-Migration InitialMigration 时出现错误:

No database provider has been configured for this DbContext. A provider can be configured by overriding the DbContext.OnConfiguring method or by using AddDbContext on the application service provider. If AddDbContext is used, then also ensure that your DbContext type accepts a DbContextOptions<TContext> object in its constructor and passes it to the base constructor for DbContext.

我解决了这个问题。因为在我的解决方案中有 2 个项目是 WebUI 和 WebAPI,我只是将包含连接字符串的 WebAPI 设置为启动项目并且它运行良好
