[英]The type was not mapped after trying to scaffolded controller in browser
我收到错误消息:
未映射类型“ GMS_Sandbox_MVC.Models.Organization”。 通过使用Ignore方法或NotMappedAttribute数据批注检查类型是否未明确排除。 验证类型是否定义为类,不是原始的,嵌套的或泛型的,并且没有从EntityObject继承。 源文件:C:\\ source temp \\ GMS_Sandbox_MVC \\ GMS_Sandbox_MVC \\ Models \\ OrganizationRepository.cs>>行:14
源错误:
Line 12: {
Line 13: // GMSSandboxMVCContext context = new GMSSandboxMVCContext();
Line 14: GMSSandboxMVCContext context = new GMSSandboxMVCContext();
Line 15:
Line 16: public IQueryable<Organization> All
有人有什么想法可能导致这种情况吗?
错误日志中显示:
