问题 I have an old project developed with the Entity Framwork 4.0 which uses some complex types. Since I need to migrate it to .NET Core, I created a new project, installed all required libraries and used the command PM> Scaffold-DbContext "Server=ServerInstance; Database=DBName; Trusted_Connection=True;" Microsoft.EntityFrameworkCore.SqlServer -OutputDir Models on the existing database in order to create the new models. The problem is that it does not generate the complex type classes. I can

问题 Does EF 6 (code first) supports complex type collection(Value Object collections) mappings? I know that it supports Complex types, but haven't still found an example where we have a collection of complex types. For instance, suppose you have an entity called Student, which has a collection of contacts. With NH, I can simply say that Student has a collection of contacts and that contact is a component (equivalent to complex type in ef). Can this be done with EF without changing contact to an

问题 I an trying to create an XSD, to define complex types to be referenced in other XSDs. So far so good. Within this XSD (playlist.xsd) I have one main complexType "playlistType". I want the playlistType to be able to contain multiple instances of an element of type 'secondaryEventType', which I am trying to define as a separate complexType within the same XSD file. However, when I come to try to create the 'secondaryEvent' element within the 'playlistType' I am continuously getting the error

问题 In an XML schema can a complex type contain a choice of other complex types? I couldn't find any information about that. 回答1: Yes, see section 3.4.2 of the XML Schema reference; a complexType can indeed contain a choice element. Similarly, a choice element can contain one or more complexType elements (see section 3.8.2). 来源： https://stackoverflow.com/questions/11252175/choice-of-complex-types-in-an-xsd

问题 Question Is the following code wrong or is there an issue with the headers on Mac? The error does not appear on Linux, which leads me to conclude it is not incorrect code, although successful compilation on Linux is not a particularly rigorous test for ISO compliance. Source Code (MCVE) #include <stdio.h> #include <complex.h> void foo(const double *A, int *size){ for(int i=0;i < size[0]; ++i){ for(int j=0;j < size[1]; ++j){ printf("(%.2e,%.2e) ", creal(A[i + j * size[0]]), cimag(A[i + j *
