创建新的控制器 - 错误运行所选代码生成器 [英] create new controller - error running selected code generator
问题描述
我正在使用Visual Studio Express 2013 for Web(特别是版本12.0.21005.1 REL)。这是我使用VS2013的第一个项目,我一直在使用VS2012直到这一点。
I am using Visual Studio Express 2013 for Web (specifically version 12.0.21005.1 REL). This is my first project using VS2013, I've been using VS2012 up until this point.
我正在尝试在我的asp.net MVC应用程序中创建一个新的控制器。我正在使用代码优先的实体框架5(.NET 4.5)。我想让Visual Studio为我创建一个模板(你知道一个控制器,具有读/写/删除等视图,而不是从头写自己的代码)。
I am attempting to create a new controller in my asp.net MVC application. I am using Entity Framework 5 with code first (.NET 4.5). I want Visual Studio to create the template for me (you know, a controller with views to read/write/delete etc, rather than write the code myself from scratch).
但是,每次尝试创建控制器时,都会收到以下错误消息:
However, every time I try to create the controller I get the following error message:
在VS中有某种错误2013?我不知道这是什么意思,重新启动VS2013没有帮助。
Is there some sort of bug in VS 2013? I can't figure out what this means, and restarting VS2013 does not help.
这里是血腥细节....实际上这是非常简单的,因为这是一个新的项目,迄今为止写的代码很少。
Here are the gory details.... actually it is all very simple since this is a new project with very little code written so far.
我的模型:
namespace ProfessionalSite.Models
{
public class EntityModels
{
public class Student
{
public int ID { get; set; }
public string LastName { get; set; }
public string FirstMidName { get; set; }
public virtual ICollection<Enrollment> Enrollments { get; set; }
}
public class Enrollment
{
public int ID { get; set; }
public string EnrollmentName { get; set; }
public string Credits { get; set; }
}
// Create the class that inherits from DbContext
// The name of this class is also used as the connection string in web.config
public class EFDbContext : DbContext
{
public DbSet<Student> Students { get; set; }
public DbSet<Enrollment> Enrollments { get; set; }
}
}
}
在我的网页。配置文件我有以下
And in my web.config file I have the following
<add name="EFDbContext"
connectionString="Data Source=JONSNA\SQLEXP2012WT;Initial Catalog=ProfessionalSiteDb; Integrated Security=True; MultipleActiveResultSets=True"
providerName="System.Data.SqlClient"/>
在标签内。
现在时间创建一个控制器。我右键单击解决方案资源管理器中的控制器,然后选择添加新的控制器。
Now time to create a controller. I right click on Controllers in the Solution Explorer, and choose to Add a new Controller.
然后
当我点击添加我得到
我不知道如何摆脱这个错误。我想作为一种解决方法,我可以自己键入代码,但我想知道这是一个错误或我做错了。在VS2012中,这只是工作...
I cant figure out how to get rid of this error. I guess as a workaround I can just type the code myself, but I'd like to know if this is a bug or something I have done wrong. In VS2012 this just worked...
我很感激任何帮助或指针。谢谢。
I'd appreciate any help or pointers. Thanks.
推荐答案
您不需要 EntityModels
以下:
namespace ProfessionalSite.Models
{
public class Student
{
public int ID { get; set; }
public string LastName { get; set; }
public string FirstMidName { get; set; }
public virtual ICollection<Enrollment> Enrollments { get; set; }
}
public class Enrollment
{
public int ID { get; set; }
public string EnrollmentName { get; set; }
public string Credits { get; set; }
}
// Create the class that inherits from DbContext
// The name of this class is also used as the connection string in web.config
public class EFDbContext : DbContext
{
public DbSet<Student> Students { get; set; }
public DbSet<Enrollment> Enrollments { get; set; }
}
}
然后当您创建控制器时,只需选择学生
或注册
为Model类。
Then when you create a controller, just select the Student
or Enrollment
for the Model class.
