I have a MVC 4 Project (Company.Project.WebUI), a project for all my model classes (Company.Project.Data) and a project for the DAL (Company.Project.Services).
How can I manage this with Code First Migrations?
I'm getting the following error when I write the command Add-Migration Init:
`
System.Reflection.ReflectionTypeLoadException: Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information.

When I write the command Add-Migration -StartUpProjectName "Company.Project.Services" Init I'll get also an error
`

Could somebody tell me what's the best way to use EF Code First Migration with different dlls?
I don't know why, but EF wants your DAL project to be set as the start up project in Visual Studio. I just had the same error and this solved the problem.
On Solution Explorer: Right Click to your DAL project -> select "Set as StartUp Project".

There was a breaking change. Uninstall the old one and install the new one.
Old behavior:
dnu commands install SecretManager
New behavior:

although no such file exist in my project it is Asp.Net MVC4 project with EntityFramework
i dont understand from where the error comes
That strange file name that you are seeing is AppHarbor compiling your cshtml/vbhtml files when you deploy. Any errors in those files (bad Model property calls, even bad HTML) can cause the build to fail on those files and provide some pretty cryptic errors.
Try setting the MvcBuildViews property to true (Here is how to do that via Phil Haack) and see if you can use Visual Studio to help localize and correct the error.
I have followed below steps to create database using code first approach.
Create classes
Launch package manager
Enable-Migrations -ContextTypeName -MyDb
Made change in Model class
execute 'Update-Database -Verbose'
Change was reflected in the database table
Now I connect to the database and delete table. When I am executing 'Update-Database -Verbose' command, my expectation was it will create table again but its failing with below error message.
PM> Update-Database -Force
Specify the '-Verbose' flag to view the SQL statements being applied to the target database.

Can anyone help? How can I create table again using code first approach?

There's a system table in the database that holds all the run migrations, so rerunning Update-Database shouldn't do anything. Unless you've changed your model in your project causing an Automatic Migration, where you haven't explicitly created the migration and Entity Framework is trying to match the database to the models.
As Raphaël mentioned, it's code first. You shouldn't be modifying the tables directly if you want to manage it through code first. If you really want to do this, you need to remove the migration from the __MigrationHistory system table so Entity Framework doesn't think the migration has run. Or use the Update-Database -Target:[migration target here] to downgrade/revert a database through the commandlet.
I'm trying to have my ASP.NET MVC2 controllers built using StructureMap but ASP.NET doesn't seem to remember that I've called ControllerBuilder.Current.SetControllerFactory in my Global.asax file.
Specifically I get the error that my controller has no parameterless constructor. The stack trace reveals that my custom ControllerFactory was never actually executed.
Here is my call to the method that should tell ASP.NET which ControllerFactory to use:
Sub Application_Start()
RegisterRoutes(RouteTable.Routes)
ControllerBuilder.Current.SetControllerFactory(GetType(StructureMapControllerFactory))
BootStrapper.RegisterDependencies()
End Sub
And here's the exception that I receive.
[TargetInvocationException: Exception has been thrown by the target of an invocation.]
System.RuntimeTypeHandle.CreateInstance(RuntimeType type, Boolean publicOnly, Boolean noCheck, Boolean& canBeCached, RuntimeMethodHandle& ctor, Boolean& bNeedSecurityCheck) +0
System.RuntimeType.CreateInstanceSlow(Boolean publicOnly, Boolean fillCache) +86
System.RuntimeType.CreateInstanceImpl(Boolean publicOnly, Boolean skipVisibilityChecks, Boolean fillCache) +230
System.Activator.CreateInstance(Type type, Boolean nonPublic) +67
System.Web.Mvc.DefaultControllerFactory.GetControllerInstance(RequestContext requestContext, Type controllerType) +80
Why is ASP.NET forgetting which ControllerFactory to use?
How is your StructureMapControllerFactory defined? Does it have a default constructor?
If not, try using that second overload of the SetControllerFactory method:
// First create the controllerFactory instance...
ControllerBuilder.Current.SetControllerFactory(controllerFactory);
You have to set your controllerFactory before you RegisterRoutes...
