实体框架 4.1 和通用 IRepository图案和温莎

我能够注入我的 DbContext 使用

    Component.For<IEFDataContextProvider>().ImplementedBy<EFDataContextProvider>().LifeStyle.PerWebRequest
        .DynamicParameters((k, d) => d["context"] = new PLSS.Models.PlssContext())

并且效果很好。但是，只有当我的上下文初始值设定项不需要删除数据库时，这才有效。

    DropCreateDatabaseAlways<PlssContext>

创建错误

无法删除数据库“PLSS.Models.PlssContext”，因为它当前正在使用中。

我认为这意味着这是从温莎容器中使用的。这与 PerWebRequest 的生活方式有关吗？我也尝试过 Transient 来解决同样的问题。

另外我将如何使用 xml 容器表示来创建组件。我宁愿把它放在我的 Windsor.config 中，这样我就可以在必要时更改它。

我认为这相当于我上面使用 Fluent api 所得到的结果，但我得到了一个奇怪的错误，我将在下面发布。

  <component
  id="IEFDataContextProvider"
  service="AGRC.Common.Repositories.IEFDataContextProvider, AGRC.Common"
  type="AGRC.Common.Repositories.EFDataContextProvider, AGRC.Common"
  lifestyle="PerWebRequest">
  <parameters>
    <context>
      ${PlssContext}
    </context>
  </parameters>
</component>

<component
  id="PlssContext"
  type="PLSS.Models.PlssContext, PLSS.Models"
  lifestyle="transient">
</component>

程序集“Microsoft.Web.Mvc，Version=2.0.0.0，Culture=neutral，PublicKeyToken=null”中类型“Microsoft.Web.Mvc.MvcDynamicSessionControllerFactory”中的方法“GetControllerSessionBehavior”没有实现。

不确定这是怎么回事，但是......

A follow up question to Entity Framework RC1 DbContext query issue

I am able to inject my DbContext using

    Component.For<IEFDataContextProvider>().ImplementedBy<EFDataContextProvider>().LifeStyle.PerWebRequest
        .DynamicParameters((k, d) => d["context"] = new PLSS.Models.PlssContext())

and this is working great. However this only works if my context initializer does not need to drop the database.

    DropCreateDatabaseAlways<PlssContext>

creates the error

Cannot drop database "PLSS.Models.PlssContext" because it is currently in use.

I assume that means that this is in use from the windsor container. Does this have to do with the LifeStyle being PerWebRequest? I have also tried Transient with the same issue.

Also how would I use the xml container representation to create the components. I'd rather have it in my windsor.config so I can change it if necessary.

I thought this would be equivalent to what I have above using the fluent api but i get a strange error i will post below.

  <component
  id="IEFDataContextProvider"
  service="AGRC.Common.Repositories.IEFDataContextProvider, AGRC.Common"
  type="AGRC.Common.Repositories.EFDataContextProvider, AGRC.Common"
  lifestyle="PerWebRequest">
  <parameters>
    <context>
      ${PlssContext}
    </context>
  </parameters>
</component>

<component
  id="PlssContext"
  type="PLSS.Models.PlssContext, PLSS.Models"
  lifestyle="transient">
</component>

Method 'GetControllerSessionBehavior' in type 'Microsoft.Web.Mvc.MvcDynamicSessionControllerFactory' from assembly 'Microsoft.Web.Mvc, Version=2.0.0.0, Culture=neutral, PublicKeyToken=null' does not have an implementation.

Not sure whats up with that but...
