配置 Enterprise Library 5.0 数据访问应用程序块

我试图弄清楚如何配置企业库 5.0 数据访问应用程序块。运行我的单元测试时，我收到以下错误：

Microsoft.Practices.ServiceLocation.ActivationException was caught
  Message=Activation error occured while trying to get instance of type Database, key "PokerAdviserProvider"
  InnerException: Microsoft.Practices.Unity.ResolutionFailedException
       Message=Resolution of the dependency failed, type = "Microsoft.Practices.EnterpriseLibrary.Data.Database", name = "PokerAdviserProvider".
Exception occurred while: while resolving.
Exception is: InvalidOperationException - The type Database cannot be constructed. You must configure the container to supply this value.

我得到这个的代码行：

var db = DatabaseFactory.CreateDatabase("PokerAdviserProvider");

App.config：

<configuration>
    <configSections>
        <section name="dataConfiguration" type="Microsoft.Practices.EnterpriseLibrary.Data.Configuration.DatabaseSettings, Microsoft.Practices.EnterpriseLibrary.Data, Version=5.0.414.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" requirePermission="false" />
    </configSections>
    <dataConfiguration defaultDatabase="PokerAdviserProvider" />
    <connectionStrings>
        <add name="PokerAdviserProvider" connectionString="server=(localhost);Initial Catalog=PokerAdviser;uid=abc;pwd=xyz"
            providerName="System.Data.SqlClient" />
    </connectionStrings>
</configuration>

我一直在谷歌上搜索了一下，找到了一些答案，这些设置也应该放在我的 app.Config 中unittest-project，但这没有什么区别。

我有点被困在这里，所以非常感谢任何帮助。

编辑：

我引用了正确的dll（来自Program Files的dll，而不是来自源代码的dll），所以这也不是问题。

I'm trying to figure out how to configure the enterprise library 5.0 Data Access Application Block.
When running my unittest, I get the following error:

Microsoft.Practices.ServiceLocation.ActivationException was caught
  Message=Activation error occured while trying to get instance of type Database, key "PokerAdviserProvider"
  InnerException: Microsoft.Practices.Unity.ResolutionFailedException
       Message=Resolution of the dependency failed, type = "Microsoft.Practices.EnterpriseLibrary.Data.Database", name = "PokerAdviserProvider".
Exception occurred while: while resolving.
Exception is: InvalidOperationException - The type Database cannot be constructed. You must configure the container to supply this value.

The line of code where I get this:

var db = DatabaseFactory.CreateDatabase("PokerAdviserProvider");

App.config:

<configuration>
    <configSections>
        <section name="dataConfiguration" type="Microsoft.Practices.EnterpriseLibrary.Data.Configuration.DatabaseSettings, Microsoft.Practices.EnterpriseLibrary.Data, Version=5.0.414.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" requirePermission="false" />
    </configSections>
    <dataConfiguration defaultDatabase="PokerAdviserProvider" />
    <connectionStrings>
        <add name="PokerAdviserProvider" connectionString="server=(localhost);Initial Catalog=PokerAdviser;uid=abc;pwd=xyz"
            providerName="System.Data.SqlClient" />
    </connectionStrings>
</configuration>

I've been googling around a bit and found some answers that these settings should also be put in the app.Config of my unittest-project, but that didn't make a difference.

I'm a bit stuck here, so any help is highly appreciated.

Edit:

I referenced the correct dll's (the ones from Program Files, not from the source code), so that isn't the problemneither.

我终于解决了这个问题：

Error: Activation error occured while trying to get instance of type Database, key "<database name>"

Inner Exception:  Resolution of the dependency failed, type = Microsoft.Practices.EnterpriseLibrary.Data.Database

我在 Windows 7、Enlib 5.0 上运行 VS 2010。以下内容对我有用。想要传播信息

确保您正确引用了 Microsoft.Practices.Unity.dll
获取最新的服务包VS 2010

I finally fixed this problem:

Error: Activation error occured while trying to get instance of type Database, key "<database name>"

Inner Exception:  Resolution of the dependency failed, type = Microsoft.Practices.EnterpriseLibrary.Data.Database

I was running VS 2010 on windows 7, Enlib 5.0. The following worked for me. Wanted to spread the word around
