在nhibernate的夏季放映中出现了令人讨厌的错误

我本想关注nhibernate screnncast系列的夏天，但我被困在了早期阶段。这就是问题所在：

当我尝试运行以下方法时：

public void GetMyTestDataXMLFile()
{
    SaveTestDatabase();
}

我得到以下错误：

    Test Report: file:///C:/Users/pina/AppData/Local/Temp/Gallio/TDNetRunner/Report/DataAccessLayerTest.dll.html

唯一的区别是我使用的是本地数据库（.sdf文件）。我确信它一定与连接字符串有关，但我似乎无法解决这个问题。

这是我的app.config文件：

    <?xml version="1.0"?>
<configuration>
    <configSections>
    </configSections>
    <connectionStrings>
        <add name="testDatabase"
             connectionString="Data Source=H:'Code'NHibernateSample'DataAccessLayer'FirstSample.sdf"
             providerName="Microsoft.SqlServerCe.Client.3.5"/>
    </connectionStrings>
</configuration>

我正在使用VS 2010。

有人能帮忙吗？

在nhibernate的夏季放映中出现了令人讨厌的错误

我已经设法弄清楚了。测试驱动框架似乎并不完全支持使用.sdf文件&SQLServerCe。我安装了一个新的SQL Server本地实例，并创建了一个全新的数据库，一切都得到了修复。

稍后我将发布新的app.config文件。
