我正在尝试使用Enterprise Library 5.0的Logging Application块将简单消息记录到Win XP SP3系统上的Windows事件日志中,使用:

Logger.Write(msg);

尝试记录时,我收到"尝试获取LogWriter类型的实例时出现激活错误"错误消息.

下面显示的是MS Enterprise库使用的配置文件

我正在尝试使用Enterprise Library 5.0并在我的BL上进行一些单元测试,我是否需要在DL或Test项目上安装app.config？

注意:我的web项目上的web.config上已经有配置设置.

我如何使用DAAB:

private static Database db = DatabaseFactory.CreateDatabase();

db.ExecuteNonQuery("spInsertSalesman", salesman.Fullname);

我在DL上的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="DBTEST" />
    <connectionStrings>
        <add name="DBTEST" connectionString="Data Source=[dbsource];Initial Catalog=[dbname];User Id=sa;Password=password;"
            providerName="System.Data.SqlClient" />
    </connectionStrings>
</configuration>
