使用Oracle.DataAccess.Client将EntLib 4.1升级到5

Question

我正在将项目从EntLib 4.1升级到EntLib 5.我已经浏览了迁移指南,更改了所有引用并更新了所有配置文件以指向EntLib 5.一切正常,接受Oracle数据库访问.使用配置文件:

<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="true" />
  </configSections>
  <dataConfiguration defaultDatabase="prod">
    <providerMappings>
      <add databaseType="Microsoft.Practices.EnterpriseLibrary.Data.Oracle.OracleDatabase, Microsoft.Practices.EnterpriseLibrary.Data"
        name="Oracle.DataAccess.Client" />
    </providerMappings>
  </dataConfiguration>
  <connectionStrings>
    <add name="prod" connectionString="Data Source=dev;User Id=dev;Password=dev;"
      providerName="Oracle.DataAccess.Client" />
  </connectionStrings>
</configuration>

与4.1一起工作的所有调用都DatabaseFactory.CreateDatabase()失败了:

System.InvalidOperationException: The type Database cannot be constructed. You must configure the container to supply this value.

如果我Oracle.DataAccess.Client用微软取而代之,System.Data.Oracleclient那一切都会再次起作用,但并不是ODP.net的可爱.有谁知道如何使用EntLib 5？

干杯,Mlk

它会导致Oracle安装程序有时会忘记安装在其中的数据库提供程序工厂machine.config.要解决此问题,需要将以下内容放入app.config或中machine.condig.

<system.data>
<DbProviderFactories>
<add name="Oracle Data Provider for .NET" invariant="Oracle.DataAccess.Client"
description="Oracle Data Provider for .NET" type="Oracle.DataAccess.Client.OracleClientFactory, Oracle.DataAccess, Version=2.102.2.20, Culture=neutral, PublicKeyToken=89b483f429c47342" />
</DbProviderFactories>
</system.data>

我认为在EntLib4中工作的是EntLib4使用以前版本的Oracle客户端(我认为是10.2.0.1.Oracle编号很奇怪).
