Question

我正在努力将当前的ASP.NET应用程序从2.0迁移到4.0，并尝试将企业库从4.0迁移到5.0

我在配置文件中进行了所有必要的更改。所有应用程序都在处理项目配对机器，但它不能在我的机器上运行。

我得到的错误的堆栈跟踪---

Answer 1

我能够解决这个问题。我发现我已经安装了导致问题的ESB 2.0版本。每当应用程序尝试记录IIS用于查看ESB配置文件而不是web.config文件的内容时。一旦我卸载了ESB应用程序，一切都开始工作了。

Answer 2

对我来说，我正在打开另一个具有enterpriseLibrary的配置文件，但是本地应用程序配置文件中缺少该文件。我将以下内容添加到本地配置中，并且我已经过了错误。

  <configSections>
       <section name="loggingConfiguration" type="Microsoft.Practices.EnterpriseLibrary.Logging.Configuration.LoggingSettings, Microsoft.Practices.EnterpriseLibrary.Logging, Version=5.0.414.0, Culture=neutral" requirePermission="true" />
 </configSections>
