title: System.IO.FileLoadException
body: <p>I have got this error when using Enterprise Library 3.1 May 2007 version. We are developing a product and have a common lib directory beneath the Subversion Trunk directory</p>
  
  <p>&lt;>\Trunk\Lib\  into which we put all the third party DLLs. Inside this we have Microsoft\EnterpriseLibrary\v3.1 in which we have copied all the dlls from \Program Files\Microsoft Enterprise Library May2007\bin. Everything was working properly until one of the developers installed the source code on this machine. There were some dlls copied at the end of the source code installation and once that was done, he is not able to run the project anymore. He always gets this error</p>
  
  <p><strong>'Microsoft.Practices.EnterpriseLibrary.Data, Version=3.1.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)'</strong></p>
  
  <p>What is the problem here? I thought that when the source code was installed it was just supposed to build everything and copy in the bin directory within the source code parent directory. Also we have copied the Dlls from Microsoft Enterprise Library May 2007\bin directory into our product development directory and references into our project with a copylocal flag set to true. </p>
  
  <p>Can anyone help me out here</p>
  
  <p>RK</p>
