C# Could not load file or assembly 'Microsoft.Practices.EnterpriseLibrary.Logging

Question

I am working with an ASP/C# web page. I am getting this error when submitting the page when I moved it to a server, but was not getting it when I was testing it on my local machine. I tried to look up a few things, but I was not getting a very clear answer in my opinion. Please let me know how to fix this..

WRN: Assembly binding logging is turned OFF.
To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1.
Note: There is some performance penalty associated with assembly bind failure logging.

Answer 1

source: Exception saying missing Microsoft.Practices.EnterpriseLibrary.Common.dll.

The problem is -

the enterprise library assembly reference propertiesare not marked "copy local"

[If you're using Visual Studio or something similar:] select the actual third party dll you are using, then go to properties and change the CopyLocal setting from False to True. This should resolve your issue.

You need to add the reference of binary. Copy the binary somewhere on your system from where EnterpriseLibrary installed and add it as reference.

You will need reference of your library. It is good that you place on dependency folder in your project when ever you are going to use any third party dll in your project. Try adding reference from that dependency folder, so when you ship your project in another machine you don't need to worry for installing and finding individual dll.
