Error CS1705: "which has a higher version than referenced assembly"

I've been looking into this for a bit now and haven't gotten it resolved. I get the following error message:

Compiler Error Message: CS1705: Assembly 'My.Model, Version=1.1.4422.23773, Culture=neutral, 
PublicKeyToken=bfde95ba233094b2' uses 
'Common, Version=3.3.4273.24368, Culture=neutral, PublicKeyToken=bfde95ba233094b2' 
which has a higher version than referenced assembly
'Common, Version=3.3.4269.17112, Culture=neutral, PublicKeyToken=bfde95ba233094b2'

c:\WINDOWS\assembly\GAC_MSIL\Common\3.3.4269.17112__bfde95ba233094b2\Common.dll: 
(Location of symbol related to previous error)

The web server is running Server 2003. I went to c:\windows\assembly and did in fact notice that there were 3 versions of Common.dll listed. The highest version listed was 3.3.4269.17112

I copied the dll with version: 3.3.4273.24368 into the assembly directory. I then re-compiled and re-deployed my code (probably overkill but oh well). When I opened my browser in a new session and went to the site URL again I still got the same message.

I can use windows explorer and verify the higher-versioned Common.dll is now listed as well.

What more can I look into to resolve this issue? I don't want to change the reference in my assembly to point to the older version.

Solution

  • 3 ideas for you to try:

    1. Make sure that all your dlls are compiled against the same version of Common.
    2. Check that you have project references in your solution instead of file references.
    3. Use binding redirections in your web.config. (Originally linked version at wayback machine)
