Hi experts,
 
I am trying to build my package and build failed with following error:
I have checked on Build server, when performing DB sync on build machine I am getting the same error.
 
To fix this issue (On build server) I tried to stop service SQL reporting, stop iis , refresh model, full build (with custom models), and sync database but it not work. Message Error : Serialization version mismatch detect, make sure the runtime dlls are in sync with the deployed metadata. Version of file '209'. Version of dll '208'.
 
I found one blog where they suggested solution : Serialization version mismatch detect, make sure the runtime dlls are in sync with the deployed metadata. Version of file '209'. Version of dll '208.
But not sure how and where to check DLL as per above solution.
 
 
Build error:
Error during AOS update: Exception calling "CreateRuntimeProvider" with "1" argument(s): "Serialization version mismatch detect, make sure the runtime dlls are in sync with the deployed metadata. Version of file '209'. Version of dll '208'."

    Hi,
     
    Just deploy a new build box, it will also save you the hassle of clearing out the Dynamics Backup folders, and is good practice to do periodically anyway to ensure all the installed tools are up to date.

    If you really want to invest your time fixing the build server corrupted the attempted upgrade, the first step I recommend is deleting the modelstore backup. Inconsistency there with the actual F&O version can cause this error.

    Build error - Serialization version mismatch detect, Version of file 209. Version of dll 208
    Hi Martin,
     
    Before try to upgrade my build server on 10.0.40, I was successfully able to build the package but last
    week I tried to upgrade my build server on 10.0.40 but upgrade got failed and aborted my 10.0.40 build server upgrade.
    Still my build server is on 10.0.38 but after abort I am getting following build error.
     
    Please suggest the solution to fix following version error 
     "Serialization version mismatch detect, make sure the runtime dlls are in sync with the deployed metadata. Version of file '209'. Version of dll '208'."
     
    Note: I tried to do full build on my build server but still exist.

    You seem to be saying that you that you need 10.0.40 to build your code but your build server don't meet these requirements and therefore it can't build your code. The solution is creating a build server on the right version.

    If you have a problem with the upgrade, simply deploy a new VM on 10.0.40.

    Hi Martin
     
    Actually I was tried to upgrade my Build server from 10.0.38 to 10.0.40 but build was failed last week and
    I aborted my upgrade. Then I was trying to create build on earlier version 10.0.38 but build is failing with following error:
     
    "Serialization version mismatch detect, make sure the runtime dlls are in sync with the deployed metadata. Version of file '209'. Version of dll '208'."
     
    I can see still build version is on 10.0.38.

    It sounds like if you have a binary module in source control that's been built on a higher F&O version than what you have on your build server. Can't it be the case?
     
    When did it start failing? Did the build server worked but it started failed after a recent change? If so, what was the change?
