VS Add-in with Custom Configuration Section RRS feed

  • Question

  • I've been banging my head on this one for 3 days now:


    I finally took the time to get a basic example working.


    Getting a Custom Configuration Section usable in a VSAddin:


    Instead of giving you all my code that isn't pertaining to the issue, I wrote up a simple sample.
    And instead of using my own, I found this:
        //How to: Create Custom Configuration Sections Using ConfigurationSection

    and used that code straight from msdn.


    This code (which works fine at the msdn url above) does not work:

    private static string hardCodedSectionGroupName = "pageAppearanceGroup";
    private static string hardCodedSectionName = "pageAppearance";

    public static PageAppearanceSection RetrievePageAppearanceSection()
               PageAppearanceSection config = (PageAppearanceSection)System.Configuration.ConfigurationManager.GetSection(hardCodedSectionGroupName + "/" + hardCodedSectionName);
        return config;




    When I put that msdn code into a VSAddin project, it would not read the configuration data.

    The crazy thing is that I can read basic AppSettings/(Key/Value pair) just fine.

    I cannot for the life of me figure out what the deal is with the custom ConfigurationSection (PageAppearanceSection in this case).

    I get the same error over and over.

    "An error occurred creating the configuration section handler for
    Could not load file or assembly 'Project1' or one of its dependencies.
    The system cannot find the file specified.

    So I wrote another method, just to test out the error above.
    private static void ShowThatTheAssemblyandTypesExists()
    And it knows about "Project1"(.dll) just fine and dandy.


    The conflicting issue is:
    ShowThatTheAssemblyandTypesExists() works just fine.
    I then catch 2 exceptions (with very unique names)
    catch (Exception are_You_Serious_QuestionMark_Ex1)
    catch (Exception are_You_Serious_QuestionMark_Ex2)

    which both exceptions say the same thing "I don't know anything about Project1(.dll)".



    One method knows all about Project1(.dll), and a few lines later, it says "I don't know anything about Project1(.dll).


    You may have to alter the location and path-reference (inside of the contents of the file) VSReadingBasicConfigAddin - For Testing.AddIn  (<<this file is in a zip that is inside the primary zip file.)

    The starting place to put a breakpoint would be:
    public static PageAppearanceSection RetrievePageAppearanceSection()

    If you want it to work (out of the box), then unzip to this directory:
    But you can unzip it anywhere of course......
    (and also put that "VSReadingBasicConfigAddin - For Testing.Addin" in the correct place)

    If you don't unzip it to the above location, you'll have to edit a path in the file:

    VSReadingBasicConfigAddin - For Testing.AddIn



    Go to the above URL, and you can download it.  Its a zip file.
    Note, I think there is a 90 day limit, so if you don't find it, its probably way too old.

  • Thanks for your sharing, this would help the people who met the same problem.

    Only one thing, when I try to take a look at it, the download URL is complaining "different ip". :(

  • I was able to download the code from home (where I had posted the code from work), and had a colleague (not at my work) download it as well.

    You might try an alternate browser.


    You can also try this "slightly more direct" URL:





    ALSO, I've also posted the source code in an alternate way.

    You can get a copy of the zip using the svn command line


    cd c:\
    mkdir tempVSAddinIssue
    cd tempVSAddinIssue

    svn.exe export http://granadacodersvn.svn.beanstalkapp.com/dotnet/misc/VSAddinReadingBasicConfig.zip VSAddinReadingBasicConfig.zip --username granadacodersvnReadOnly --no-auth-cache --force


    The password (when you are prompted) is:



    (If you don't have a SVN source-control client command line tool, you can get one at:




    (Please note that if you are reading this in the future (say anything past (Summer 2010)..... and the command line svn.exe call does not work, then assume I am no longer using beanstalk)

    At this point, if anyone could just retrieve the code, run it, and go "yeah, that's weird", that would be a big help......just a sanity check.

  • No 'love' on this one I guess.  I guess I'm confused, because having a non-hacky custom configuration section handler in a VSAddin would seem to me to be a pretty common need. 

    Ok, I'm off to hack-up a AppSetting(s) based version. :<

    If anyone has any input, please let me know and that would still be appreciated ... so I can go back and re-factor it correctly.
