Error in the start of WPF Application

Good afternoon:

I have an application in Microfocus Cobol - WPF that was working until a few hours ago. In the meantime, I've been updating some NuGet packages and, from that point on, when the application starts, it immediately gives an error that is as follows: "

System.ArgumentException

Message=

Can anyone help me with this situation?

  • I have never seen this exact error before but the error "An item with the same key has already been added" normally means that there is a duplicate property name, etc defined somewhere. If this was working fine and, you did not change anything in your WPF xaml or COBOL code, but you updated some NuGet packages then it is most likely one of those packages or added project references that is causing the error.

    Is it possible to undo the NuGet changes you made one at a time to see if and when it starts working again?

  • Hi Chris,

    I didn't change anything in the application, especially in the initial program that just calls up a screen with the user and password.
    I also tried to downgrade but in the meantime another problem appeared that I reported to Microfocus support and did not post on the forum.

    This problem prevents me from achieving an error-free compilation and so I cannot see if the initial error disappears.



    The new problem it's that: I can't program beyond column 72.

    I don't know what happened but now it's like this. The configuration of the source format is VARIABLE.

    I already have a response from support for this situation and they will do a Webex to check.
    
    When this problem is resolved and I am able to compile, I will test again to see if the initial error continues.

    Then I will give feedback.

    Best regards

  • It sounds like your project has become corrupt. You might try to place the sourceformat"variable" directive directly at the top of the source program in which you are seeing the error.

    $SET SOURCEFORMAT"VARIABLE"

  • What version of Visual Studio and Visual COBOL version are you using?

  • Hi Chris,

    All the sources I open are in the same conditions (part in column 72).
    I received support from Raquel Campuzano who was checking and is also studying the case of column 72.

    She suggested that I disable "Backgound Syntax Checking" and now the screen no longer appears
    broken and allows writing beyond column 72.

    It continues to give the compilation error with the information that the program is too large and therefore
    I am waiting for her response to what she asked me to do to move the process forward further.
    I am unable to test the situation that I reported with the initial error.

    Best regards
