    When attempting to save a fiddler trace session file using FiddlerCap the 'Save Captures' dialog is unable to open and throws the following exception:

    See the end of this message for details on invoking 
    just-in-time (JIT) debugging instead of this dialog box.

    ************** JIT Debugging **************
    To enable just-in-time (JIT) debugging, the .config file for this
    application or computer (machine.config) must have the
    jitDebugging value set in the system.windows.forms section.
    The application must also be compiled with debugging
    enabled.

    For example:

    <configuration>
        <system.windows.forms jitDebugging="true" />
    </configuration>

    When JIT debugging is enabled, any unhandled exception
    will be sent to the JIT debugger registered on the computer
    rather than be handled by this dialog box.

    Hi Michael,

    It seems that most likely the Windows Forms' SaveFileDialog, which FiddlerCap is using, is missing from the Windows Server Core 2019 (1809) or there is a bug with it.
