Upgrading to Windows 10 breaks MySQL workbench?

问题:

I recently upgraded to the released version of Windows 10 using the automatic upgrade feature from Windows 8. In addition to some other stuff breaking, it seems that MySQL Workbench is now broken.

The program starts fine, but when you try to connect to a database, you are presented with a fatal error:

The type initializer for 'HtmlRenderer.Utils.FontsUtils' threw an exception.

This occurs even after a restart and seems to occur every time.

回答1:

The issue occurs due to the HTML rendered dll that is included in Workbench. Full details of the bug are here.

For a quick fix, thanks to Michael Gaillez and Frank Quintero, the offending code is in this repo: https://github.com/ArthurHub/HTML-Renderer

To fix it yourself, replace this code:

static FontsUtils()
    {
        _fontsMapping["monospace"] = "Courier New";
        _fontsMapping["Helvetica"] = "Arial";

        foreach (var family in FontFamily.Families)
        {
            _existingFontFamilies.Add(family.Name, family);
        }
    }

With this code:

static FontsUtils()
    {
        _fontsMapping["monospace"] = "Courier New";
        _fontsMapping["Helvetica"] = "Arial";

        foreach (var family in FontFamily.Families)
        {
            if (!_existingFontFamilies.ContainsKey(family.Name))
            {
                _existingFontFamilies.Add(family.Name, family);
            }
        }
    }
