SYSLIB1045 Quick fix generates badly formed string

[vsfeedback]

This issue has been moved from a ticket on Developer Community.

Create the following class:

public static class Foo
{
    public static readonly Regex IllegalCharactersRegex = new("[" + @"\/:<>|" + "\"]", RegexOptions.Compiled);
}

The quick fix suggest to convert the regex to 'GeneratedRegexAttribute'.

If you do, it generates the following code :

public static partial class Foo
{
    public static readonly Regex IllegalCharactersRegex = MyRegex();

[GeneratedRegex(@"[\/:<>|"]", RegexOptions.Compiled)]
    private static partial Regex MyRegex();
}

But the string is badly formed. It should be @"[\/:<>|""]" instead.
