Solution Explorer : Open Containing Folder stopped working

htconst commented 4 years ago

This is not a complaint, just something that I think you should know about. After the recent update of Mono a few days ago, the Open Containing Folder does not work anymore. I am using Linux Mint 19.3 with the Cinnamon desktop === Linux info ($ cat /etc/*-release)

DISTRIB_ID=LinuxMint DISTRIB_RELEASE=19.3 DISTRIB_CODENAME=tricia DISTRIB_DESCRIPTION="Linux Mint 19.3 Tricia" NAME="Linux Mint" VERSION="19.3 (Tricia)" ID=linuxmint ID_LIKE=ubuntu PRETTY_NAME="Linux Mint 19.3" VERSION_ID="19.3" HOME_URL="https://www.linuxmint.com/" SUPPORT_URL="https://forums.ubuntu.com/" BUG_REPORT_URL="http://linuxmint-troubleshooting-guide.readthedocs.io/en/latest/" PRIVACY_POLICY_URL="https://www.linuxmint.com/" VERSION_CODENAME=tricia UBUNTU_CODENAME=bionic

and the MonoDevelop info is the following: === MonoDevelop ===

I think I have found the cause: I suspect it has something to do with Shell Execute. I have a Gtk# 3 application that up until a few days ago would launch a browser thus: e.g. System.Diagnostics.Process.Start("http://www.github.com");

Today I discovered that the above code now throws an exception: System.ComponentModel.Win32Exception: Cannot find the specified file at System.Diagnostics.Process.StartWithShellExecuteEx (System.Diagnostics.ProcessStartInfo startInfo) etc...

So, I assume that something similar is happening with MonoDevelop not being able to Open the Containing Folder. As an aside, I modified my code to the following, and this works.

        using( Process proc = new Process() )
        {
            proc.StartInfo.UseShellExecute = true; 
            proc.StartInfo.CreateNoWindow = true;
            proc.StartInfo.FileName  = "firefox"; 
            proc.StartInfo.Arguments = "http://www.github.com";
            proc.Start();
        }

Hope this helps.

Mono version 6.12.0.122 fixes this issue: MonoDevelop's "Open Containing Folder" works again, and the System.Diagnostics.Process.Start("http://www.github.com"); works again as well.
