Most likely your program is launching, but then ends without producing any output. If there had been a problem you would have seen an error message.

To facilitate a complete analysis, make a snapshot of your workspace and post the link to it here.

The same problem happened to me, how can we solve this.

I see you started a new question, now post a snapshot of your workspace there.

This is a perfect example of what I suspected in my first answer. So, if we look at your program code:

class Program
{
    static void Main()
    {
    }
}

This is an "empty" program, it doesn't take in any input, and it doesn't produce any output.

So when you launch it, it will finish (successfully) and then you will get another console prompt.

Its wierd, cause what i see in my workspace is this System.Console.Write("enter ur mins"); but this is not included in the snapshot, and i only have one file, I dont have Program.exe.

The "Program.exe" file is created when you compile ("mcs"). And when you add code in the workspace editor, be sure to save your changes (with Ctrl-S or the "save" menu choice) before you compile.

So do you see the output line when you compile and run it now?

No, I do not see the output line.

According to the snapshot, the program code was changed at 4:00 PM, but it was last compiled at 3:06. So the version you were running was compiled from a previous edit.

I just compiled it again ("mcs Program.cs") and then ran it ("mono Program .exe") and I did see the message.

make sure to save the file before you comple the code with mcs.

try renaming the file, "Program.cs" to whatever you want and go thru the motions again. for some reason this worked for me.

i ended up deleting all extra "cs" and "exe" files, closing workspaces, starting a new workspace and everything started working as it should in the video after this one. except the different error code numbers but the error description was the same.

I had the same issue at first. Then I think I found the solution in the comments:

1) Save the workspace code 2) Compile the workspace code 3) Run the workspace code via "mono Program.cs"

You got it, "edit, save, compile, run".   And then "repeat as necessary". :wink:
