.NET C#: Running command line in CMD and waiting for it to finish

I had a script that i should call with command line interface, then other tasks that should be done after that.
I used the Process and ProcessStartInfo as below, but the problem i had is that the script was taking some time, and the program execution was failing after that since the script is not finished yet.

            using (Process process = new Process())
            {
                var startInfo = new ProcessStartInfo("cmd")
                {
                    RedirectStandardInput = true,
                    RedirectStandardOutput = true,
                    WindowStyle = ProcessWindowStyle.Normal,
                    UseShellExecute = false,
                    CreateNoWindow = false
                };

                process.StartInfo = startInfo;
                process.OutputDataReceived += (sender, e) => Console.WriteLine(e.Data);
                process.Start();
                process.StandardInput.Write("script"+ process.StandardInput.NewLine);
                process.Close();
            }

I wanted to make sure that the program execution waits till the script finishes.So instead of using Close method, i added WaitForExit, and i am manually sending exit command to the command line after the script finishes, like below

            using (Process process = new Process())
            {
                var startInfo = new ProcessStartInfo("cmd")
                {
                    RedirectStandardInput = true,
                    RedirectStandardOutput = true,
                    WindowStyle = ProcessWindowStyle.Normal,
                    UseShellExecute = false,
                    CreateNoWindow = false
                };

                process.StartInfo = startInfo;
                process.OutputDataReceived += (sender, e) => Console.WriteLine(e.Data);
                process.Start();
                process.StandardInput.Write("script"+ process.StandardInput.NewLine);
                process.StandardInput.Write("exit" + process.StandardInput.NewLine);
                process.WaitForExit();
            }

This worked for me and the program execution waited till the script finishes.

Clicking problems with IE and Selenium

We were facing couple of problems with selenium tests running on IE, when running the tests locally, we don't have these issues. After adding more logs to the code, i found that sometimes it is failing after sending the click event in different steps. 

Looking online for similar issue, i found that there are clicking issues with IE, as sometimes the element being clicked on will receive the focus, but the click will not be processed by the element.

To workaround this, i am setting the focus manually to the browser using the below line of code

Driver.SwitchTo().Window(Driver.CurrentWindowHandle);
