Languages:

I learned , my first programming language, 2 years ago and developed projects. But I've taken a break from for now.

After , I learned , but I did not develop many projects.

4 months ago, the idea of developing command line tools came to my mind. I heard that the language has very good packages for developing command line tools and I started learning it right away. I wrote small command line tools in . I still use this language.

I learned with Linux. I wrote beautiful scripts with this language.

I'm new to the programming language. I started learning 3 weeks ago (August 20). It caught my attention that it has been chosen as my favorite programming language many times on StackOverflow. The community also said that this language is very good. I started learning right away. Indeed, as the community says, is a powerful and beautiful language.

I use as my main version control tool. The best in its field.

Selecting only a number and operator will cause a FormatException when calculating the result

I saw your reddit post, neat project. I wanted to check it out, so I cloned it and did some testing. I found an immediate issue.

If you select a first number (let's say 9), an operator (let's say add) and immediate go to calculate the result, a FormatException will occur at this line:

https://github.com/AlperAkca79/dotNETCalculator/blob/05ccae288a6bf4ffd85888e0754e30ac3705d44a/dotNETCalculator/MainWindow.xaml.cs#L212

While I could implement a safer way to patch it up, a very quick and dirty work around would be to change it to

if (string.IsNullOrWhiteSpace(output))
    output = temp.ToString();

PreviewOutput.Text = (temp.ToString() + " " + operation + " " + double.Parse(output) + " " + "=");
...

A default behavior could be that the input value should be subject to both sides of the calculation when doing (basic) operations. That way, 9+= would be 9+9=18.
