You know how you can click on an image and change the default image viewer it opens in ?
like change it from Photo to paint
how do I make my C# Photo app be the Default viewer ? because when I installed it, it did not come up as an option.
also do I have to add anything to my program so that you can just double click on an image and it would open right ?

Step 1. Click on the Start button, searchChoose a default app for each type of file.
Step 2. You are on the “choose defaults by file type” page where just enter common images file extensions such as JPG, PNG, and BMP. Click on the button which is the default app for that extension.
Steps 3. Click Always use the app to open .jpg files which will set it as the default image app. This will set the Windows Photo Viewer as the default program for the particular image extension. Repeat this for more images extensions.
