dotnet
.dib is already a registered file extension in Windows
Describe the bug
Double clicking on a .dib file has Windows 10 to try to open it the Photos app.
Screenshots
Also when a .dib file is checked in to an Azure DevOps repository it thinks it's a binary image file.
I added *.dib text to my .gitattributes but it did not change anything.
Note that git itself recognizes .dib notebook files as text correctly, I can make local diffs, etc. GitHub also shows them as text correctly. It might be Azure DevOps that makes some kind of .dib -> image/bmp mapping.
Anyways, it might not be a good idea to reuse a well-known extension as it can lead to problems (ok, by well-known I mean "I never ever heard of it before I ran into this issue, but when I looked it up Wikipedia said .dib extension can be used for Device Independent Bitmap files, usually known as .bmp files in the Windows world").
Also on GitHub README.ipynb is rendered nicely but README.dib not. I don't think it's a good idea to use an extension that is already reserved by another existing format. Ideally this should be changed to something that is available like for example ".mdnb" for markdown notebook.
If you associate .dib with VS Code it will open there in the appropriate extension.
