Hide errors on projects in solution explorer?

The feature that underlines the items with errors in `Solution Explorer` is being called `Solution Wide Analysis`. You are free to disable it via a green checkmark in the bottom-right corner of the Rider.
You can remove the white line by disabling the checkbox: `File | Settings | Editor | General | Appearance | Show hard wrap and visual guides`.

Thank you so much!

Is there any possibility to remove only the read lines from the Solution Explorer without disabling Solution Wide Analysis.

Like you can i the code window with the pens  and setting what severity you what to show.

Seems kind of odd if i have one setting that is Highlight Level Error that only applys in Code Files. I and cant see any error in the File in the code window but the file is still red in the solution explorer because it has som kind of fault that is below Error Level.

Hello Mattias,

Thank you for contacting Rider support.

Solution-Wide error Analysis is what allows Rider to keep track of all errors/warnings in your solution, so you do not have to open every file to check if it contains any errors/warnings. When you disable the SWEA, highlighting will disappear from the Solution Explorer.

Regrettably, there is no way to disable errors highlighting in Solution Explorer view while having the Solution-Wide Analysis feature enabled. 
Should you have any questions, please let me know.

Have a nice day!
