[severity:It bothers me. A fix would be nice]
I have an project for fsharp, it is Microsoft.NET.Sdk with targetframework net6.0-windows. When I right click the project in the solution explorer, and click properties, I can scroll down to the "Errors and warnings". The Warning level is default set to 3. From the dropdown menu, it gives the option to set it to "7 - Warnings from C# 11". When I select this option, and build the project, it wails with an error:
Severity Code Description Project File Line Suppression State
Error FS1050 Invalid warning level '7' ProjectName C:\Users\username\foldername\Documents\foldername\Products\projectname\src\solutionname\projectnamei\FSC 1 Active
