Error checking stops working when ApplicationIcon property inside fsproj is set.

[marcpiechura]

Describe the bug

When adding the <ApplicationIcon>Logo.ico</ApplicationIcon> property to the <PropertyGroup> inside the fsproj, error checking stops working and works again once the property gets removed again.

Steps to reproduce

• Create simple console application via dotnet new
• Add <ApplicationIcon>Logo.ico</ApplicationIcon> to the fsproj

Expected behaviour

Error checking should work even if the ApplicationIcon is defined

Total shot in the dark, but have you tried the latest SDK SDK 5.0.400?

ApplicationIcon had some problems with the compiler until somewhat recently, but I honestly can't say for sure which SDK release shipped a compiler with the updates to make it recognized.

@cartermp thanks for the quick response. Tried it right now, but unfortunately with the same outcome.

Gah, bummer. Confirmed that this does work in Visual Studio, so at least it's not an upstream problem.

Try ">developer reload", or close file, close folder, and reopen? This is a different setting, but it looks like the same scenario as described here #1500. Seem booksbaum's example.

Thanks for the suggestion, but my issue seems to be much more persistent, it either works or it doesn’t work. Before I figured out what was causing the issue, I even tried to restart my PC, unfortunately without any affect, only after this I started to undo my recent changes until it worked again.

Just wanted to mention that I've had the same problem where Error checking stoped working.
Commented out the <ApplicationIcon> and it started working again.

Tested on two different Windows clients.
