Soft Skills

I've had a problem with building our primary application today. Yesterday was a day of upgrades; I installed both Visual Studio 2019 16.11 and Visual Studio 2022 Preview 3 - all the new bits. Today, an application I was working on wouldn't build. We were getting error CS1576 - 'The line number specified for #line directive is missing or invalid' in relation to the code that is auto-generated for Blazor components.
