I get that there are solutions to the problem, but there’s no way a team of 10 can port 35 years of win32 dependence and keep the business solvent. Maybe incrementally, over the course of 10-15 years. We’re just now migrating off of .NET 4.8 because we use WCF so much.
Some places are inextricably tied to SimuLink due to how long it was around before any of the alternatives.
