Yes indeed, you mentioned that a few months ago, and it happened to me a few days ago. I opened a project archived about last Xmas to compare some code with its replacement and I received shedloads of errors trying to compile and run it, I could have spent a solid hour resurrecting it with tfm or package updates, but I gave up and just browsed the raw files. Sometimes projects I compiled last Friday won't work this week.

The person who should be taken to the Hague and prosecuted for crimes against software is Mr Newtonsoft. I wonder if other people here have burned major parts of their lives away trying to solve Newtonsoft conflicts and crashes. He's not totally to blame though, because major players have become dependent on it, which combined with its dodgy versioning system has created a tangle worse than string theory. I'm glad to see Microsoft is gradually removing it from their libraries, the worst being Cosmos DB which keeps dragging it in (but I think it's gone in the latest libraries I'm not using yet). End of rant.

P.S. I just found that one of my vanilla hobby Blazor apps is also stalling like the big apps. Now I suspect there is some new global compatibility or config mismatch issue. The only players are VS2022 and Chrome, so what they hell has happened to their friendship?!
