The whole discussion around why a .NET shop might choose Blazor over Javascript ecosystem misses these critical things when it comes to developer experience:
1. Antivirus scans — it will take a lot more time for an antivirus to scan the tens of thousands of files in node_modules than whatever dotnet is doing. Especially on Windows
2. Corporate proxy support — the story of proxy support and importing custom certificates for the MITM proxy is still pretty much horrible (although improved since middle-2010s) in the Javascript ecosystem. dotnet is not perfect here and still has some warts in some specific tools, but much much better.
