Description

I'm running macOS (Sonoma 14.6.1), VSCode (1.94.0) with the .NET MAUI extension (v1.3.29). I think I've got the .NET version that was just released --

and should be compatible with Xcode 16.

But when I try and build a new .NET MAUI application, I'm getting a bunch o' error messages that I cannot decipher. It says I've got the wrong SDK Version, but instead of telling me what version it is, it's writing <DVTBuild Version *>, so I'm not sure what I need to do.

Here are the error messages:

Can someone please point me in the right direction? I really, really miss my iOS simulator:

The problem is that your macOS machine doesn't have the iOS platform component installed.

The platform component can be installed using Xcode, see here for a description: https://github.com/xamarin/xamarin-macios/wiki/Known-issues-in-.NET8#the-build-fails-with-no-simulator-runtime-version-from-
