MAUI is incompatible with .NET 7 so you might want to uninstall it. Got the same VS version and I got all the MAUI templates.

Thank you @Symbai , I think you're right.

If I add a global.json file and run dotnet new --list, then I see MAUI templates in the list: image

But I still cannot add MAUI projects in Visual Studio, only through the cli.

I would say that the issue is that Visual Studio doesn't show all the templates, from all the SDKs.

MAUI wants 6.0.300 and cause unpredictable problems when you have a newer .NET version / SDK installed. I suggest you uninstall that first as I told you and then check it again.

I have the same problem. I'm running Windows 11 on a Mac Studio, I dunno if that's the problem?

dotnet --version 6.0.300

When I look in Visual Studio 2022 Preview (17.3.0, 1.1) and search in templates for MAUI, or when I run dotnet new --list, I don't see anything about MAUI:

I'm trying to prep this summer for a class that I'm teaching in the fall, so any help would be greatly appreciated!

You might want to check it .NET 7 preview is installed (run dotnet --version), if that's the case the templates are installed but they won't show up. More info on that here.

If the templates are not installed you can run dotnet new -i Microsoft.Maui.Templates to still get them. Please do not use the version that is at the end, especially not the one as advertized here because that is an older version. If you do not specify a version the newest ones will be installed.

We're investigating why the templates are not installed in some instances and will fix that. Since we have multiple issues about this I'm closing this one. Please let us know if you still can't get the templates to show up.

@mprogers I hope this helps, if not, feel free to reach out to me directly so we can start helping that prep! We don't want to leave the students out in the cold!

Indeed that was my problem - I had preview 7 installed. It is very nice that you have that wiki page, thanks a lot!

I agree, the issue can be closed

Well ... now I can see templates in Visual Studio, but building a project produces a slew of errors about target platform identifiers not being recognized (android, maccatalyst, iOS ), and something about the Platform version not present.

Error | NETSDK1139 | The target platform identifier android was not recognized. | MauiApp1 | C:\Program Files\dotnet\sdk\6.0.300\Sdks\Microsoft.NET.Sdk\targets\Microsoft.NET.TargetFrameworkInference.targets | 112 |  

Error | NU1012 | Platform version is not present for one or more target frameworks, even though they have specified a platform: net6.0-android, net6.0-ios, net6.0-maccatalyst | MauiApp1 |

I am running this on Windows 11 over Parallels (for macOS), so maybe that's the problem. Interestingly, the Mac version of this worked fine, and on my office computer (Intel-based Mac running Windows 10) this isn't an issue.

I'm sure this is just something simple that I've neglected to do -- I do most of my development in Swift and Flutter -- so any suggestions (apart from give up and wait a year for it to come out of beta, I did that last year) would be appreciated!
