MAUI Template not showing up in VS 17.5.2

[JerryWatsonJr]

After updating to 17.5.2 my maui projects will not open. When try to create a new solution the maui template does not show. I am using Windows 10.

If you go to your CLI and type dotnet new --list do you see the MAUI templates? If not, can you run dotnet workload install maui?

did you try to update the window?

The error is very strange with the workload install, but it seems the workload is installed. Could you try to just to dotnet new install Microsoft.Maui.Templates? That should only install the templates and also make them show up in Visual Studio.

I have wasted enough time. I just changed to 17.4.2 and everything works. Thanks

I also had this issue. I figured out that there where two dotnet SDK path version listed in my environment variables somehow after the update.
There I deleted the entry leading to the Program Files (x86). After that, VS took the right SDK and it was working again.
Maybe it helps you as well ;)

I do not have two, only Program Files (not x86). Thanks anyway.

As also communicated per email:

Seems like you’re made a backup just to be sure in that folder. Which is a very wise thing to do! But in this case that breaks it. Notice how it says it tries to make a numeric identifier from 300_bak which is obviously not an integer 😊

Either rename that back, delete the folder, or use the safest option and move the folder outside of that folder.

Well I installed 17.5.3 on my other laptop and it works. So there is something installed on the other laptop that is causing the problem.
