Hey guys I am having an issue installing the Avalonia templates. "Avalonia.Templates could not be installed, the package does not exist."
Has anyone else had this issue? I have installed the latest version of .net 8 and still having this same issue.

Do you have changed something in your nuget.config?
Also can you try running it in a folder that is not a system folder?

[kwc81]

No I have not changed anything and I also tried running in outside the system folder still no luck
Can you help Id love to get started testing the avalonia ui for a new project.

[kwc81]

Is there something simple I am missing here. I am following these instructions here...https://docs.avaloniaui.net/docs/get-started/install.

Should be just a simple copy and paste of each command into power shell correct?

[Mrxx99]

yes that should work, unfortunately I don't know how to help here as I don't know and can't reproduce that error,
you can maybe run dotnet --info in the same folder you are running the install command, and if you are not on the latest patch version of .NET 8 you can try installing the latest. If this does not help you can clone the template repository and run the install-dev-templates.ps1 script. Also if you are using Visual Studio you can install the Avalonia Template Studio which gives you a template wizard in Visual Studio

Hi @kwc81 I have exacly the same problem in my Windows 11 machine. I've tried to lauch the command in my personal c:\User<my user> folder but without success either

[vittoso]

I fixed it... I am on a new PC and for some reason I didn't have the NuGet.org feed configured. I manually added Nuget.org https://www.nuget.org/api/v2/ into Nuget options packages source in Visual Studio 2022 and then the dotnet new install Avalonia.Templates command worked.

All credits to this SO answer.

Same issue, new laptop, fresh install of VS2022, no nuget feed configured. Thanks.

I had the same issue as well

thank you for this! I had the same issue. They should probably include this in the installation instructions
