How to debug the samples of this project?

[john-dalsgaard]

Hi

I feel I must be doing something wrong. I have downloaded the entire project as a zip and unpacked it on my Mac. Then I have opened the folder "samples" in my VS Code. I have set the debug info to:

and try to run it. When I have Android selected I get these errors on trying to debug the samples:

I have cleaned the project before I try to run it - and removed bin and obj folders.

If I try to run it on an iPhone16 Pro simulator or my Mac I get only one error:

/Users/jda/Downloads/Maui-main2/samples/CommunityToolkit.Maui.Sample/Platforms/iOS/AppDelegate.cs(6,28): error CS0246: The type or namespace name 'MauiUIApplicationDelegate' could not be found (are you missing a using directive or an assembly reference?) [/Users/jda/Downloads/Maui-main2/samples/CommunityToolkit.Maui.Sample/CommunityToolkit.Maui.Sample.csproj::TargetFramework=net8.0-ios]

But nevertheless I cannot run the project.

So what am I doing wrong here??? I have tried to look for extra steps to carry out when trying to run the samples but have not been able to find them.

I have the .net 8 SDK installed:

6.0.428 [/usr/local/share/dotnet/sdk]
7.0.317 [/usr/local/share/dotnet/sdk]
8.0.404 [/usr/local/share/dotnet/sdk]
9.0.100 [/usr/local/share/dotnet/sdk]

I have the following workloads installed:

Workload version: 8.0.404.1

Installed Workload Id      Installation Source
----------------------------------------------
wasi-experimental          SDK 8.0.400        
ios                        SDK 8.0.400        
maccatalyst                SDK 8.0.400        
maui                       SDK 8.0.400        

Use `dotnet workload search` to find additional workloads to install.

Updates are available for the following workload(s): wasi-experimental ios maccatalyst maui. Run `dotnet workload update` to get the latest.

I have run sudo dotnet workload update and restarted VS Code, so not sure why it keeps stating that there new updates? Anyway, I would not think they had anything to do with the .NET MAUI code...

Any help appreciated as I need to get Popups running on Android as well. Apparently, my solution only works on iPhone at the moment... ;-)

In the root folder, there is a file global.json. In there, it details the exact SDK version needed by the toolkit. At time of writing, this is:

{
  "sdk": {
    "version": "9.0.102",
    "rollForward": "latestFeature",
    "allowPrerelease": false
  }
}

As such, you NEED to have specifically 9.0.102 installed.

I had 9.0.201 installed and had problems, had to install 9.0.102 specifically...AND reboot my computer to get it to work.

You can remove global json file for local development. Or simple change allow prerelease to true
