Describe the bug

Currently trying to run my existing .net aspire app in Fedora Linux. This project is currently working in windows and on the our Ubuntu build server.

When I try to start up the project I get the following exception stack track:

System.AggregateException: One or more errors occurred. (Property DashboardPath: The path to the Aspire Dashboard binaries is missing.)
 ---> Microsoft.Extensions.Options.OptionsValidationException: Property DashboardPath: The path to the Aspire Dashboard binaries is missing.

Here are my launch settings:

  "profiles": {
    "https": {
      "commandName": "Project",
      "dotnetRunMessages": true,

        "DOTNET_RESOURCE_SERVICE_ENDPOINT_URL": "https://localhost:22188"
      }
    }
  }
}

When I list the dotnet workloads, I get this:

dotnet workload list

Installed Workload Id      Manifest Version                     Installation Source
-----------------------------------------------------------------------------------
aspire                     8.0.0-preview.1.23557.2/8.0.100      SDK 8.0.100        

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

Updates are available for the following workload(s): aspire. Run `dotnet workload update` to get the latest.

Running the command dotnet workload update says it updated it, but does not report as updated.

Expected Behavior

For the app to start up and show me the dashboard.

Steps To Reproduce

Run dotnet run for the apphost project

You have a really old aspire workload version installed.

Right. Can you please run:

dotnet workload update
dotnet workload install aspire

@joperezr - This is really confusing. Running those commands doesn't appear to change anything.

I was able to find a workaround with this. For whatever reason something is messed up with the version of .net that is install on my machine and I don't have a built in mechanism to update dotnet to the latest version.

My workaround here is to run through the dotnet install script guide here: https://learn.microsoft.com/en-us/dotnet/core/install/linux-scripted-manual#scripted-install

This install a newer version of dotnet in my /home directory. I installed the latest workload via that dotnet install and then pointed Jetbrains Rider to use that version. Now, I'm back up and running.

We've removed workloads from aspire 9 👍🏾
