Mac with Apple Silicon: The Aspire application host is not installed at /Users/<user>/.dcp/dcp

kavatari commented 5 months ago

Installed dotnet 8.0.1
installed aspire using (dotnet workload install aspire)
created a host project with a simple builder, trying to run the application in debug mode.
Docker is up and running
I am using Jetbrains Rider.

The following exception pops up:

Microsoft.Extensions.Hosting.Internal.Host[11]
      Hosting failed to start
      System.IO.FileNotFoundException: The Aspire application host is not installed at "/Users/<user>/.dcp/dcp". The application cannot be run without it.
      File name: '/Users/<user>/.dcp/dcp'

Do I miss some setup?

@kavatari can you double check if you have the build property <IsAspireHost>true</IsAspireHost> set in your host .csproj? That property is required to activate the Aspire workload for the host project (and the workload not loading is the most likely thing that could cause that particular error).

kavatari commented 5 months ago

@danegsta thanks for the hint, I totally forgot about this one. I added the property, now there is an other error:

I executed the following command: "botnet workload restore", but it show me still that aspire workload is not installed.

Successfully installed workload(s) aspire.

Currently, I think the dotnet installation might be not ok? Got also the same error for the aspire-samples/eShopLite solution.

edit: just tested my solution on my Windows machine, works like a charm.

@kavatari can you run dotnet —list-sdks and dotnet workload list and share the output?

kavatari commented 5 months ago

dotnet --list-sdks 8.0.101 [/opt/homebrew/Cellar/dotnet/8.0.1/libexec/sdk]

dotnet workload list is not showing any workloads installed...this will be the problem.

Right now, I am curious about the following output when installing the workload for aspire. Is this a normal behaviour?

I’ve got a Mac, but haven’t tried installing the SDK via homebrew on it; when I’m back in the office on Monday I’ll try it out and see if I can reproduce this workload behavior. I’m wondering if it’s an elevated vs unelevated file permission issue; homebrew usually installs applications unelevated, but most of the sdk workload commands assume they have to be run elevated. I know I’ve seen other workload install issues related to that before.

Running with -v diag should give more information on what went wrong: dotnet workload restore -v diag

kavatari commented 5 months ago

@danegsta it is definitely a homebrew problem. Maybe it would be still interesting to know what has to be done for the homebrew installation.

homebrew uninstall dotnet

dotnet --list-sdks

6.0.202 [/usr/local/share/dotnet/sdk]
7.0.400 [/usr/local/share/dotnet/sdk]
8.0.100 [/usr/local/share/dotnet/sdk]

Now, .NET Aspire workload can be found and I can run my solution.

dotnet workload list 

Installed Workload Id      Manifest Version                     Installation Source
-----------------------------------------------------------------------------------
aspire                     8.0.0-preview.2.23619.3/8.0.100      SDK 8.0.100        

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

This is something that needs be addressed in the .NET SDK. Will need to open an issue there.

dotnet / aspire
