I was having this issue initially. I was able to resolve them after I upgraded my project to .NET Aspire 9.0 (RC 1) - you can see the upgrade guide here

megashrieks commented 1 week ago

@kylejuliandev this seems to fix the frequency of the errors, but the error still persists.

joperezr commented 1 week ago

We released .NET Aspire 9.0.0 earlier today, would you be able to update to that stable version and see if the issue persists?

dovijoel commented 1 week ago

I updated my project to Aspire 9.0 and started encountering this issue as well. I am on Windows 11 using Docker Desktop.

AwkEng commented 1 week ago

I was getting the same error on my desktop machine, but worked fine on my laptop. Both are running Win11 and Docker Desktop. I ended up reinstalling Docker Desktop on my desktop and that seemed to fix my issue.

ITedInnovator commented 1 week ago

I had the same problem with Redis when following the learn-dotnet-aspire tutorial. I updated Docker Desktop and now it is working.

Also, it might have been restarting WSL fixed the issue.

dotnet / aspire
