After running dev-certs https --trust, dotnet run complains that the default developer certificate could not be found

We ran the following in PowerShell:

dotnet dev-certs https --clean
dotnet dev-certs https --trust
dotnet dev-certs https --check # none found :-(

Then we opened a new PowerShell session and ran this:

dotnet dev-certs https --check # still none found :-(
dotnet run

This is the error message.

System.InvalidOperationException: Unable to configure HTTPS endpoint. No server certificate was specified, and the default developer certificate could not be found or is out of date.

Here is the output of dotnet --info

How can we point dotnet run to the certificate that we created with dotnet dev-certs https --trust?

Solution

Based on https://stackoverflow.com/a/65266499/1108891, we manually deleted all certificates that localhost issued and then repeated our steps. This is how we deleted all localhost issued certs.

Get-ChildItem -Path Cert:\CurrentUser -Recurse `
| Where { $_.PSISContainer -eq $false } `
| Where { $_.Issuer -match 'localhost' } `
| Remove-Item -Whatif;

 Get-ChildItem -Path Cert:\LocalMachine -Recurse `
| Where { $_.PSISContainer -eq $false } `
| Where { $_.Issuer -match 'localhost' } `
| Remove-Item -Whatif

The -Whatif is there to avoid copy/paste from clobbering an unwitting reader's certificate store. We removed it when we ran this step.
