Visual Studio for Mac 上的 .net-core3.1：无法配置 HTTPS 端点

Question

On my Mac, Visual Studio throws this error when I try to run a .net core project.

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 No server certificate was specified, and the default developer certificate could not be found or is out of date.\\nTo generate a developer certificate run 'dotnet dev-certs https'. To trust the certificate (Windows and macOS only) run 'dotnet dev-certs https --trust'.\\nFor more information on configuring HTTPS see https://go.microsoft.com/fwlink/?linkid=848054."

Running: dotnet dev-certs https

Returns:

A valid HTTPS certificate with a key accessible across security partitions was not found. The following command will run to fix it: 'sudo security set-key-partition-list -D localhost -S unsigned:,teamid:UBF8T346G9' This command will make the certificate key accessible across security partitions and might prompt you for your password.

The following command will run to fix it: 'sudo security set-key-partition-list -D localhost -S unsigned:,teamid:UBF8T346G9' This command will make the certificate key accessible across security partitions and might prompt you for your password. For more information see: https://aka.ms/aspnetcore/3.1/troubleshootcertissues A valid HTTPS certificate is already present.

Running: sudo security set-key-partition-list -D localhost -S unsigned:,teamid:UBF8T346G9

Prompts for two passwords:

password to unlock default:

and then returns:

security: SecKeychainItemSetAccessWithPassword: The user name or passphrase you entered is not correct.

I have also deleted my localhost certificate and generated a new one.

What else should I try?

Answer 1

This worked for me :

• Open Keychains
• Click on System / Certificates
• find the cert for localhost
• right click and delete
• go to your terminal enter dotnet dev-certs https --trust
