dotnet-devcert-trust

separate

Diagnose and fix .NET HTTPS dev certificate trust issues on Linux. Covers the full certificate lifecycle from generation to system CA bundle inclusion, with distro-specific guidance for Ubuntu, Fedora, Arch, and WSL2.

When to use

• Redis TLS connections fail with `UntrustedRoot` or `RemoteCertificateNameMismatch` in Aspire
• `dotnet dev-certs https --check --trust` returns exit code 7
• HTTPS localhost connections fail with certificate validation errors
• After running `dotnet dev-certs https --clean` and needing to restore trust
• Setting up a new Linux dev machine for .NET HTTPS development
• Aspire dashboard or inter-service gRPC calls fail with TLS errors
• Upgrading from Aspire < 13.1.0 (which didn't use TLS on Redis by default)
