What is this?
Store connection strings in Key Vault/User Secrets — never in source or plain config committed to git.
Why should you care?
ShopNest credential leaks start with checked-in passwords.
See it live — copy this example
Use a .NET console or API project with SQL Server LocalDB. Run dotnet run after pasting.
builder.Configuration.AddAzureKeyVault(new Uri(vaultUri), new DefaultAzureCredential());
var cs = builder.Configuration.GetConnectionString("ShopNestDb");What happened?
- Key Vault / MI.
- Rotate and ClearAllPools.
- Least-privilege SQL users.
Practice next
- Move CS to Key Vault.
- Local User Secrets.
- Rotate password.
- SQL auth → AAD.
- Audit who read the secret.
Remember
Vault/secrets. Rotate + clear pools. Least privilege.
ShopNest Key Vault CS
API loads CS from vault.
Outcome: Git stays clean.
