OpenID Metadata not getting cached #53049
Description
After upgrading my .net 8 Project to .net 9 or .net 10 I have issues with OpenID Metadata not getting cached when validating an Entra Token.
Each request the OpenID data get fetched again.
Performance before uprading:
After upgrading to newer .net including new Authentication.JWTBearer Package
Before Upgrade:
Request to /usageTypes took 139ms.
Breakdown: PreAuth: 0,05ms,
Validation: 0,16ms,
Endpoint: 139,38ms.
After Upgrade
Request to /usageTypes took 456ms.
Breakdown: PreAuth: 30,96ms,
Validation: 248,30ms,
Endpoint: 176,93ms
My program.cs configuration is very basic. Nothing special:
I can fix it by either downgrading to .net 8 or precaching the configManager:
The endpoint is also very simple
To Reproduce
In my case, just use any entra configuration with
builder.Services.AddAuthentication(JwtBearerDefaults.AuthenticationScheme) .AddMicrosoftIdentityWebApi(builder.Configuration.GetSection("AzureAd"));
I tested it on different devices (same issue).
"AzureAd": { "Instance": "https://login.microsoftonline.com/", "TenantId": "xxxxxx", "ClientId": "yyyyy", "CallbackPath": "/signin-oidc" },
