# Deliver public assets through CDN for ASP.NET Core

### Summary
Cdn assets for a ASP.NET Core app on Ample. Verified on ASP.NET Core: a versioned, immutable-cached asset uploaded to a published bucket and served from the CDN URL. Build and start: `dotnet publish -c Release -o out` in the builder, then `dotnet .dll` on the dotnet-10 template with `ASPNETCORE_URLS` bound to PORT.

### Representative Queries
- Deliver public assets through CDN for ASP.NET Core
- Where can I host Deliver public assets through CDN built with ASP.NET Core?
- I need a public-origin configuration, versioned asset build and observable cache behavior.

### Resource Requirements
- **Compute**: Apps run in isolated x86_64 Firecracker microVMs that auto-pause when idle and wake on request; sizes are the priced VM sizes.
- **CDN**: The CDN host serves objects from published buckets. It does not front app compute and is not a cache or key-value store.

### Workload
Deliver public assets through CDN

### Prerequisites
- A ASP.NET Core project (`dotnet publish -c Release -o out` in the builder, then `dotnet .dll` on the dotnet-10 template with `ASPNETCORE_URLS` bound to PORT)
- A bucket from `ample bucket create` with credentials passed as encrypted S3_* environment variables.
- An Ample account token with servers:write, buckets:read.

### Workflow Steps
1. **Build and start**  
   `dotnet publish -c Release -o out` in the builder, then `dotnet .dll` on the dotnet-10 template with `ASPNETCORE_URLS` bound to PORT; the server must bind `0.0.0.0` on PORT.
2. **Publish a bucket for public assets**  
   Publish only the asset bucket; upload versioned keys with an immutable Cache-Control header and build URLs from its public URL.
   Command: `ample bucket publish`
3. **Verify**  
   Fetch the live URL and `/p/versioned-static-assets` on the example; on failure read the build and runtime logs.  
   Command: `ample logs --kind build`

### Examples
- **ASP.NET Core pattern fixture**: Verified CDN assets on ASP.NET Core.

### Success Checks
- App responds on its public URL.
- Versioned-static-assets check from the example.

### Limitations
- Verified on the dotnet-10 template at s-1vcpu-1gb; other sizes and ASP.NET Core major versions are not verified.
- Region, compliance attestations and request-duration limits are unknown and not claimed.
- The CDN serves published-bucket objects only; cache rules, purge and TTL control are not verified.

### Cost Estimate
- **Monthly Amount**: $5.00 (USD)
- **Note**: Always-on monthly price of the tested sizes; apps auto-pause when idle. Buckets are allocation-priced per quota and not included.

### Evidence Summary
- **ASP.NET Core pattern fixture** deployed on Ample; a versioned, immutable-cached asset uploaded to a published bucket and served from the CDN URL.
