## Host Admin Dashboard with ASP.NET Core: Application Activity History

### Summary
Deploy an admin dashboard built with ASP.NET Core on Ample using the transactional workflows pattern. Compute runs the app in an isolated microVM behind a public HTTPS URL, with a managed PostgreSQL 16 database auto-provisioned and injected as `DATABASE_URL`. Verified on ASP.NET Core: an optimistic version check and an event row written in the same transaction, a stale update rejected, and a history query over the application-owned events (history=2 conflict=rejected). Not separately tested: your domain records, validation rules, and concurrency policy; treat the admin dashboard-specific behavior as your application code.

### Workload Requirements
- **Framework**: ASP.NET Core
- **Workload**: Admin dashboard
- **Release Status**: Published
- **Support Status**: Verified
- **Execution Status**: Ready

### 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.
- **Postgres**: Managed PostgreSQL 16 runs in its own microVM and is auto-provisioned when an app needs a database and no `DATABASE_URL` is supplied.

### Prerequisites
- An ASP.NET Core project that builds and starts with the documented commands (`dotnet publish -c Release -o out` in the builder, then `dotnet .dll` on the dotnet-10 template with `ASPNETCORE_URLS` bound to `PORT`)
- A PostgreSQL driver reading `DATABASE_URL` at runtime (auto-provisioned when omitted, or supplied with `--env`)
- An Ample account token with `servers:write`, `databases: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`.
2. **Implement the pattern on PostgreSQL**: Copy the transactional workflows approach into your schema; keep migrations idempotent and run them with `--release-command`.
3. **Deploy**: Run the synchronous deploy once and read the result.
4. **Verify**: Fetch the live URL and run your own checks.

### Success Checks
- App responds on its public URL
- Transactional-workflows self-test

### Limitations
- Verified on the dotnet-10 template at `s-1vcpu-1gb`; other sizes, templates, and ASP.NET Core major versions are not verified.
- The admin dashboard itself behavior is application code and was not separately tested.

### Cost Estimate
- **Currency**: USD
- **Monthly Amount**: $10.00
- **Components**:
  - App server: `s-1vcpu-1gb`, Quantity: 1.0, Monthly Amount: $5.0
  - Managed PostgreSQL database: `s-1vcpu-1gb`, Quantity: 1.0, Monthly Amount: $5.0
- **Note**: Always-on monthly price of the tested sizes; apps and databases auto-pause when idle.

### Evidence Summary
- ASP.NET Core pattern fixture deployed on Ample; checks passed for transactional-workflows and configuration-secrets.
- Summary of checks includes optimistic version check and event row transactions.
