AgentBlazor 0.2 — what changed since the April preview
I posted about AgentBlazor on here three weeks ago when 0.1 went on NuGet. Shipping 0.2.0 today and wanted to share what changed, since most of it came directly from feedback on the original threads.
Live demo (no install): https://demo.agentblazor.com/
The architectural argument hasn't changed: the LLM operates your Blazor app through the typed C# methods you've already written, not by getting database access or generating SQL. The pitch is narrow — one route, one chat surface, one capability class, one deterministic UI change after the prompt.
The demo now uses a support queue because the behaviour is concrete. This morning I asked the agent to draft replies for three highlighted tickets. One came back blocked: "TCK-1055 is missing order evidence, so the reply needs escalation first." The workflow's check held. The agent didn't bypass the gate or fabricate evidence — it surfaced the block and stopped.
That's the trust boundary v0.2 is built around. Your typed methods are the agent's contract.
What's new since April:
Structured capability errors with LLM-readable recovery hints (instead of raw exceptions that make the agent spiral)
Schema-only entity exposure via optional AgentBlazor.EntityFrameworkCore — agent reasons about allowlisted EF entities as planning context, can't query the DB directly
Cleaner install path: dotnet add package AgentBlazor (no more swap-files-in-order starter)
Hosted demo with structured per-turn logging
Six package fixes from the April feedback (ambiguous endpoint method, misleading "default agent" copy, friendlier exception when API key missing, shell rendering logic, etc.)
Honest limits:
Preview-grade overall, MudBlazor-first for built-in wrappers
OpenAI is the default provider today
Built on Microsoft Agent Framework (GA core + preview hosting transport)
Multi-library wrapper support (Radzen, Telerik, etc.) is v0.3 work
Install: dotnet add package AgentBlazor Repo: https://github.com/ashpeterson/AgentBlazor Quickstart: https://github.com/ashpeterson/AgentBlazor/blob/master/docs/quickstart.md
Happy to answer questions about the architecture, the trust-boundary design, or what shipping the April feedback cycle taught me about building this in the open.
