Call APIs, load data into components, and handle the async lifecycle in Blazor. USE FOR fetching data from a backend, submitting data to an API, displaying loading/error states, registering HttpClient, building service abstractions for Auto/WebAssembly render modes. DO NOT USE for form validation (see collect-user-input), prerendering persistence (see support-prerendering), or project scaffolding (see create-blazor-project).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Fetch and Send Data
## Step 1 — Read AGENTS.md
Check **Interactivity Mode** and **Scope**:
| Mode | Data access |
|------|-------------|
| None (Static SSR) | Server-side: inject services/`DbContext`. Use `[StreamRendering]` for loading UX. |
| Server | Server-side: inject services/`DbContext`. Guard prerender with `??=` + `[PersistentState]`. |
| WebAssembly | Browser-side: `HttpClient` only. No direct server access. |
| Auto | Both server and browser. Always go through an API. |
## Step 2 — Register HttpClient
Only needed when calling external APIs from Server, or always for WebAssembly/Auto. Server components accessing their own database should inject `DbContext` or a service directly.
```csharp
// Named client — requires Microsoft.Extensions.Http NuGet
builder.Services.AddHttpClient("CatalogAPI", client =>
{
client.BaseAddress = new Uri("https://api.example.com/");
});
// Typed client
builder.Services.AddHttpClient<CatalogClient>(client =>
client.BaseAddress = new Uri("https://api.example.com/"));
```
For WebAssembly/Auto with prerendering, register in **both** server and `.Client` `Program.cs`.
## Step 3 — Fetch Data
### Simple load
```razor
…Read the whole file at its exact version.
How to install
mdr add dotnet/skills/fetch-and-send-data@sha256:7af26f6f75d8f952The line at the top of this page pins the label git:20260525.198e58c, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
