# Microsoft Code Reference

> Look up Microsoft API references, find working code samples, and verify SDK code is correct. Use when working with Azure SDKs, .NET libraries, or Microsoft APIs to find the right method, check parameters, get working examples, or troubleshoot errors. Catches hallucinated methods, wrong signatures, and deprecated patterns by querying official docs.

# Microsoft Code Reference

## Tools

| Need | Tool | Example |
|------|------|---------|
| API method/class lookup | `microsoft_docs_search` | `"BlobClient UploadAsync Azure.Storage.Blobs"` |
| Working code sample | `microsoft_code_sample_search` | `query: "upload blob managed identity", language: "python"` |
| Full API reference | `microsoft_docs_fetch` | Fetch URL from `microsoft_docs_search` result |

## When to Verify

Always verify when:
- Method name seems "too convenient" (`UploadFile` vs actual `Upload`)
- Mixing SDK versions (v11 `CloudBlobClient` vs v12 `BlobServiceClient`)
- Package name doesn't follow conventions (`Azure.*` for .NET, `azure-*` for Python)
- Using an API for the first time

## Validation Workflow

1. **Confirm method exists** — `microsoft_docs_search(query: "[ClassName] [MethodName] [Namespace]")`
2. **Fetch full details** (for overloads) — `microsoft_docs_fetch(url: "...")`
3. **Find working sample** — `microsoft_code_sample_search(query: "[task]", language: "[lang]")`

## Error Troubleshooting

| Error Type | Query |
|------------|-------|
| Method not found | `"[ClassName] methods [Namespace]"` |
| Type not found | `"[TypeName] NuGet package namespace"` |
| Wrong signature | `"[ClassName] [MethodName] overloads"` → fetch full page |
| Deprecated warning | `"[OldType] migration v12"` |
| Auth failure | `"DefaultAzureCredential troubleshooting"` |
| 403 Forbidden | `"[ServiceName] RBAC permissions"` |
