microsoft-code-reference

Original：🇺🇸 English

Not Translated

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.

Tools

Need Tool Example

API method/class lookup

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` (for overloads, full signatures)

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

(for overloads, full signatures)

Finding Code Samples

Use

microsoft_code_sample_search

to get official, working examples:

microsoft_code_sample_search(query: "upload file to blob storage", language: "csharp")
microsoft_code_sample_search(query: "authenticate with managed identity", language: "python")
microsoft_code_sample_search(query: "send message service bus", language: "javascript")

When to use:

Before writing code—find a working pattern to follow
After errors—compare your code against a known-good sample
Unsure of initialization/setup—samples show complete context

API Lookups

# Verify method exists (include namespace for precision)
"BlobClient UploadAsync Azure.Storage.Blobs"
"GraphServiceClient Users Microsoft.Graph"

# Find class/interface
"DefaultAzureCredential class Azure.Identity"

# Find correct package
"Azure Blob Storage NuGet package"
"azure-storage-blob pip package"

Fetch full page when method has multiple overloads or you need complete parameter details.

Error Troubleshooting

Use

microsoft_code_sample_search

to find working code samples and compare with your implementation. For specific errors, use

microsoft_docs_search

and

microsoft_docs_fetch

:

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"`

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

Before generating code using Microsoft SDKs, verify it's correct:

Confirm method or package exists —

microsoft_docs_search(query: "[ClassName] [MethodName] [Namespace]")

Fetch full details (for overloads/complex params) —
```
microsoft_docs_fetch(url: "...")
```

Find working sample —

microsoft_code_sample_search(query: "[task]", language: "[lang]")

For simple lookups, step 1 alone may suffice. For complex API usage, complete all three steps.
