How can you access Azure services from a .NET Core application?

Short answer: By using Azure SDKs or REST APIs. Use Azure Identity for authentication. Example for Azure Blob Storage: using Azure.Storage.Blobs;

Example code

var blobServiceClient = new BlobServiceClient("<connection_string>"); var containerClient = blobServiceClient.GetBlobContainerClient("mycontainer"); await containerClient.UploadBlobAsync("sample.txt", new BinaryData("Hello Azure!"));

Real-world example (ShopNest)

ShopNest on Azure typically uses App Service + SQL Database + Blob Storage + Application Insights for monitoring.

Say this in the interview

1. Define — one clear sentence (the short answer above).
2. Example — relate it to a project like ShopNest or your real work.
3. Trade-off — when you would not use it.
