How model binding works: what sources it considers Model binding in ASP.NET Core maps incoming HTTP data to C# parameters or model properties. 🔍 Sources considered: ● Route data ● Query string ● Form data ● Headers ● JSON body (application/json) ● Uploaded files ● Services (via [FromServices])

Short answer: SP.NET Core automatically binds data based on parameter types and attributes ([FromBody], [FromQuery], etc.).

Real-world example (ShopNest)

ShopNest registers AppDbContext as Scoped and IMemoryCache as Singleton. Putting DbContext in a Singleton causes threading bugs.

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.
