Let’s begin.

⭐ How Image Upload Works in ASP.NET Core 8

ASP.NET Core uses IFormFile to receive files from the client (Postman, form, frontend apps).
You can save uploaded images in two ways:

? Option 1: Save Image in Folder (Recommended for performance)

Store only filename/path in the database.

? Option 2: Save Image in Database (Good for APIs & portability)

Store actual bytes in the DB.

We will implement both methods so you can choose based on your project.

? Step 1: Create Model Class

? Models/ProductModel.cs

?️ Step 2: Create Folder for Image Uploads

Inside your project:

wwwroot/uploads

If wwwroot is missing → Right-click project → Add → New Folder → Name it wwwroot.

Inside wwwroot → Add folder → uploads

? Step 3: Configure Program.cs for Static Files

In Program.cs:

app.UseStaticFiles();

This allows images inside wwwroot to be accessed via URL.

? Step 4: Create Service for Image Upload

? Services/ImageService.cs

builder.Services.AddScoped();

? Step 5: Create API Controller

? Controllers/ProductController.cs

}

Then open the image in the browser:
