Why should you care?

Skipping setup causes mysterious build errors later. One afternoon here saves weeks of frustration.

See it live — copy this example

Create a Web API (dotnet new webapi), paste the example, run dotnet run, test in Swagger.

dotnet --version
# Install from https://dotnet.microsoft.com
# SQL Server + SSMS for EF Core lessons

Run Example »

This lesson uses terminal or setup steps. Run commands on your computer — the live editor appears on coding lessons.

What happened?

• Match versions: use LTS .NET SDK, SQL Server Developer edition, and latest Postman for local testing.
• Follow the practice steps below on ShopNest.API — typing code yourself is the fastest way to learn.

Try it yourself

1. Read what .NET Core vs .NET Framework Code Execution Process means for ShopNest.API.
2. Type the example — do not only copy-paste.
3. Test in Swagger or Postman.
4. Change a route URL or DTO property and save — test again in Swagger or curl.
5. Return the wrong status code on purpose (404 instead of 200) and see what the client shows.

Remember

You understand .NET Core vs .NET Framework Code Execution Process in plain language. You traced or ran working C# in ShopNest.API. Move on when you can teach this topic to a friend.
