What is this?
You need the .NET SDK (command-line tools and runtime) to build MVC apps. Visual Studio or VS Code adds an editor, debugger, and templates — optional but helpful.
Why should you care?
Without the SDK, dotnet new mvc will not work. A good editor saves hours when stepping through controllers line by line.
See it live — copy this example
Create an MVC project (dotnet new mvc), add the code, and run dotnet run.
# Install SDK from https://dotnet.microsoft.com/download (LTS)
dotnet --version
# Create and run first project
dotnet new mvc -n ShopNest.Mvc
cd ShopNest.Mvc
dotnet runRun Example »
This lesson uses terminal or setup steps. Run commands on your computer — the live editor appears on coding lessons.
What happened?
- dotnet --version should show 8.x or 9.x LTS.
- dotnet new lists templates including mvc.
- dotnet run compiles and starts Kestrel with a localhost URL.
Try it yourself
- Download and install .NET SDK LTS.
- Open terminal, run dotnet --version.
- Install VS Code + C# Dev Kit OR Visual Studio Community.
- Change text or labels in the example and run again — watch the browser update.
- Break the code on purpose (remove a semicolon), read the error message, then fix it.
Remember
SDK is required; IDE is strongly recommended. dotnet CLI creates and runs projects. LTS versions are safest for learning and production.
