Your startup project 'Dewiride.Inventory.Data' doesn't reference Microsoft.EntityFrameworkCore.Design. This package is required for the Entity Framework Core Tools to work. Ensure your startup project is correct, install the package, and try again. The message offers two fixes, in one sentence. In a solution where the DbContext lives in a class library, the first one is usually right: the tools were using the wrong startup project.

No project was found. Change the current working directory or use the --project option. This is often the first thing dotnet ef prints in a solution with more than one project. It doesn't even build: the folder you're in has no project file for it to use. Here's why, how to see which projects you have, and the command that works.

After I edited a project's global.json, every dotnet command in the folder stopped working with "A compatible .NET SDK was not found", even though a newer .NET 10 SDK was installed. The message itself names the file that caused it. The fix was one word in global.json: the rollForward value decides whether a newer SDK may stand in for the requested one.

I printed a line of equals signs in zsh, the default shell on macOS, and got zsh: ===== not found instead. The same thing happens to [ "$a" == 1 ], as zsh: = not found. zsh reads a word that starts with = as the name of a command; quote the word, and the line prints.

A real .NET C# Web API usually isn't one project. It's a solution: the API itself, plus one or more class libraries for code that doesn't belong in the web layer, such as the database code. This guide builds that structure from the command line with .NET 10, adds the settings that production projects use, and fixes the two errors those settings raise on the template's own code.

Before you follow a guide, report a bug or plan an upgrade, you need to know exactly which MySQL you're talking to. MySQL tells you in several places, and one of them works without signing in at all. This guide shows five ways, with real output from MySQL 9.7.4 in Docker, and the one place where the version you see can mislead you.

The official MySQL Docker image already contains the mysql command-line client, so you don't need to install anything on your computer to run SQL. One docker compose exec command opens the client inside the running container. This guide signs in, runs the first few queries every new database deserves, and shows the small things that confuse beginners.

The passwords people make up are easy to guess. The ones a computer picks at random aren't. One command in your terminal generates a long, cryptographically random password made only of letters and digits, which is safe to paste into connection strings, .env files and YAML. This guide shows it for macOS, Linux and Windows.

A .NET C# project fills up with files that should never be committed: build output in bin and obj, editor settings, and secrets such as .env. The .NET SDK ships a ready-made .gitignore that covers all of them, and one command adds it to your project. This guide adds it, shows what it ignores, and proves a file is really ignored.

Git keeps a history of every change you make to a project, so you can see what changed, when, and go back if something breaks. Three commands turn any folder into a Git repository with its first saved snapshot: git init, git add and git commit. This guide runs them on a real project and shows every line of output.
