These samples are setup to guide C++ programmers into C# beginning with the classic "Hello World!" and then introducing additional concepts one at a time.
These samples will include some language features as new as C# 10. You should have (minimum) Visual Studio 2022 installed on your system supporting .NET 7.0.
It is assumed that the reader has some experience with programming languages and, more specifically, experience with C++. Several concepts that are already present in a language like C++ won't be explained here and you need to be familiar with them. Some of those concepts are (but are not limited to):
- Basic programming constructs (variables, arrays, loops, io).
- Class types (class and struct)
- Class vs instance members (static)
- Basic access (public, private, protected)
- Namespaces
All of the details are in the code. Go through the numbered samples one at a time opening the solution file in Visual Studio or opening the folder in Visual Studio Code. Then read through the comments in the source file(s) thoroughly.
Each folder contains a solution file and a project file. Open the solution file in Visual Studio (2022 or later), build, and then run. Note that these are all console apps. That means that if you run any of the apps from within Visual Studio, the console could disappear before you have a chance to see anything.
By default, Visual Studio 2022 pauses at the end of a console application and prompts the user to hit any key to close the console. If you're not seeing this, you need to open up your options dialog Tools|Options, go to the General section under Debugging, and make sure that the option Automatically close the console when debugging stops is NOT selected.
You can build/run these samples in Visual Studio Code. Simply open the desired folder in Code. The first time you do so, you'll likely see a prompt stating Required assets to build and debug are missing. Add them?. Select Yes and note that Code creates a folder named .vscode in your project folder. To run the same, do the following:
- Select Terminal|New Terminal from the menu or type Ctrl+Shift+'.
- In the new terminal, type dotnet run. At that point the sample should run and you should see the results.
You can run clean.cmd from the top level folder to loop through all of the sample folders and clean up build artifacts/outputs/etc.
