Creating a class library in visual studio code

Question

It might be a silly question, Let's say I don't have a Windows OS, have a Linux. I have created a .Net core console app, also want to create a class library and reference it in console app. I can't find if i am able to do it also couldn't find a sample on Microsoft .Net core page. Is there an extension in vs code? Or isn't it possible with it? If i am mistaken could you please guide me?

The best way to do it is from the console, since you are using the latest supported templates this way. VSCode also has an integrated terminal you can use for this.

$ dotnet new lib -o MyLib
$ dotnet new sln #assuming there is no .sln file yet. if there is, skip this
$ dotnet sln add MyLib/MyLib.csproj
$ cd MyConsoleApp
$ dotnet add reference ../MyLib/MyLib.csproj

If you need different frameworks, you can use the -f argument:

$ dotnet new lib -o MyLib -f netcoreapp2.0

or manually change the <TargetFramework> element inside the generated .csproj file.

I found that in Visual Studio Code v1.39.2 you have to use dotnet new classlib -o MyLib – Condensation

There is a very useful VSCode extension called .NET Core Add Reference, it gives a GUI – Ozone

Is it possible to add a new or existing cs file to a csproj? This seems to assume that all projects have one-and-only-one cs file. – Fifi

The SDK-style projects automatically include very *.cs file in the directory hierarchy so no need to add them (unlike classic csproj for .net framework) – Theaterintheround
