I deleted Visual Studio, but i love c#. I download dotnet from dotnet official site and installed it. Then i writen in command line dotnet new console
and all work, dotnet run
work. Then i make other folder and there writen dotnet new classlib
(is .dll) and it work. But i don't know how to add my .dll file into my project. How to do it?
You either edit the XML of the .csproj file manually, or do it on the command line:
dotnet add app/app.csproj reference lib/lib.csproj
This adds the XML for you:
<ItemGroup>
<ProjectReference Include="..\lib\lib.csproj" />
</ItemGroup>
