Please help!

Hello, I am new to unity so I am a bit confused. I will be extremely glad if someone helps me with the problem I have. When I start to write my code in visual studio there are not any key worlds that appear when u start to write your code and also in the solution explorer there is a message: Assembly-CSharp.csproj:The application is not installed. I tried to switch to lower version of the Visual Studio Code Editor package to 1.1.3 and also I installed the nesesary Game development for Unity from the visual studio installer. I also have this problem and can not find what I miss. Please tell me if you have any idea, thank u in advance!
