Solution and Projects in dotnet

  • Project is a C# application. It is defined by a .csproj file
  • Solution is a collection of multiple projects. It is defined using a .sln file
  • A simple C# solution folder structure can be as follows
ConsoleAppSolution
│   ConsoleAppSolution.sln
│
├───ConsoleApp1
│       ConsoleApp1.csproj
│       Program.cs
│
└───ConsoleApp2
        ConsoleApp2.csproj
        Program.cs

Development with dotnet CLI

  • dotnet CLI (command line interface) is a part of dotnet SDK. It can be used to run dotnet commands
  • A solution in dotnet (defined by .sln file) is a group of dotnet projects (defined by .csproj file)
  • Create a new dotnet solution named “CSharpApps” using dotnet new sln -n CSharpApps
  • Create a new dotnet console project named “HelloWorld” in a sub folder using dotnet new console -o HelloWorld
  • Add the project to solution using dotnet sln add HelloWorld
  • A folder structure like the following should be created
C:.
│   CSharpApps.sln
│
└───HelloWorld
        HelloWorld.csproj
        Program.cs
  • Run the project using dotnet run --project HelloWorld

Development with VS code

  • Open a folder in VS code
  • Open command palette (Ctrl+Shift+P) and search “.NET New Project”

  • Select the project type as Console App

image.png

  • Enter the project name and proceed

For example using System; statement is not required to run the dotnet console application as shown below Console . WriteLine ( "Hello World!" ) ; Additional implicit usings can be declared in a C# project with global usings statements in any one of the project’s C# files as shown below. global using Ardalis . GuardClauses ; global using MediatR ; global using Project2 . Utils ; Existing implicit usings can be removed or included in the .csproj file of the C# project as shown below < ItemGroup > < Using Remove = " System.Threading.Tasks " /> < Using Include = " System.Math " /> </ ItemGroup > The implicit usings added in a C# project is based on the project type as sh
