NAME
       dotnet-sln - Lists or modifies the projects in a .NET solution file.

SYNOPSIS
              dotnet sln [<SOLUTION_FILE>] [command]

              dotnet sln [command] -h|--help

DESCRIPTION
       The dotnet sln command provides a convenient way to list and modify projects in a solution file.

   Create a solution file
       To  use the dotnet sln command, the solution file must already exist.  If you need to create one, use the dotnet new command
       with the sln template name.

       The following example creates a .sln file in the current folder, with the same name as the folder:

              dotnet new sln

       The following example creates a .sln file in the current folder, with the specified file name:

              dotnet new sln --name MySolution

       The following example creates a .sln file in the specified folder, with the same name as the folder:

              dotnet new sln --output MySolution

ARGUMENTS
       • SOLUTION_FILE

         The solution file to use.  If this argument is omitted, the command searches the current directory for one.  If  it  finds
         no solution file or multiple solution files, the command fails.

OPTIONS
       • -?|-h|--help

         Prints out a description of how to use the command.

   Commands
   list
       Lists all projects in a solution file.

SYNOPSIS
              dotnet sln list [-h|--help]

ARGUMENTS
       • SOLUTION_FILE

         The  solution  file to use.  If this argument is omitted, the command searches the current directory for one.  If it finds
         no solution file or multiple solution files, the command fails.

OPTIONS
       • -?|-h|--help

         Prints out a description of how to use the command.

   add
       Adds one or more projects to the solution file.

SYNOPSIS
              dotnet sln [<SOLUTION_FILE>] add [--in-root] [-s|--solution-folder <PATH>] <PROJECT_PATH> [<PROJECT_PATH>...]
              dotnet sln add [-h|--help]

ARGUMENTS
       • SOLUTION_FILE

         The solution file to use.  If it is unspecified, the command searches the current directory for one and fails if there are
         multiple solution files.

       • PROJECT_PATH

         The   path   to   the   project   or   projects   to   add   to   the   solution.    Unix/Linux   shell  globbing  pattern
         (https://en.wikipedia.org/wiki/Glob_(programming)) expansions are processed correctly by the dotnet sln command.

         If PROJECT_PATH includes folders that contain the project folder, that portion of the path  is  used  to  create  solution
         folders.  For example, the following commands create a solution with myapp in solution folder folder1/folder2:

                dotnet new sln
                dotnet new console --output folder1/folder2/myapp
                dotnet sln add folder1/folder2/myapp

         You can override this default behavior by using the --in-root or the -s|--solution-folder <PATH> option.

OPTIONS
       • -?|-h|--help

         Prints out a description of how to use the command.

       • --in-root

         Places  the  projects  in the root of the solution, rather than creating a solution folder.  Can’t be used with -s|--solu‐
         tion-folder.

       • -s|--solution-folder <PATH>

         The destination solution folder path to add the projects to.  Can’t be used with --in-root.

   remove
       Removes a project or multiple projects from the solution file.

SYNOPSIS
              dotnet sln [<SOLUTION_FILE>] remove <PROJECT_PATH> [<PROJECT_PATH>...]
              dotnet sln [<SOLUTION_FILE>] remove [-h|--help]

ARGUMENTS
       • SOLUTION_FILE

         The solution file to use.  If it is unspecified, the command searches the current directory for one and fails if there are
         multiple solution files.

       • PROJECT_PATH

         The   path   to   the   project   or   projects   to   remove  from  the  solution.   Unix/Linux  shell  globbing  pattern
         (https://en.wikipedia.org/wiki/Glob_(programming)) expansions are processed correctly by the dotnet sln command.

OPTIONS
       • -?|-h|--help

         Prints out a description of how to use the command.

EXAMPLES
       • List the projects in a solution:

                dotnet sln todo.sln list

       • Add a C# project to a solution:

                dotnet sln add todo-app/todo-app.csproj

       • Remove a C# project from a solution:

                dotnet sln remove todo-app/todo-app.csproj

       • Add multiple C# projects to the root of a solution:

                dotnet sln todo.sln add todo-app/todo-app.csproj back-end/back-end.csproj --in-root

       • Add multiple C# projects to a solution:

                dotnet sln todo.sln add todo-app/todo-app.csproj back-end/back-end.csproj

       • Remove multiple C# projects from a solution:

                dotnet sln todo.sln remove todo-app/todo-app.csproj back-end/back-end.csproj

       • Add multiple C# projects to a solution using a globbing pattern (Unix/Linux only):

                dotnet sln todo.sln add **/*.csproj

       • Add multiple C# projects to a solution using a globbing pattern (Windows PowerShell only):

                dotnet sln todo.sln add (ls -r **/*.csproj)

       • Remove multiple C# projects from a solution using a globbing pattern (Unix/Linux only):

                dotnet sln todo.sln remove **/*.csproj

       • Remove multiple C# projects from a solution using a globbing pattern (Windows PowerShell only):

                dotnet sln todo.sln remove (ls -r **/*.csproj)

       • Create a solution, a console app, and two class libraries.  Add the projects to the solution, and use the --solution-fold‐
         er option of dotnet sln to organize the class libraries into a solution folder.

                dotnet new sln -n mysolution
                dotnet new console -o myapp
                dotnet new classlib -o mylib1
                dotnet new classlib -o mylib2
                dotnet sln mysolution.sln add myapp\myapp.csproj
                dotnet sln mysolution.sln add mylib1\mylib1.csproj --solution-folder mylibs
                dotnet sln mysolution.sln add mylib2\mylib2.csproj --solution-folder mylibs
