![]() The default local store path is set as a directory under %ProgramData% Move-Moves the local store to the path that you specify. If you specify the /sourceURI argument, all books are removed, and the /booklist argument is ignored. This switch requires the /booklist argument or the /sourceURI argument. Uninstall-Removes the books that you specify from the local content store. If you don't specify the /booklist argument, all books on the /sourceUri are installed. If you don't specify the /sourceURI argument, the default Visual Studio URI is used as the installation source. This switch requires the /booklist argument, the /sourceURI argument, or both. Install-Adds books from the specified installation source to the local content store. The following table defines the switches and arguments that you can use for the command-line tool for Help Content Manager: Switch This might be unexpected, but this is because the same Help Viewer is used for both Visual Studio versions. The command produces this output: The factorial of 3 is 6.The catalog name is VisualStudio15 for both Visual Studio 2017 and Visual Studio 2019. If your application has no compilation errors, an executable file that's named Factorial.exe is created.Įnter the following command to calculate the factorial of 3: output reads: The factorial of 3 is 6.įrom the Start screen or Start menu, open a Visual Studio Developer Command Prompt window, and then navigate to the folder that contains the file that you created.Įnter the following command to compile the application. The following list shows valid Main signatures: public static void Main(). ![]() Unlike C and C++, the name of the program is not treated as the first command-line argument in the args array, but it is the first element of the GetCommandLineArgs() method. Parameters are read as zero-indexed command-line arguments. When using Visual Studio to create Windows applications, you can add the parameter manually or else use the GetCommandLineArgs() method to obtain the command-line arguments. The Main method can be declared with or without a string parameter that contains command-line arguments.This specifically excludes an async void Main method. If and only if Main returns a Task or Task, the declaration of Main may include the async modifier.Main can either have a void, int, Task, or Task return type.(In the earlier example, it receives the default access of private.) The enclosing class or struct is not required to be static. Main must be static and it need not be public. Main is declared inside a class or struct.The Main method is the entry point of an executable program it is where the program control starts and ends.Starting in C# 9, you can omit the Main method, and write C# statements as if they were in the Main method, as in the following example:įor information about how to write application code with an implicit entry point method, see Top-level statements. Display the number of command line arguments. For more information, see StartupObject (C# Compiler Options). If you have more than one class that has a Main method, you must compile your program with the StartupObject compiler option to specify which Main method to use as the entry point. There can only be one entry point in a C# program. (Libraries and services do not require a Main method as an entry point.) When the application is started, the Main method is the first method that is invoked. The Main method is the entry point of a C# application.
