What dependencies do I need to compile PowerShell on Windows?▼

Compiling PowerShell on Windows requires Visual Studio 2019+, the .NET Core SDK, and Git. You can manage and setup these build dependencies automatically by running the Start-PSBootstrap command with the Dotnet scenario.

How do I run Pester tests after building PowerShell Core?▼

Run Pester tests for PowerShell Core by executing the Start-PSPester command with the -UseNuGetOrg parameter. This validates your local build and verifies code changes within the PowerShell repository.

What is the best way to bootstrap dependencies for a PowerShell repository?▼

The best way to bootstrap dependencies for the PowerShell repository is using Start-PSBootstrap -Scenario Dotnet. This prepares the Windows development environment by installing required .NET frameworks and tools before compilation.

Can I restore PowerShell modules while compiling the core?▼

Yes, you can restore PowerShell modules during the build process by running Start-PSBuild with the -PSModuleRestore and -UseNuGetOrg parameters. This ensures all required modules are available for testing.
