Announcing Crescendo 0.9.0 Release Candidate (RC)

We are pleased to announce the Release Candidate (RC) of PowerShell Crescendo, a framework to rapidly develop PowerShell cmdlets for native commands, regardless of platform.

The release candidate is now available for download on the PowerShell Gallery.

To install Microsoft.PowerShell.Crescendo:

Install-Module Microsoft.PowerShell.Crescendo -AllowPrerelease

Crescendo Release Candidate Updates

Crescendo 0.9.0 Release Candidate adds support for a versioned schema and fixes scenarios suggested by the community.

• Added versioned schema to support future updates. Issue #112
• Fixed quoting empty string parameter values. Issue #100
• Fixed showing OriginalCommand in help example unless specified. Issue #57

Schema versioning

With this release of Crescendo, the JSON schema for the configuration is now versioned. While we don’t expect there to be any changes, supporting a versioned schema makes is easier to support changes in future releases.

The URL for the current version of the schema is: https://aka.ms/PowerShell/Crescendo/Schemas/2021-11.

Support for empty string parameter values

Crescendo now supports parameters that accept empty strings as argument values. The proxy cmdlet created by Crescendo now recognizes an empty string provided as parameter value and ensures that the empty string is passed as "" to the native executable.

For a more detailed example use case, see Issue #100.

Displaying OriginalCommand in Help

The OriginalCommand property of a cmdlet definition is intended to contain the original native command and parameters invoked by the proxy cmdlet. This information is display by Get-Help. With this release, if the OriginalCommand property is empty, no placeholder is written to the comment-based help when the module is exported.

Future plans

The plans for the general availability (GA) release will be based on community feedback. Our goal is to make it easier to convert your native commands to PowerShell cmdlets and receive the benefits that PowerShell provides.

We value your ideas and feedback and hope you will give Crescendo a try. Stop by our GitHub repository and let us know of any issues you find or features you would like added.
