D365 Solution Comparer is a custom XrmToolBox plugin for Microsoft Dynamics 365 and Dataverse. It helps compare solutions between a source environment and a target environment so teams can quickly spot differences before deployments, validation, or troubleshooting.

This tool was built to simplify solution comparison across environments by providing a clear side by side view of key solution metadata.

It compares:

• Solution Unique Name
• Display Name
• Version
• Publisher
• Package Type based on managed or unmanaged state

The plugin is designed for internal ALM checks, release validation, support reviews, and general environment comparison work.

• Connect to a target environment
• Load target environment solutions
• Compare source and target solutions
• Highlight differences by status
• Multi-select result filtering

The tool can identify and display these statuses:
