TLDR: GitHub Copilot has officially launched its app modernization features for Java and .NET developers, leveraging AI to drastically cut down the time required for application upgrades, migrations, and cloud deployments from months to mere days. This suite of tools offers automated assessments, code transformations, dependency updates, and containerization capabilities.
Microsoft has announced the general availability of GitHub Copilot’s advanced app modernization features for both Java and .NET development environments, a move poised to revolutionize how organizations approach legacy system upgrades and cloud migrations. This new offering, powered by artificial intelligence, promises to condense modernization timelines from several months to just a few days, significantly boosting developer productivity and efficiency.
The core of this new capability lies in its comprehensive suite of AI-driven tools. Developers can now benefit from automated application assessment reports, which provide crucial insights into existing codebases, configurations, and dependencies. Following the assessment, Copilot facilitates automated code transformations, ensuring compatibility with newer versions and modern architectural patterns. It also handles critical tasks such as build patching and dependency updates, which are often time-consuming and error-prone when performed manually. Furthermore, the service includes robust containerization capabilities, streamlining the deployment of modernized applications to cloud platforms like Azure.
According to Microsoft, these features are designed to ‘offload critical yet time-consuming tasks, like version upgrades, to AI agents, reducing weeks of work to days and allowing more time for building, not maintaining.’ This directly addresses the significant challenges developers face across the entire software lifecycle, particularly in maintaining and upgrading older applications. The AI agent guides users through assessment, solution recommendations, code fixes, and validation, all within their integrated development environment.
For Java projects, the modernization capabilities are accessible within Visual Studio Code and require a GitHub Copilot Pro, GitHub Copilot Pro+, GitHub Copilot Business, or GitHub Copilot Enterprise subscription plan. It supports Git-based Maven or Gradle Java projects. For .NET applications, the features are integrated into Visual Studio 2022 (version 17.14.16 or later, including Enterprise, Professional, or Community editions) and also necessitate a compatible Copilot subscription.
