This feature brings AI-driven modernization tooling directly into **Visual Studio**, enabling enterprises to accelerate and automate the migration of legacy .NET applications to **Microsoft Azure**. **What It Does** The new Copilot capability analyzes existing application codebases to identify modernization opportunities, recommend **Azure-native services**, and apply **best-practice code transformations**. It then validates successful builds and test results—all with **human-in-the-loop approval** to maintain control and code quality. Teams can use predefined migration scenarios to move from **on-premises SQL, file storage, and identity systems** to fully managed Azure resources. The result is a significant reduction in both migration time and risk. Learn more in GitHub’s announcement: [GitHub Copilot App Modernization for .NET Enters Public Preview](https://github.blog/changelog/2025-07-21-github-copilot-app-modernization-for-net-enters-public-preview/) --- **Why This Matters** **Cloud Modernization Becomes a Predictable, Guided Experience** Copilot evaluates code, recommends modernization paths, and automatically remediates common issues—allowing teams to **modernize legacy workloads in days or weeks, not years**. **AI-Driven with Human Oversight** By combining **automation with human-in-the-loop validation**, Copilot accelerates migration tasks such as transitioning to **managed identities**, **Azure Blob/File Storage**, and **Entra ID**, while preserving developer control and ensuring safe code changes. **Built for Complex, Enterprise-Scale Scenarios** The tool supports a variety of predefined modernization patterns—covering database migrations, credential hardening, and message queue conversions—reducing manual effort and aligning to **Microsoft best practices**. **Deep Integration with Azure Ecosystem** Copilot’s modernization tools integrate with **Azure Migrate**, **AppCAT**, and **Migration and Modernization Program (MCP)** services to improve accuracy in planning, execution, and post-migration validation. This alignment helps IT leaders and architects maintain visibility, control costs, and ensure modernization success. --- **Final Thoughts** For organizations running legacy .NET workloads, **GitHub Copilot’s app modernization capabilities** mark a major step forward. By bringing AI-driven guidance, automation, and integrated validation into Visual Studio, Microsoft is making **cloud transformation faster, safer, and more predictable** than ever before. 1 min read #### [Copilot Announced for Power Platform](https://www.serverless-solutions.com/blog/copilot-announced-for-power-platform) [Admin](https://www.serverless-solutions.com/blog/author/admin) : Jan 7, 2026 12:15:54 PM The Large Language Models (LLM) capabilities powering GPT are coming to the Power Platform.
