.NET Data Community Standup: Teach your AI agent database design with T-SQL static code analysis
Erik will show two ways you can take advantage of the open-source set of T-SQL static analysis rules, and the surrounding set of tools, that he maintains. First, you can get live code analysis of your SQL scripts as you type them in VS Code, Visual Studio and SQL Server Management Studio. Secondly, in companionship with EF Core Power Tools, you can build your database model (and EF Core model) with AI and guide it by enforcing the more than 140 rules in the package. 🎙️ Featuring: Jiri Cincura, Erik Ejlskov Jensen #net #data #efcore #tsql #vs #vscode #ssms
