Aspire, Functions, and JSON performance
A varied .NET roundup with Aspire and Azure Functions integration, JSON serialization comparisons, hybrid search in Azure SQL, and more.
Jasen's top three picks
- 1 Better Together: .NET Aspire, Azure Functions, and Visual Studio
devblogs.microsoft.com
A practical preview showing how Aspire, Azure Functions, and Visual Studio fit together in real workflows.
- 2 Optimizing JSON Serialization in .NET: Newtonsoft.Json vs. System.Text.Json
blog.elmah.io
A useful comparison that goes beyond syntax and looks at JSON serialization tradeoffs and performance.
- 3 Create Foreign Keys Dynamically in SQL Server Database
c-sharpcorner.com
Dynamic foreign key creation is niche, but it’s exactly the kind of SQL Server script people end up needing.
Editor's note
I curated a fairly mixed issue this time, with infrastructure, data, language, and tooling pieces side by side. The Aspire and Azure Functions preview is one of the more practical platform updates, and the Azure SQL hybrid search post should be useful for anyone building modern discovery features. I also liked the EF Core testing standup and the GitHub Copilot MCP write-up for their hands-on, real-world angle.
