Upgrading your .NET applications isn’t just about getting the solution to compile successfully. In this episode of The Tech Vault with Mitchel Sellers, we take a deep dive into what a real .NET upgrade process should include to ensure your applications are modern, secure, maintainable, and taking advantage of the latest platform improvements. Too often, teams update package versions, fix a few breaking changes, and stop once the build turns green. But that approach can leave performance gains, security improvements, tooling updates, framework enhancements, and modernization opportunities completely untouched. In this episode, we cover: ✅ Evaluating framework and dependency compatibility ✅ Identifying hidden upgrade risks and breaking behaviors ✅ Updating libraries, SDKs, workloads, and tooling ✅ Reviewing authentication, hosting, and configuration changes ✅ Taking advantage of new .NET runtime and ASP.NET Core features ✅ Modernizing legacy patterns during upgrade cycles ✅ Testing, validation, and deployment considerations ✅ Why “it builds” is only the beginning Whether you are making a small .NET 9 to .NET 10 upgrade, or a larger transition, the tips here should help! 🔗 Learn more at: https://mitchelsellers.com https://iowacomputergurus.com 🎥 Subscribe for more .NET, Azure, Blazor, MAUI, architecture, and development insights from The Tech Vault with Mitchel Sellers. #dotnet #aspnetcore #blazor #softwaredevelopment #azure #dotnetupgrade #visualstudio #csharp

I'm a huge fan of Entity Framework Migrations, using them for almost all client projects. In a given week, I will see dozens of changes deploy to production successfully across our portfolio of projects. However, there is always that "one task" that results in a failure and each time it happens it triggers an update to our internal training and review processes, and it has to do with repeatable scripting and the use of the "idempotent" flag. I thought I'd share our experiences with everyone, to help prevent issues for others.

With the recent preview release of GitHub CoPilot Agents, the importance of proper instructions for the agents is as important as it ever has been. But how do I effectively manage this when we have limits on the prompting depth and what items it has access to?
