When you have to store sensitive data, you can use #dotnet #csharp Data Protection API to encrypt them. It's helpful, and you get a lot of features out of the box like key management key rotation, and various options for storing keys. #code #programmer

#Azure Load Testing - comparing test runs improved. Thanks, @nicktrog! x.com/ppenza/status/16168001…

Asking for a short description(legend) when comparing test results in #Azure Load Testing - and yes, you can't see which test run represents a particular graph...maybe because the results are very similar ..

Using the #Azure Load Testing service you can trigger load/stress tests during CI/CD process. Checkout my simple configuration for #csharp minimal API - github.com/rh8512/azure-gith… Steps: build c# minimal API, deploy, and run load tests... #loadtesting #dotnet #CodeNewbie

#Azure Load Testing looks promising. It’s in preview. Apache JMeter is used for running load tests. What’s nice: integration with Azure Monitor, tests can be triggered by GitHub actions. Now we have additional tool for performing load and stress test for our apps. #loadtesting
