When building apps that connect to APIs, we typically focus on getting the app to work. But what happens when the API is slow, returns errors, or becomes unavailable? The last thing you want is an angry customer calling you when your app breaks. But it’s hard to simulate how your app will handle these scenarios when you don’t control the APIs you integrate with. Unless you use Dev Proxy. The hard thing about connecting to APIs These days, it’s hard to imagine an app that’s not connected to an API. We use APIs for everything: from getting data to performing actions. But there’s more to using an ..read more

NET 8 is a big step forward for building and using containers, with improvements for performance, security, and usability. We’ve been working over several releases to make .NET one of the simplest and most secure container platforms, as a default experience. Those efforts have all come together in an integrated way with .NET 8. We’ve delivered on the most common requests: non-root images, smaller image size, and built-in image publishing. We’ve also delivered some critical features that are required for advanced workflows. We’ve pivoted to dotnet publish as our recommended approach to contain ..read more

We are happy to announce that we just published an early preview of support for testing Native AOT with MSTest, and we welcome all of you to try it. This new solution is powered by a completely new testing engine that we wrote from ground up, to allow running tests in Native AOT, and that works together with the existing MSTest runner (Microsoft.Testing.Platform). We also leveraged the power of source generators, to discover tests during compilation, which solved one of the big hurdles that prevented us from compiling and running tests in Native AOT. What is Native AOT .NET applications can be ..read more

It has been over a year since I last updated everyone on the status of .NET in the Bing stack, specifically the high-performance workflow execution engine sitting right in the middle of everything. In that time, the scope of this engine has only increased, especially with the release of Microsoft Copilot. While our workflow engine originated under Bing, it’s fair to say that it now undergirds a significant portion of the search and data stack in many Microsoft applications. We started testing .NET 8 from its early preview releases. While there were clear incremental benefits in performance acr ..read more

Apple is introducing a privacy policy for including privacy manifest files in new and updated applications targeted for iOS, iPadOS, and tvOS platforms on the App Store. Note that macOS apps are excluded at least for the time being. The privacy manifest file (PrivacyInfo.xcprivacy) lists the types of data your .NET MAUI applications, or any third-party SDKs and packages collect, and the reasons for using certain Required Reason APIs categories. At the time of writing Apple is already sending out notices about including this policy in your apps. As of May 1, 2024, this will be mandatory in orde ..read more

Often sample projects starts with a few “magic strings”, those variables contains URLs and key information related to a deployment or external resources that we will have to change to use the sample. As an example in .NET it could look like this: string openAIEndpoint = "https://"; string openAIDeploymentName = "my-ai-model"; string openAiKey = "123456abcd789EFGH"; // ... This post shows how you to automatically generate .NET secrets from the Azure deployment and how your .NET app can read them. Users who would like to try your sample won’t have to edit anything anymore! They will only have ..read more
