Azure DevOps pipelines have a pretty handy feature called Pipeline Caching. It’ll help you avoid annoyingly long NuGet package restores in your builds. And that makes sense – why would you restore packages again and again and again, if you’re not updating your dependencies meanwhile? And especially in the case of CI or CD pipeline, you’ll end up having a pipeline running constantly without packages actually getting bumped up – so your NuGet task is downloading the same packages over and over again. That’s where…Continue reading Azure DevOps Pipelines Caching
Recently, I ran into a problem that I definitely caused myself. I had a certificate, that was created to authenticate an app against Azure AD. The encryption key for the .pfx file was, however, lost. I could just create a new certificate, configure the app service to use that, and replace the old certificate… But that’s manual labor and where’s the fun in that? I prefer a solution that included a bit more coding! After a bit of googling, I found a nice, programmatic solution…Continue reading How to recover the private key of a (.pfx) certificate?
Well, that title is a mouthful. But it’s the topic for today, so what can you do? That said, this article should be pretty topical, as the issue started popping up only a few days ago. Chances are it’ll be patched soon enough, but in the meantime, it’s always useful to document the fix! Problem When running or debugging Azure Functions locally, your runtime just blurts our this error and fails to compile your functions: [2021-01-11T10:28:11.495Z] A host error has occurred during startup operation ‘0d00defa-b8bd-4fb8-9794-b0e5950a4c38’.…Continue reading How to fix “System.IO.FileSystem: Could not find a part of the path \AppData\Local\AzureFunctionsTools\Releases\3.17.0\workers. Value cannot be null. (Parameter ‘provider’)” when running Azure Functions locally?
This article explains one easy workaround to a lot of Visual Studio authentication issues. Personally, it’s helped me multiple times when Cloud Explorer has gotten into a weird authentication loop or Visual Studio stops seeing my MSDN subscription. And it also helps you clean up any old and unused credentials – such as the ones you only used once in 2018 to log into a customer’s Azure environment to debug an issue they had with their AppInsights extension on an app service (and that ended…Continue reading How to nuke the Identity Cache in Visual Studio?
This was a fun one! Suddenly, while running or debugging my ASP.NET Core 3.1 application, I started getting errors about missing assemblies, along the lines of “FileNotFoundException: Could not load file or assembly Microsoft.AspNetCore.Components.Forms”. These DLL files were not required a minute earlier – nor did requiring them really make much sense in my mind – but there was a nonsensical, easy fix, so in the end, it was all good! But let’s go through this thing in order. What was the problem? Problem So,…Continue reading Fixing unexpected Microsoft.AspNetCore package errors after a dependency update
