Okay, let’s drop the third person speech. You can read more about me and stuff I do from here: https://www.koskila.net/antti-koskela/
In addition to this being my personal home page (nowadays, I guess that means a catalogue and links to my other stuff online in different channels, right?), I’m blogging about all kinds of exciting and/or tricky topics.
See a few of my latest blog articles below:
- Azure Function build fails with “Mono.Cecil.AssemblyResolutionException: Failed to resolve assembly: Microsoft.AspNetCore.Mvc.Core”Another fun one with Azure Functions! At least it’s a simple one: this time, I ran into a weird issue while doing some code reusing – well, copy-pasting – between a couple of different projects. I was lovingly hand-crafting some Azure Functions, while suddenly the Azure Functions host would throw me this in ugly, red letters: Mono.Cecil.AssemblyResolutionException: Failed to resolve assembly: ‘Microsoft.AspNetCore.Mvc.Core, Version=184.108.40.206, Culture=neutral, PublicKeyToken=adb9793829ddae60’ at Mono.Cecil.BaseAssemblyResolver.Resolve(AssemblyNameReference name, ReaderParameters parameters) at Mono.Cecil.BaseAssemblyResolver.Resolve(AssemblyNameReference name) at Mono.Cecil.DefaultAssemblyResolver.Resolve(AssemblyNameReference name) at Mono.Cecil.MetadataResolver.Resolve(TypeReference type) at Mono.Cecil.ModuleDefinition.Resolve(TypeReference type) at Mono.Cecil.TypeReference.Resolve() at…Continue reading Azure Function build fails with “Mono.Cecil.AssemblyResolutionException: Failed to resolve assembly: Microsoft.AspNetCore.Mvc.Core”
- How to update from deprecated Microsoft.Azure.Services.AppAuthentication to new and shiny Azure.Security.KeyVaults.Secrets?So, a while ago I posted about a fairly simple way to write your code for fetching secrets (and other confidential stuff) from Azure Key Vault in such a way, that it would work the same way both in Azure and on your local dev box. I find this pretty important, as it reduces the need for weird workarounds and fallbacks in your code, and at the same time enables you to harness the Azure Key Vault for that sweet spot of “good enough security…Continue reading How to update from deprecated Microsoft.Azure.Services.AppAuthentication to new and shiny Azure.Security.KeyVaults.Secrets?
- Fixing Blazor WebAssembly .NET 6 MSAL authorization bugLet’s make this short and sweet. In this particular case, upgrading a Blazor WASM solution to .NET 6 broke the authentication when deployed to Azure. The same issue could probably happen to a fresh project, though. This is what you’re running into: If you open your browser console, you’ll see 2 interesting errors – first: dotnet.6.0.0.o2we6pverp.js:1 mono_wasm_runtime_ready login.microsoftonline.com/common/oauth2/v2.0/token:1 Failed to load resource: the server responded with a status of 400 (Bad Request) And a moment later, an error along the lines of: blazor.webassembly.js:1 crit: Microsoft.AspNetCore.Components.WebAssembly.Rendering.WebAssemblyRenderer…Continue reading Fixing Blazor WebAssembly .NET 6 MSAL authorization bug
What’s koskila.net about?
The tagline for my blogging efforts has been Solutions are worthless unless shared for quite a while already. That’s to say, since I’ve gotten a lot of help from the community whenever I’ve had issues getting something to work, I like to give something back. This blog is my way of doing that.
Blogging has been a great, lightweight way to sort my thoughts and document weird fixes and findings along the way. And boy, has there been a lot of them! Microsoft’s stack always keeps surprising me – mostly in a positive way, but there’s an occasional bump along the way too.
A lot of people seem to struggle with the same issues, as the blog nowadays has over 70 000 visitors monthly. May you find my thoughtful workarounds as useful as I have!
In addition to more technical posts, sometimes I might post about my sessions at different community events, or experiences as an expat living in a foreign country (in 2017, that country was the USA, in 2018 & 2019 Canada). Right before the pandemic, I moved back to Finland to live in the middle of a forest.
Back in the olden days, when the world was not on fire, I used to travel to different events. Now it’s all digital, which is… Not quite the same.
You can also see a list of all my sessions and session materials.
No upcoming engagements. I’ve cut down traveling due to the pandemic.
