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 topics!
See a few of my latest blog articles below:
- 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?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.

- How to nuke the Identity Cache in Visual Studio?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?
- Fixing unexpected Microsoft.AspNetCore package errors after a dependency updateThis was a fun one! Suddenly, while running or debugging my ASP.NET Core 3.1 application, I started getting errors about missing assemblies. 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 now? Problem So, this was the error I was running into, whenever I ran…Continue reading Fixing unexpected Microsoft.AspNetCore package errors after a dependency update
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!
These are some of the topics I often write about: Azure Active Directory errors, Azure PowerShell errors, terrifying examples about how to open a modal dialog in SharePoint using JavaScript, all kinds of weird new Microsoft Azure -related tidbits of information, a bunch of Visual Studio -related (and other) tips and tricks, and of course the blog’s namesake – SharePoint Problems.
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.
Speaking Gigs
I attend community events like SharePoint Saturdays whenever I can, and I’m lucky my employer Valo sends me all around the world to participate in bigger conferences like the SPCs.
I’m also speaking at some of these events every now and then – see below, if any of the events are coming up (or catch the materials from the latest gigs)!
You can also see a list of all my sessions and session materials.

No upcoming engagements. Would love to meet y’all again, after we’ve got a vaccine or something.
