This article explains how to get rid of sudden and unexplainable 401 Access Denied errors when trying to authenticate against a fairly fresh Microsoft 365 / SharePoint Online tenant. This issue seems to be caused by a long-ish project to finally retire ACS – Azure Access Control service) on SharePoint (it’s retired everywhere else already!) Note: This is an updating story, as the situation with ACS is definitely… Developing. Yeah, let’s call it that. It’s a developing situation. Problem In the beginning of September (2020),…Continue reading (Literally) Breaking: Changes to app authentication on SharePoint! 😵
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.

Fixing unexpected Microsoft.AspNetCore package errors after a dependency update
This was a fun one! Suddenly, while running or debugging my ASP.NET Core 3.1 application, I started getting errors about missing assemblies.

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
2020 – Year Review
Like almost customary at this point, I decided to take a look at 2020 – which goals I had set for myself, if I hit them, and what happened on koskila.net during the year. And like last year, I thought I’d set myself a few new goals! In my last year review post, I commented on 2019: 2019 was borderline tumultuous – in 2020, I hope it’ll be slightly smoother sailing. Me, in my 2019 review Oof. Overall, 2020 was definitely not “smoother sailing”. But…Continue reading 2020 – Year Review
Graph API throws “$count is not currently supported.” when you KNOW it’s supported?
Hey, another funny case. “Funny” as in “the error message is misleading and googling didn’t really help”, but also as in “a colleague knew the answer right off the bat because he already fixed it in another project”. This time the documentation was in fact there, it just wasn’t there to be found. Anyway – what have I broken this time? Problem When you’re calling Graph API with both $filter and $count, for example like this: Instead of the expected number of found items, you…Continue reading Graph API throws “$count is not currently supported.” when you KNOW it’s supported?
“An assembly specified in the application dependencies manifest was not found” when running Add-Migration in Entity Framework Core?
Another quick one – I’m sure this doesn’t apply to all cases, but I’m still logging it in case someone (like myself) stumbles upon the issue and finds help here. I was building a solution with some Azure Functions fetching and populating data in a database, and was planning on building an UI for browsing the data at some point later on – but I actually got stuck on the second step already :) While adding the database to my project, while running Add-Migration in…Continue reading “An assembly specified in the application dependencies manifest was not found” when running Add-Migration in Entity Framework Core?

Hacktoberfest 2020
Another year, another Hacktoberfest, another haphazard participation and – as usual – another blog post a little bit late.

How to inject EF Core DbContext in an Azure Function?

How to list your git stashes?
Long story short, yes, I really had to google this, and since top results seemed to give pretty unclear (or even wrong) answers, I decided to document it for myself.
