    How to fix "The type or namespace name 'Services' does not exist in the namespace 'Microsoft.AspNetCore.Components' (are you missing an assembly reference?)"

    I have just resolved a random issue that's difficult enough to google so I thought it would be worth documenting! These seem to be popping up whenever you work with anything that's fairly fresh out of the oven... This particular case revolves around Visual Studio being incredibly obnoxious and starting to throw a ton of errors on code that worked five minutes prior. In my case, the error happened after updates to Visual Studio. Always fun. Symptoms The errors started popping up in Visual Studio.

    Azure DevOps - how to package a single DLL?

    Okay - a quick piece of documentation that was a bit lackluster, so it's again a good idea to log somewhere. How to package a simple DLL that's a result of your Azure DevOps Pipeline? In my particular case, I have configured a post-build step to obfuscate the DLL, that's first built by MSBuild. That works nicely.

    How to use UriHelper or NavigationManager in .NET Core 3.0 & Blazor?

    Just a quick piece of documentation, as this piece of code, has changed in different versions of .NET Core 3.0 so far a few times. Need to have things like this written down somewhere! UriHelper / NavigationManager with .NET Core 3.0 Both of these helper libraries do essentially the same thing: navigate/browse/redirect the user to a different address, component, page or view in or by your web app.

    HttpClient in Blazor

    Blazor is a new (ish) framework for building web UIs with C#. It either uses SignalR to manage connections between your client-side and server-side code or even compiles directly to WebAssembly, in both cases cutting out the need to write any pesky JavaScript yourself - pretty neat, if you ask me! However, developing your web apps with Blazor is a bit different from using ASP.NET MVC, for example.

    List of Azure Regions, where Application Insights is available

    This article describes the Azure regions, where Azure Monitor Application Insights is available. Azure regions A region is a set of data centres deployed within a latency-defined perimeter and connected through a dedicated regional low-latency network. Depending on who's talking, regions are sometimes called locations, geolocations or just geos. Azure regions give customers the flexibility to deploy their applications where they need to.

    How to get the Description for a property in ASP.NET MVC 5?

    This post describes the easiest way to show description texts for properties in ASP.NET MVC 5. Sounds simple, right? We can use something like @Html.DescriptionFor(x => x.Property) , right? Alas, it's not that straightforward. A bit surprisingly, there's no ready-made helper function for this. I'm saying "surprisingly", because I feel like MVC 5 really already has all the bells and whistles - AND the kitchen sink.

    How to add creator/modified info to all of your EF models at once in .NET Core

    This is a tip that should often be the first thing you do in your projects with database backend, no matter which technology you use: Add some basic info about modified and created times, and the user information - so that if something happens, everyone will know who to blame 😉 There are a lot of great blog articles describing how to do this in .NET Framework, but not that many for .NET Core. It's very similar, but not the same. I learned that by copy-pasting code from the former to the latter.

    EF Core returns null for a Navigation property

    This article describes how to fix a situation, where you can't use any of the navigation properties of your Entity Framework Core entities, since they are all null, despite data being in the database for sure. So, another day, another error. This time I can't blame SharePoint, since I just messed up with ASP.NET Core and Entity Framework Core. :) Symptoms No matter what I'd do, I was getting null values for my navigation properties on my entities.

    '__generated__Index.OnInitAsync()': no suitable method found to override

    Welp - just ran into this one, and as I expect others to encounter the same issue, I'd better document it right away! So in Blazor, I was crafting a simple component that'd display some data in a nice way. Being lazy and crafty, I thought I'd copy-paste some similar code from an earlier POC I had built since I knew it worked. The component was overriding a method called "OnInitAsync", and it just nicely fetched data after initialisation. But alas, it didn't. Not anymore.

    Au revoir Canada, bonjour Finland.. Eh?

    Is this seriously my first ACTUAL post about Canada? What a major gap in my content! However, living in Canada has been fairly hectic (with the work, family and trips), so I haven't been able to write much about our life here - unlike when we were living in the States . Which, conveniently, brings me to the main point of this rambling - This post works as an announcement of sorts: I'm wrapping up my life in Canada, and moving back to Finland.

    Thanks for coming to my session at SPS Charlotte 8/10/2019!

    This is just a quick update to share my materials from my SharePoint Saturday Charlotte 2019 session. What a fun event - and a cool city! It was a pleasure getting to know the local community and visiting a new state. Thanks to the local user group (and the conference organizers) for having me! Charlotte - what a beautiful city! Charlotte seems like a really lively city.

    How to Teamsify an SPFx solution?

    This post describes how you can modify your SPFx webparts to make them compatible with usage in Microsoft Teams. I'm also showing some basic ideas of what you can do in the code to make the integration more useful! Why would we do this? Who wouldn't want to just develop once and then run their code everywhere? Now with SPFx (SharePoint Framework), 1.8 being out (and 1.9 being out for a while before being pulled!

    How to solve the error "Property 'microsoftTeams' does not exist on type 'WebPartContext'."

    This article explains how to fix an issue where you're just minding your own business, trying to access the Microsoft Teams context in your SPFx webpart's WebPartContext via the built-in property microsoftTeams, but you run into an issue. Simple stuff, but it's still easy to run into this one, so I think it's worthwhile to document the solution somewhere. Problem Most likely, the line causing you issues looks something like this: this.context.microsoftTeams.

    I got an awesome, (kind of) last-minute opportunity to join a crew of awesome speakers at SharePoint Saturday Charlotte (NC) on the 10th of August, 2019, and I was super happy to jump on it! I'll be presenting about extending Microsoft Teams with some SPFx goodness. Last time, the session spurred so many questions I had trouble keeping up - pretty awesome! Having never been to Charlotte, I'm super excited about this trip.

    How to resolve build failing with .NET Core 3 and Microsoft.AspNetCore.Mvc.Versioning

    Whilst building a proof-of-concept on .NET Core 3.0 preview 7 I ran into issues when developing web APIs. This release is production-ready (according to Microsoft -see below), but every now and then you run into really unintuitive and sometimes surprising issues. Go Live NET Core 3.0 Preview 7 is supported by Microsoft and can be used in production. We strongly recommend that you test your app running on Preview 7 before deploying Preview 7 into production.

    How to resolve issues when loading DLLs in PowerShell?

    This post describes a few different things that can (and will) go wrong when you're trying to load DLLs in PowerShell , and a couple of ways you can try to fix them. Typically, you'd run into an error message like "Exception calling LoadFrom with 1 argument(s): Could not load file or assembly.... " These issues most typically arise when you're running a PowerShell script that depends on certain DLLs to be loaded (to then execute some of the methods from them).

    Okay - another simple one. When you're creating a new Office Group (or "Unified Group", as they're called as well), you might get an error for the alias already being used. Pretty simple, but still - let's see how to fix it. Problem So, this error pops up, while you're trying to create a new Office Group: The alias is being used by another group in your organization.

    How to fix Microsoft.AspNetCore.Mvc.TagHelpers not being rendered!

    Ha - another one, that ended up being a simple fix, but since nobody actually explains it well, took me an hour to figure out. This post ended up being another example of my "I'm going to document every single fix that took me more than 10 minutes to figure out, since that'll help me (and others) the next time the same issue arises." blogging strategy. Snappy name, right? 😅 Ah, well, naming things is really, really difficult. Anyway, I ended up banging my head to the wall for a while.

    Sync local repo with the original on GitHub (Git merge upstream)

    This is one of those "note to self" -kinds of entries. This workflow is probably so natural to a lot of you all, that you won't need to ever google it - but since I don't do that much development using git with the full "fork - clone - branch - submit pull request" -process (which is really typical with GitHub - and I guess Open Source in general), I always need to look up the instructions on how to add pull any changes from the original repository to yours.

You typically get this error, when your app is trying to authenticate your users against Azure Active Directory. I have been posting about different versions of the Azure Active Directory authentication errors (different errors with AADSTS -codes) a lot - I'll need to find a better way to categorize them in the future.

There are different methods available for Azure and your local development environment. Problem Azure Functions are awesome. But by default, your tools for gathering information without some additional configuration are not that great.
