How to use the right version of the WebDriver on hosted agents in Azure DevOps?

We were working on getting our Robot Framework tests running during our builds on Azure DevOps. However, using hosted agents, it was quite a struggle to get all of the dependencies on the agent and make sure the tests can access the browser on the build machine. In our case, we were running the tests in Chrome. For this, we needed Robot Framework and some of its dependencies to be installed on the machine. Luckily, that wasn’t too complicated – however, getting the WebDriver that…Continue reading How to use the right version of the WebDriver on hosted agents in Azure DevOps?

EF Core fails to load hostpolicy.dll when RuntimeIdentifier is win-x86

Ran into another interesting one when working with a .NET Core 3.0 project and Entity Framework Core – this time, RuntimeIdentifier configuration causing trouble. In short, running Update-Database (to apply code-first migrations to your local database) locally would return this, annoying error: Failed to load the dll from [runtimepath]\win-x86\hostpolicy.dll], HRESULT: 0x800700C1 An error occurred while loading required library hostpolicy.dll from [runtimepath]\win-x86\] I suspect this can happen with any x86 runtimeIdentifier, but the one I had specified in my .csproj-file was this: <RuntimeIdentifier>win-x86</RuntimeIdentifier> This value (or…Continue reading EF Core fails to load hostpolicy.dll when RuntimeIdentifier is win-x86

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

Just resolved a random issue that’s difficult enough to google, that I think it’s worth documenting! These seem to be popping up whenever you work with anything that’s fairly fresh out of 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. Basically, I just started getting…Continue reading How to fix “The type or namespace name ‘Services’ does not exist in the namespace ‘Microsoft.AspNetCore.Components’ (are you missing an assembly reference?)”

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. However, the default way to create a NuGet package, where you select a project (usually you pass the same variable to NuGet pack command that you used earlier…Continue reading Azure DevOps – how to package a single DLL?

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. What you normally use this library for is exactly the same in all versions I’ve worked with,…Continue reading How to use UriHelper or NavigationManager in .NET Core 3.0 & Blazor?

Azure DevOps build fails with “The nuget command failed with exit code(1) and error(Cannot determine the packages folder to restore NuGet packages.”

This was another peculiar one – something, that didn’t bring up too many results on Google. Always fun trying to figure out those! So, when configuring an Azure DevOps pipeline (build) for a .NET project, you might run into this annoying error: ##[error]The nuget command failed with exit code(1) and error(Cannot determine the packages folder to restore NuGet packages.

A simple graphical explanation of Blazor's effect on the web development landscape.

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. Other people have written great introductions to the tech, so I’ll stick to the problem at hand:…Continue reading HttpClient in Blazor

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. But no, it does not have a helper for getting a description of a property :) You can, however, define…Continue reading How to get the Description for a property in ASP.NET MVC 5?

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’s 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…Continue reading How to add creator/modified info to all of your EF models at once in .NET Core

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. They’d would always be null during runtime…Continue reading EF Core returns null for a Navigation property

‘__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, better document in 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 initialized. But alas, it didn’t. Not anymore. I…Continue reading ‘__generated__Index.OnInitAsync()’: no suitable method found to override

This article explains the current terminology Microsoft uses around your different pages in SharePoint.

Microsoft has been known for their less-than stellar track record of figuring out easy and descriptive names for their products.

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 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!), we’re getting one step closer to that, as we’re given an…Continue reading How to Teamsify an SPFx solution?

Microsoft Teams context in SharePoint Framework client-side code.

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.

How to update SharePoint Framework for an SPFx webpart?

Instead of being stuck on whatever version your SPFx project was originally created with, it’s possible and sometimes required to upgrade it afterwards to gain access to newer functionalities like integration with Microsoft Teams. This process, to me, is comparable to updating the .NET Framework version in your classic web application projects – while it’s sometimes a matter of simple configuration change and a rebuild, most of the time there’s a bunch of steps included and not all of them might be obvious or anywhere…Continue reading How to update SharePoint Framework for an SPFx webpart?
