✅ How to stop Bootstrap CSS from overriding the layout.css of my Razor page?

So I've been trying time and time again to understand why I can't get my pages to look how I want them to at all! I've tried adding a colour background to my main body of my pages but it doesn't work unless I remove the bootstrap.css, but when I do that, my page looks terrible, like a coloured notepad rather than a nice website... I'm really struggling to understand how I'm meant to do the CSS Files.. I have the _Layout.cshtml...

✅ Winform with Blazor -> HotReload Slow

We've now started migrating our project to .NET 9, and we're experiencing issues with hot reload. Here's our setup: We have a Windows Forms application that serves as a host. The host contains a single Blazor WebView component which runs our main application. When making simple changes (like adjusting a div's margin (.razor file) or changing something in a cs file (non blazor)), it takes approximately 30 seconds for the hot reload to apply....

My MAUI App Cannot Be Deployed When Running Debugger?

My .net8 maui blazor app was running perfectly fine and was freshly pushed and merged while functional, but when I attempted to change the maui icon and splash screen properties of the svg's, in an attempt to use png's the app stopped working and I decided to undo everything. The problem is that now the project won't work anymore even though everything has been completely reverted and I don't know how to run it. I did the first 5 minutes of this video which doesn't really do anything weird when it broke, just a few svg properties and changing icon stuff only. https://www.youtube.com/watch?v=5cgrKARU3Bw ...

Ignore strong names

I was using way too long hunting down the reason for a CS0012, I had the assumption that a non strong named assembly reference can bind to a strong named assembly reference just not the other way around which I thought was logical. (btw an error message with more info could have been useful) But yeah, no some debugging and browsing of roslyn code base eventually made me notice that if either is strong named both must be. This means nuget packages that come shipped strong named (like newtonsoft.json) will break comparability with older libraries, potentially, and including in my case, some you don't have control over. Older versions, in most cases, works just fine in my use case....

✅ Is it possible to access a Controller's URI at runtime?

I'm not well versed in MVC structures, so this very well could be a XY problem. Let me know if it is a bad idea to begin with. I'm trying to create a GET endpoint for /collections which returns Collections. One Collection always contains a nested Model User. On its own, this is not a problem. However, I am creating my API based around application/hal+json, which requires Resources to have a link to point to their exact location....

✅ MemoryStream question

If I have a byte[], and I'm instantiating a MemoryStream with this byte array, does it occupy twice the memory? Or is the MemoryStream simply referring to the byte array instead of copying the contents in the array?

✅ How to learn data structures and algorithms?

I am trying to learn data structures and algorithms. I use neetcode.io(only free version) and Leetcode. But I don’t really have direction besides the roadmap on neetcode.io. Additionally I have a lot of questions: How many questions should I do before going to the next topic? How should I learn the topics(try to solve a problem first and then learning from the solutions, or straight up learning the topic from e.g. a YouTube video)? Are there other great recourses?...

Wrong DataContext Inference?

First of all I am still a beginner, so I might not completely know what I am saying. So I am building an Avalonia MVVM app, it is an inventory management system. I have used Postgres for the database. The problem here is, in InventoryView, the commands to edit and delete rows can not be resolved. Rider tells me that the datacontext for the commands is InventoryView, which should be InventoryViewModel, if I am right? I am very new to Avalonia, and only familiar with Winforms, which a lot different....
