.NET Runtime Docker build tools missing openssl

Hi, I am trying to build a modified .net runtime using docker and I get the following error:

Could NOT find OpenSSL, try to set the path to OpenSSL root folder in the system variable OPENSSL_ROOT_DIR (missing: OPENSSL_CRYPTO_LIBRARY OPENSSL_INCLUDE_DIR)

I cloned the repo locally and ran this :

docker run --rm -v (my windows path here):/runtime -w /runtime mcr.microsoft.com/dotnet-buildtools/prereqs:azurelinux-3.0-net9.0-cross-amd64 ./build.sh --subset clr --configuration Checked

Blazor index page captures static files

I am trying to learn .NET Blazor. My aim is to create an question taking app where the correct questionare is rendered by either the root domain ("default questionare" depending on the domain used to access the service), id or slug. I have app.UseStaticFiles() in my pipeline before app.MapRzorComponents<App>() but the component is still triggered by static files. Program.cs...

per pixel collision

Hi, I was just curious if anyone might know how to impliment per pixel collision into a project? I'm making a game for my A level Computer Science course - it's c# Monogame. The per pixel code is in each class that needs it, but how would I go about implimenting it in the game itself, and furthermore, should I put the code in a globals class instead? Thanks for any help in advance. I've attached screenshots of my code and where it needs to be used.

Data fetching in components?

I'm using Blazor Server. I have set up a partial class called DataContextComponent that uses DBContextFactory to create an instance of dbContext for the lifetime of that component. I thought this would be enough to keep components isolated, but I'm finding that if there is a parent and child component that both inherit from DataContextComponent and fetch data using EF Core, I get an error saying "a second operation was started on this context instance before a previous operation completed." Am I doing something wrong? I'd like to make reusable components that fetch their own data that I can use throughout the application. Is this an anti pattern?...
