Convert from MSSql to MySql

I'm trying to convert this MSDoc tutorial project from a local instance of MSSql to a MySql server. I'm fairly certain I've gotten all the configuration correct, except the syntax differences of MSSql to MySql. (i.e nvarchar) I pushed it to GitHub if someone is able to take a peek at it. Thanks in advance. https://github.com/Cykotech/RazorPagesMovie...

✅ FileNotFoundException: Could not load file or assembly. The system cannot find the file specified.

I'm modifying an application using AsmResolver and adding a new assembly into the module references, but for some reason .NET can't find the referenced assembly even though it's right there in the same folder as the one I'm editing. Attached is a minimum reproducible example, and a video showing what's wrong. I also tried editing the .deps.json file, since this guy https://discord.com/channels/143867839282020352/1288099229834805248/1288099229834805248 had success with that and a similar problem,...

EF Core - Intermediate table or Navigation Properties?

Hi everyone, A beginner question here. I’m working on a .NET project using Entity Framework Core and SQL Server. I have two entities, Organizations and Modules, where an organization can have multiple modules, and a module can belong to multiple organizations. I initially thought of creating an intermediate table OrganizationModules to handle this many-to-many relationship. My question is: With Entity Framework Core, do I still need to explicitly define this intermediate table, or can I just rely on navigation properties (ICollection<Module> in Organization and ICollection<Organization> in Module) and let EF Core handle the join table behind the scenes? ...

✅ Razor page not updating properly

I'm going through the MS Docs tutorial on Razor pages and I'm adding the search feature. My main issue is that even though my query updates the model appropriately, the page itself does not change. I've also made sure to clear the cache in case that was the issue.

Many To Many relationship with cascading for both entities

Hello, I'm wanting my many to many relationship to cascade delete when either entity is deleted. My issue is I can only set one to DeleteBehaviour.Cascade at a time without it erroring. If I set both to cascade, it tells me an entity can't have multiple cascade paths. I'd like to be able to delete either Application or User and it auto delete their Followers relationship.

So after each step you want to validated the mocked classes / the result of the StepN function. StepN only has sense if StepN-1 had run correctly. (For now I'm just talking about the ideal "good behavior" like testing for NotThrowException and not for TestThrowException")...
