I'm traversing syntax tree and need a way to catch implicit conversion. SyntaxWalker doesn't have such virtual method and SyntaxTree itself doesn't have any info about implicit conversions. What should I do?

Is having two DbContext on same base antipattern or bad approach?

In company (so there is no much freedom to do with other tools I need to solve this using EF Core), we are using CQRS with MediatR, and every command handler is wrapped in a transaction. So if something fails, we roll back the transaction. Here’s the issue: I need to save certain data even if an exception occurs. The main data should be rolled back, but part of the data needs to be saved in the database. I know I can use two separate DB contexts to solve this issue, but is this a good approach?...

✅ When should you or shouldnt you return nested data in an api call?

Let's say I have a these tables in my database, Project, Members, Task, Comments and I want to return paginated data so a user can view all their projects, then view the tasks and members associated with the project and the comments associated with the individual tasks. Would you do this as all separate queries or do one query that returns all the data nested and paginated? Here's my current thought process. ``` - Load all Projects paginated - One api call only project data...

How to host small static website

Hey guys, the website has no database and the users cannot change it's contents in any way(I believe that's what a static website means). It won't be getting much traffic as the users are around 100, I would expect a couple visits per day at most. What is the easiest way to host it, I am willing to pay for it, but would prefer a free hosting service :)

✅ How to clean up a stream of incomplete JSON data?

I'm working on adding some discord capabilities to a bot I'm working on but the data I get is really messy? I seem to just get a constant stream of data but I don't see any actual identifier of when a message ends? So I was wondering if there is any way that I could possibly keep adding a buffer to a StringBuilder and then try and extract the first json object, add it to a Channel and then remove it from the StringBuilder and keep looping it? This is 2 bits that I was working on so far.. I've cut out a lot of stuff that didn't work...
