LiteDB: A .NET embedded NoSQL database
Before checking this out, people might want to take a look through the issues and pull requests of which there are 500+ and 50+ respectively [1]. I was really optimistic about this project and it was headed in a great direction, but it's not in a production ready state, and it seems that the main guy behind it has decided to move onto other things. It's been about a year since there was any significant activity.
I just mention this because a lot of these little issues might only become more apparent after integrating the db into your project and so it can be a bit annoying. I ended up swapping to Linq2DB [1]. It's something, more or less, similar offering an ORM/LINQ type system as well as the ability to also use direct SQL if desired. But the neat thing is that it also uses a standardized API for the LINQ query language, so you can do things like swap from SQLite to PostgreSQL in one* line of code, so long as you're not using any provider specific extensions.

Flyweight: An ORM for SQLite
I had a positive experience with Linq2db? https://github.com/linq2db/linq2db
I mention because I had something of the opposite experience with it. It not only ended up yielding the correct queries, but I saw a significant increase in performance. And the neat thing about it, beyond ORM and linq-to-sql, is a common interface amongst providers - so you can do things like swap from SQLite to Postgres with 1 line* of code, so long as you're not using provider specific extensions.

.NET 6 - ORM vs Stored Procedures - Azure Functions + SQL Databases
Temporary tables are covered by linq2db. But better to show Stored Proc maybe your final query just needs several CTE which also supported by linq2db.
