## C# code style
- Code should be formatted with `dotnet format` or Rider's built-in formatter.
- Variables should *always* be declared using `var`,
unless the correct type can't be inferred from the declaration (i.e. if the variable needs to be an `IEnumerable<T>`
instead of a `List<T>`, or if a variable is initialized as `null`).
- Variables should always be declared with their type name, unless the type is obvious from the declaration.
(For example, `var stream = new Stream()` or `var db = services.GetRequiredService<DatabaseContext>()`)
### Naming
