Manual sweep of all 42 IDE0028 sites flagged by SonarQube — `dotnet format
analyzers --diagnostics IDE0028` declined to fix these (no .editorconfig
opt-in for `dotnet_style_prefer_collection_expression`), so applied by
hand. The repo already targets `<LangVersion>latest</LangVersion>` on
net8.0, so C# 12 collection expressions are available.
Pattern: `new List<T>()` / `new Dictionary<K,V>()` / `new ArrayList()` /
`new()` -> `[]` for empty; `new List<T> { ... }` -> `[...]` for literal.
24 files touched in src/{EFCore, LinqToSql, Query, Snowflake, SqlBreakdown,
SqlServer}; tests untouched (no IDE0028 sites in test code).
Build clean (35 warnings unchanged from baseline, 0 errors). All tests
remain green.

Applied via `dotnet format analyzers --diagnostics CA1854 --severity info`.
Eliminates the duplicate hash lookup in the
`if (d.ContainsKey(k)) d[k]++ else d[k] = 1` pattern. The fixer rewrites
the conditional to `if (d.TryGetValue(k, out var value)) d[k] = ++value;`
which is semantically identical but does the lookup once.
4 files touched.
