Description

Lightweight optimizer of System.Linq.Expression expressions. Just basic boolean algebra and reductions, constant and tuple/anonymous type eliminations. For side-effect free Expressions. No compilation-subjective optimizations. This is meant to be used with expressions that are not compiled but transferred to other domain.

Linq.Expression.Optimizer

Supported frameworks: Net 3.5, Net 4.5-... (and Mono), .NET Standard 1.6 (so also .NET Core)

Supported optimizations

Example as a quote. There are various other cases also.

Replace constants comparisons: 3 < 4 -> true
Remove anonymous types: new AnonymousObject(Item1 = x, Item2 = "").Item1 --> x
Cut not used condition: if false then x else y -> y
Remove not: not(false) -> true
Binary tree balancing: a or (b or (c or (d or (e or (f or (g or h)))))) -> ((a or b) or (c or d)) or ((e or f) or (g or h))
Captured closure constant ("free variable") evaluation: y = 3 and (y + x) -> (3 + x)
Execute simple math: 5 * 3 -> 15
Boolean algebra reductions:
- gather (x or y) and (x or z) -> x or (y and z)
- identity false or y -> y
- annihilate true or x -> true
- absorb x and (x or y) -> x
- idempotence y or y -> y
- complement x and not(x) -> false
- doubleNegation not(not(y)) -> y
- deMorgan not(x) and not(y) -> not(x or y)

Background

This is a side-track from SQLProvider, excelent tool that is kind of OR-mapper with auto-generated objects, so it compiles any databases to .NET-language, and works fast on design time in Visual Studio or other editors.

But I needed better SQL-queries. So this optimses .NET LINQ-expressions. These expressions were not ment to be compiled so Nessos LinqOptimizer was not the right tool. I thought that .NET would optimize these automatically, but no.
