RulesEngine
Rules Engine is a package for abstracting business logic/rules/policies out of the system. This works in a very simple way by giving you an ability to put your rules in a store outside the core logic of the system thus ensuring that any change in rules doesn't affect the core system.

## v3.1.0 Bug-fix release
- added: #297 Add custom Constant to string output in the ToCSharpString and ToExpressionString
- added: #303 Add CompilerFlags.ThrowOnNotSupportedException and throw NotSupportedExpressionException when the flag is passed to CompileFast
- fixed: #301 Another case of the InvalidOperationException in the Mapster
- fixed: ListInit compilation for the Dictionary
- fixed: the lookup for the non-public property setter
## v3.0.5 Bug-fix release
- fixed: another case in #301 InvalidOperationException in the Mapster
- fixed: multiple problems with the TryCatch C# and Expression string output
## v3.0.4 Bug-fix release
- fixed: #302 Error compiling expression with array access
## v3.0.3 Bug-fix release
- fixed: #301 InvalidOperationException in the Mapster
- fixed: small bugs in the Lambda ToCSharpString output
## v3.0.2 Bug-fix release
- fixed: #300 Bad label content in ILGenerator in the Mapster benchmark with FEC V3
- fixed: Small issues with the `ToCSharpString()`, specifically in the TryCatch, and the Goto, and the Label expressions
## v3.0.1 Bug-fix release
fixed: #298 LightExpression with the NewExpression of 4 arguments has ArgumentCount = 3
## v3.0.0 - Major feature release
This version contains a lot of fixes and improvements and as-little-as-possible breaking changes.
### **FastExpressionCompiler** and **FastExpressionCompiler.LightExpression**
- Performance and memory consumption are improved, especially for the expressions with the closure and for expressions with the nested lambdas.
- More expression types are supported.
- Many fixes in the IL Emit.
- Added `ToCSharpString()` extension method to output the compile-able C# code described by the expression (tries hard).
- Added `ToExpressionString()` extension method to output the valid expression construction syntax, so given an expression object you'll get e.g. `Lambda(New(...))`.
- Added optional `enum CompilerFlags { Default, NoInvocationLambdaInlining, EnableDelegateDebugInfo}` parameter for the compilation
- `EnableDelegateDebugInfo` adds the diagnostic info into the compiled delegate including its source Expression and C# code. Can be used as following:
```cs
var f = e.CompileFast(true, CompilerFlags.EnableDelegateDebugInfo);
var di = f.Target as IDelegateDebugInfo;
Assert.IsNotNull(di.Expression);
Assert.IsNotNull(di.ExpressionString);
Assert.IsNotNull(di.CSharpString);
```
### **FastExpressionCompiler.LightExpression**
- Now includes the `ExpressionVisitor`.
- Improves the compatibility (the drop-in replacement) between the `FastExpressionCompiler.LightExpression.Expression` and the `System.Linq.Expression`.
- Decreasing the memory consumed by the created expressions partially via implementing the `IArgumentProvider` and `IParameterProvider` for some expressions.
