⛓ Functional .NET standard library with an declarative approach for common tasks.

Expressif is the variable substitution syntax combined with a library of predicates and functions. Initially designed for NBi.io, Expressif allows you to define variables, transformations of these variables (with expressions and functions), in plain text, which can then be interpreted by the engine. Same can be done with predicates.

PrimeFuncPack Primitives is a core library for .NET consisting of useful extensions and predicates making work with functional pipelines, Linq, strings, the nullable feature, etc. easier.
