1Simple Code to Solve Complex Problems
2F# Understands Your Data
Thanks to F# type providers and query expressions, developers can easily access both data and its schema, turning the data source types into F# types on the fly. This general mechanism can be used to provide uniform access to data sources, Web services, or even custom schemas and protocols.
Case studies and user reports consistently show that F#’s strong type system reduces software bugs. Units of Measure further increase these benefits by preventing code from accidentally combining inches and centimeters, dollars and euros, or any custom units.
Developers can use a functional language and have good tooling. F# is included in Visual Studio and includes such productivity boosters as source debugging, profiling and unit testing.
Modern applications and services must scale—not only across multiple cores, but also to the cloud. Using F# parallel computations, programs can scale with the capabilities of the hardware. To implement highly scalable server-side systems, F# asynchronous programming provides a clean and reliable programming model.
8Multicore and Asynchrony
As a .NET language, F# features modern, high-performance just-in-time (JIT) compilation to native code. F# code runs unchanged on both 32-bit and 64-bit systems by using the instructions available on the target architecture. The resulting code runs at the same speed as Microsoft C#, and in some cases, faster.
10Reduced Complexity, Enhanced Reuse
F# makes it easier to write functional programs, which eliminate complex time and state dependencies. This helps prevent bugs, makes unit testing more straightforward, simplifies refactoring and promotes code reuse.
