Microsoft .NET Framework 4.5.50709

The .NET Framework is Microsoft’s comprehensive and consistent programming model for building applications that have visually stunning user experiences, seamless and secure communication, and the ability to model a range of business processes. The .NET Framework redistributable package installs the .NET Framework runtime and associated files required to run applications developed to target the .NET Framework. The Microsoft .NET Framework 4.5 is a highly compatible, in-place update to the .NET Framework 4. By using the .NET Framework 4.5 together with the C# or Visual Basic programming languages, you can write Windows Metro style apps. The .NET Framework 4.5 includes significant language and framework enhancements for C# and Visual Basic so that you can harness asynchrony, the blending of control flow in synchronous code, a responsive UI, and web app scalability.

The Microsoft .NET Framework is a software component which can be added to the Microsoft Windows operating system. It provides a large body of pre-coded solutions to common program requirements, and manages the execution of programs written specifically for the framework. The .NET Framework is a key Microsoft offering, and is intended to be used by most new applications created for the Windows platform. The pre-coded solutions in the namespaces form the framework’s class library and cover a large range of programming needs in areas including the user interface, data access, cryptography, web application development, numeric algorithms, and network communications. The functions of the class library are used by programmers who combine them with their own code to produce applications. The framework is intended to make it easier to develop computer applications and to reduce the vulnerability of applications and computers to security threats.
