Windows Store apps run within a new set of APIs known as Windows Runtime, which supports programming languages such as C, C++, Visual Basic .NET, C#, along with HTML5 and JavaScript. If written in some "high-level" languages, apps written for Windows Runtime can be compatible with both Intel and ARM versions of Windows, otherwise they are not binary code compatible. Components may be compiled as Windows Runtime Components, permitting consumption by all compatible languages. To ensure stability and security, apps run within a sandboxed environment, and require permissions to access certain functionality, such as accessing the Internet or a camera.

What does compiling components as Windows Runtime make possible?

In the medieval Middle Eastern world, the physicist and Islamic scholar, Al-Farabi (Alpharabius, 872950), conducted a small experiment concerning the existence of vacuum, in which he investigated handheld plungers in water.[unreliable source?] He concluded that air's volume can expand to fill available space, and he suggested that the concept of perfect vacuum was incoherent. However, according to Nader El-Bizri, the physicist Ibn al-Haytham (Alhazen, 9651039) and the Mu'tazili theologians disagreed with Aristotle and Al-Farabi, and they supported the existence of a void. Using geometry, Ibn al-Haytham mathematically demonstrated that place (al-makan) is the imagined three-dimensional void between the inner surfaces of a containing body. According to Ahmad Dallal, Abu Rayhan al-Biruni also states that "there is no observable evidence that rules out the possibility of vacuum". The suction pump later appeared in Europe from the 15th century.

who stated that there was no evidence to rule out a vacuum?
Answer: Abu Rayhan al-Biruni
