C# is the most productive production language - it exposes a lot of functional conveniences along with the robustness of strong typing. And they're finally embracing the open source community - a huge plus.

#Language Features We use the basic syntax (for, foreach, if,while) and object oriented constructs (classes, very simple inheritance).

We also use lambdas and block methods extensively, an intermediate level programming construct, but in a very formulaic and predictable way.

Personally, I really like HAML. Not having to use open and close tags is a huge time saver. As a result, writing markup with HAML is much more pleasant. HAML essentially forces you to be very strict about spacing, organization, and structure. It also makes the markup easier to read. Protip: I use this pretty frequently: htmltohaml.com

PrometheanTV has used .NET and C# for several back-end applications and services including the Morphic Video Task System utilized to stream video assets to a variety of video delivery platforms including, Akamai, Brightcove, and others.

C++ is used in Shiro (https://github.com/Marc3842h/shiro).

C++ is a high performance, low level programming language. Game servers need to run with fast performance to be able to reliably serve players across the globe.

Unity3d builds the app and scripts are written in C#. It receives first class support from the Unity3d developer and most plugins exist in C# in comparison to Javascript (the other supported scripting language)

The most latency sensitive parts are written in C++. Due to our interconnected services architecture, we use either Python or C++ for each service, with the performance critical parts being C++14.

The main Carbonmade backend / API is written in C# and is ready to run on the CLR. We currently host on Windows but are preparing to migrate to Linux when the CoreCLR stabilizes.

originally used c# a decade ago when writing the tools for superman returns at my stint with electronic arts, have used it again recently for developing in unity.

Used to write PHP extensions - AZTEC Decoder - License Driver scan - Axis2/C to PHP wrapper and Job-scheduler - Barbershop

Performance, zero-overhead abstractions and memory safety of the modern C++ language make this the perfect language for the project.

The main programming language of ApertusVR. C++11 & CMake provides multi-platform targeting. The architecture is modular.
