C# and .NET
Microsoft platform for building business software: C# is the language, .NET is the runtime and library set it ships with.
Also known as C# .NET dotnet
Definition
C# and .NET are the natural fit for an organisation already living inside Microsoft tools, because the same platform covers the web application, the desktop program, the background service and the reporting, with one toolchain and one support contract. Since .NET became open source it also runs on Linux, so the choice no longer decides what your servers must be.
