Finally, since C# version 7.0, the language has native syntactical support for the construction, deconstruction, and manipulation of tuples as ValueTuple instances; this also provides for the arbitrary renaming of the tuples' constituent fields (as opposed to Tuple, where the fields are always named Item1, Item2, etc.).
Unlike Java, C# additionally supports operator overloading. [93] Since version 2.0, C# offers parametric polymorphism, i.e. classes with arbitrary or constrained type parameters, e.g. List<T>, a variable-sized array which only can contain elements of type T.
Also, one namespace can spread over several assemblies. In large designs, an assembly may consist of multiple files that are held together by a manifest (i.e. a table of contents). In C#, an assembly is the smallest deployment unit used, and is a component in .NET. In Java, it is a JAR file. [1]
Once this compiler has been tested and can compile itself, now version X+1 features may be used by subsequent releases of the compiler. Stage 3: a full compiler is produced by the stage 2 full compiler. If more features are to be added, work resumes at stage 2, with the current stage 3 full compiler replacing the bootstrap compiler.

Traditionally, .NET apps targeted a certain version of a .NET implementation, e.g. .NET Framework 4.6. [5] [6] Starting with the .NET Standard, an app can target a version of the .NET Standard and then it could be used (without recompiling) by any implementation that supports that level of the standard. This enables portability across different ...
Microsoft later developed the C# ("C Sharp") language as the primary language for the .NET platform, which was in many ways influenced by Java; subsequently the .NET Framework shares many ideas in common with Java. Much like Java, C# is compiled to a type of bytecode (called CIL), and runs on top of a virtual machine called the Common Language ...
C# is case sensitive and all C# keywords are in lower cases. Visual Basic and C# share most keywords, with the difference being that the default Visual Basic keywords are the capitalised versions of the C# keywords, e.g. Public vs public, If vs if. A few keywords have very different versions in Visual Basic and C#:
