Differences

The following are some key differences between C# and Kotlin.

Characteristic	C#	Kotlin
Syntax	C# syntax is similar to C++ and Java, with curly braces and semicolons to denote blocks and statements. It also supports LINQ (Language Integrated Query) for querying data from various sources.	Kotlin syntax is similar to Java, but with some improvements such as null safety, extension functions, and smart casts. It also supports functional programming concepts such as lambdas and higher-order functions.
Paradigm	C# supports both object-oriented programming and functional programming paradigms.	Kotlin supports both object-oriented programming and functional programming paradigms, with a focus on functional programming.
Typing	C# is a statically typed language, which means that the type of a variable is determined at compile-time.	Kotlin is a statically typed language, which means that the type of a variable is determined at compile-time. It also supports type inference, which allows the compiler to determine the type of a variable based on its usage.
Performance	C# is known for its high performance, especially when used with the .NET framework.	Kotlin is a relatively new language and its performance is still being evaluated. However, it is designed to be highly interoperable with Java, which is known for its performance.
Libraries and frameworks	C# has a large number of libraries and frameworks available, including the .NET framework, which provides a wide range of functionality for building Windows applications, web applications, and more.	Kotlin has a growing number of libraries and frameworks available, including Spring Boot, Ktor, and Android KTX.
Community and support	C# has a large and active community, with many resources available for learning and development.	Kotlin has a growing community, with many resources available for learning and development. It is also supported by Google for Android development.
Learning curve	C# has a moderate learning curve, especially for developers with experience in C++ or Java.	Kotlin has a relatively easy learning curve, especially for developers with experience in Java.
