## What it is
IKVM is an implementation of Java for the .NET platform, providing a JVM implemented in .NET along with a bytecode-to-IL converter. It lets you run compiled Java code on .NET Framework/.NET Core or convert Java bytecode (JARs) into .NET assemblies without porting source code.

## Use cases
- run java applications on .net
- convert java jar files to .net dll assemblies
- use java libraries from c# projects
- execute java bytecode on .net core without a jvm
- embed a java runtime in a .net application
- interoperate between java and .net code

## When to choose
- you need to reuse existing Java libraries in a .NET project without rewriting them
- you want to deploy Java applications on machines where only .NET is available
- you need Java SE 8 runtime functionality on .NET Framework 4.7.2+ or .NET 6+

## When to avoid
- you need to convert Java source code to C# source code
- you need to run .NET code inside a Java environment
- you require Java features beyond Java SE 8
- you need a full modern JVM with the latest Java language features

## Facets
- artifact type: library
- maturity: active
- function: compiler, interpreter, sdk, developer-tools
- domain: developer-tools, cross-platform, programming-languages, compilers
- platform: dotnet, windows, cross-platform
- tags: jvm, java, bytecode-to-il, java-interop, openjdk, nuget, linux, macos
