NETLink`

InstallNET

Updated in 14.2

launches the .NET runtime and prepares it to be used from the Wolfram Language.

configures .NET/Link to use a manually created link to a .NET runtime.

Details and Options

To use InstallNET, you first need to load .NET/Link using Needs["NETLink`"].
Only one .NET runtime is ever launched; subsequent calls to InstallNET after the first have no effect.
InstallNET works on all platforms, but on Macintosh and Linux systems you need to have either Mono or the .NET runtime installed.
The following options can be given:

"UseNETFramework"	Automatic	whether to use the .NET Framework (4.x) or the newer .NET 6 and later
"MonoPath"	Automatic	custom path to the Mono runtime, if installed in a nonstandard location
"DotnetPath"	Automatic	custom path to the dotnet runtime, if installed in a nonstandard location
"Force32Bit"	False	whether to run in 32-bit mode (only supported on Windows)

On Windows, the default value of "UseNETFramework"->Automatic will choose the older .NET Framework (version 4.x). Specify "UseNETFramework"->False to launch the modern .NET runtime (.NET 6 and later) instead.
On Macintosh, the default value of "UseNETFramework"->Automatic will choose the modern .NET runtime (.NET 6 and later). Specify "UseNETFramework"->True to launch Mono (which is the .NET Framework).
On Linux, the default value of "UseNETFramework"->Automatic will launch Mono (which is the .NET Framework). Use "UseNETFramework"->False to the modern .NET runtime (.NET 6 and later).
