WoofWare.DotnetRuntimeLocator

Helpers to locate the .NET runtime and SDKs programmatically. (If you're parsing dotnet --list-runtimes, you're doing it wrong!)

Usage

See the example.

let info = DotnetEnvironmentInfo.Get ()
// or, if you already know a path to the `dotnet` executable...
let info = DotnetEnvironmentInfo.GetSpecific "/path/to/dotnet"

// identify the directories containing the framework which would execute a given DLL
let dirsToSearch : string seq = DotnetRuntime.SelectForDll "/path/to/dll.dll"
// or, if you would be running with a specific `/path/to/dotnet exec /path/to/dll.dll`:
let dirsToSearch : string seq = DotnetRuntime.SelectForDll ("/path/to/dll.dll", "/path/to/dotnet")

Troubleshooting

The easiest way to make sure we can find a dotnet is to have one on your PATH.

If you have a very strange setup, we may be unable to locate the libhostfxr library we use to find the runtimes. In that case, you can supply the environment variable WOOFWARE_DOTNET_LOCATOR_LIBHOSTFXR, which should be a full path to a libhostfxr DLL on your system. (Normally this is in /usr/share/dotnet/host/fxr/{runtime}/libhostfxr.so; you must make sure your version is from runtime 6 or greater, because the required symbols were not added until then.)
