Mono Compilation instructions

[TechnologyClassroom]

Has anyone gotten this to work with Mono? I tried building PKHeX.CLI on Debian 12 with mono and I could use some pointers. I am not very familiar with C#. I see the installer pulls the release, but I am not sure how to compile the program. I installed the mono-everything package. I tried xbuild on the csproj file. I get this failed output:

PKHeX.Everywhere/src/PKHeX.CLI$ xbuild PKHeX.CLI.csproj 

>>>> xbuild tool is deprecated and will be removed in future updates, use msbuild instead <<<<

XBuild Engine Version 14.0
Mono, Version 6.8.0.105

Microsoft in the recent years has been incorporating the work done in mono as part of its native .NET Framework.

To compile this project, just install .NET 9 SDK: https://dotnet.microsoft.com/en-us/download/dotnet/9.0

after installing, you should have access to the cli tool dotnet in your PATH

then you cd into the root folder of this repository and run:

dotnet build
