ReSharp3DS is an project that runs C# code on the Nintendo 3DS using nanoCLR / nanoFramework.

The project uses a C++ 3DS homebrew application to load C# assemblies compiled as .pe files, then executes them through nanoCLR.

Installation

Recommended current structure:

• sdmc:/3ds/ReSharp3DS.3dsx
• sdmc:/ReSharp3DS/bin/mscorlib.pe
• sdmc:/ReSharp3DS/apps/TestApp/manifest.json
• sdmc:/ReSharp3DS/apps/TestApp/app.pe
• sdmc:/ReSharp3DS/apps/TestApp/assets/sprite.bmp
• sdmc:/ReSharp3DS/apps/TestApp/assets/sound.wav

The launcher starts in: sdmc:/ReSharp3DS/

It can display folders and .pe applications. mscorlib.pe is ignored by the launcher.

You can open folders, go back to the parent directory, and launch .pe files from subfolders.

Folder structure example:

SD:/
├── 3ds/
│   └── ReSharp3DS.3dsx
└── ReSharp3DS/
    ├── bin/
    │   └── mscorlib.pe
    ├── app.pe
    ├── apps/
    │   └── TestApp/
    │       ├── manifest.json
    │       ├── app.pe
    │       └── assets/
