.NET HDK Discussions

We will soon also begin work on the .NET HDK to open up the amazing Holochain to the massive .NET & Unity ecosystem’s, which will help turbocharge the holochain ecosystem we are trying to build…

.NET supports compiling to WASM so we know this is possible…

We are looking for devs who would be interested in this exciting mini-project, so if you are interested please get in touch! We look forward to hearing from you!

Just as with NextGenSoftware.Holochain.HoloNET.Client, this project may be split out into its own repo and then linked to this one as a sub-module in future…

We have been tracking a number of different solutions to allow .NET to compile to WASM and the most promising so far is CoreRT (a AOT (Ahead Of Time) Compiler for .NET Core):

dotnet/corert/blob/master/Documentation/how-to-build-WebAssembly.md

# Build WebAssembly #

## Build WebAssembly on Windows ##

1. Install Emscripten by following the instructions [here](https://kripken.github.io/emscripten-site/docs/getting_started/downloads.html). 
2. Follow the instructions [here](https://kripken.github.io/emscripten-site/docs/getting_started/downloads.html#updating-the-sdk) to update Emscripten to 2.0.1 ```./emsdk install 2.0.0``` followed by ```./emsdk activate 2.0.0```
3. Install [Firefox](https://www.getfirefox.com) (for testing).
3. Get CoreRT set up by following the [Visual Studio instructions](how-to-build-and-run-ilcompiler-in-visual-studio.md).
4. Build the WebAssembly runtime by running ```build.cmd wasm``` from the repo root.
5. Run the WebAssembly "Hello World" test by running ```C:\corert\tests\runtest.cmd wasm```.

## Build WebAssembly on OSX ##

1. Install Emscripten by following the instructions [here](https://kripken.github.io/emscripten-site/docs/getting_started/downloads.html). 
2. Follow the instructions [here](https://kripken.github.io/emscripten-site/docs/getting_started/downloads.html#updating-the-sdk) to update Emscripten to the latest version.
3. Get CoreRT set up by installing [Prerequisites](prerequisites-for-building.md).
4. Build the WebAssembly runtime by running ```./build.sh wasm``` from the repo root.
5. Run the WebAssembly "Hello World" test by opening it in [Firefox](https://www.getfirefox.com).

## Build WebAssembly on Ubuntu 16.04.3 ##

This will allow managed C# code to be compiled into any native language including WASM.

The .NET HDK is now being actively developed… stay tuned for exciting news soon…

kcottrell · March 8, 2021, 1:59pm

Any updates on this .NET HDK

pqcdev · March 9, 2021, 3:59am

its 90% ready… @carolyn @thedavidmeister @Connoropolous any luck troubleshooting Ellam’s issues with RSM on his PC?

I’m helping with the Rust HDK part for HoloOASIS

thedavidmeister · March 10, 2021, 6:14pm

seemed like the latest issue was needing to add the wasm target to the rust compilation - About the RSM Technical Discussion! category

thedavidmeister · March 11, 2021, 5:27am

note that while the HDK interface is relatively stable and can be implemented in anything with wasm+messagepack, the holochain conductor likely has bugs/gaps on native windows

if anyone can test and develop PRs for windows for anything missing that would be awesome

all good if not, we will keep working towards it
