## Install
|
||||
|
||||
Download [Mono WebAssembly support on Jenkins](https://jenkins.mono-project.com//job/test-mono-mainline-webassembly/) by
|
||||
grabbing the latest build's Azure Artifact.
|
||||
|
||||
[mono-wasm-03914603a3b.zip](https://jenkins.mono-project.com/job/test-mono-mainline-webassembly/71/label=highsierra/Azure/processDownloadRequest/71/highsierra/sdks/wasm/mono-wasm-03914603a3b.zip)
|
||||
|
||||
Expand that into this directory.
|
||||
|
||||
|
||||
|
||||
## Build
|
||||
|
||||
```bash
|
||||
csc /nostdlib /target:library /r:managed/mscorlib.dll /r:managed/Ooui.dll /out:managed/Ooui.Sample.dll ooui-sample.cs
|
||||
```
|
||||
|
||||
|
||||
## Run
|
||||
|
||||
```bash
|
||||
python server.py
|
||||
```
|
||||
|
