# Use Extism PDK for .Net to send HTTP(s) requests from inside WASM
This devcontainer is configured to provide you a DotNet SDK 8.0 and wasi-sdk 20.0.
[](https://codespaces.new/wasm-outbound-http-examples/extism-dotnet-pdk)
## Instructions for this devcontainer
Tested with Extism .NET PDK [v1.0.3](https://github.com/extism/dotnet-pdk/tree/v1.0.3),
Extism CLI [v1.5.1](https://github.com/extism/cli/releases/tag/v1.5.1).
### Preparation
1. Open this repo in devcontainer, e.g. using Github Codespaces.
Type or copy/paste following commands to devcontainer's terminal.
2. Install the WASI workload:
```sh
dotnet workload install wasi-experimental
```
3. Generate WASI-enabled .Net project:
```sh
dotnet new wasiconsole -o HTTPRequestingPlugin
```
4. `cd` into that project's directory:
```sh
cd HTTPRequestingPlugin
```
5. Add Extism PDK dependency to project:
```sh
dotnet add package Extism.Pdk
```
6. Copy HTTP example source code into project's folder to replace a generated one:
```sh
cp ../Program.cs .
```
### Building
1. Compile the example:
```sh
dotnet build
```
Build process creates 25M-sized `HTTPRequestingPlugin/bin/Debug/net8.0/wasi-wasm/AppBundle/HTTPRequestingPlugin.wasm` bundle.
### Test with Extism CLI
For testing purposes, you can invoke functions from Extism plugins with [Extism CLI](https://github.com/extism/cli).
1. Install `Extism CLI` from Github releases:
```sh
wget https://github.com/extism/cli/releases/download/v1.5.1/extism-v1.5.1-linux-amd64.tar.gz -O /tmp/extism.tar.gz
tar -xzf /tmp/extism.tar.gz -C /tmp ; mv /tmp/extism .
```
And now you have `extism` binary in current folder.
2. Run default function (it's `_start`) from extism plugin with CLI, allowing outbound connections to all hosts:
```sh
./extism call ./bin/Debug/net8.0/wasi-wasm/AppBundle/HTTPRequestingPlugin.wasm _start --allow-host '*' --wasi
```
### Finish
Perform your own experiments if desired.
