I’ve got a project that I started with the aurelia dotnet template.

```
dotnet new aurelia -ht:http2 -e:none -op:false

```

Now I’m trying to add `aurelia-ui-virutalization`. I started with  
npm install aurelia-ui-virtualization --save

Package.json now shows `dependencies: { ...,"aurelia-ui-virtualization" : "^1.0.0-beta.7"}`.

I then edited `main.js` and added `.plugin('aurelia-ui-virtualization')` to `aurelia.use`.

At this point, if I compile and run my app, I get the following browser error in `aurelia-loader-webpack.js`:

> Uncaught (in Promise) Error: Unable to find module with ID: aurelia-ui-virtualization

Can someone help me understand what I’m missing?

If you are using WebPack you may need to `import { PLATFORM } from 'aurelia-pal';` and then `aurelia.use.plugin(PLATFORM.moduleName('aurelia-ui-virtualization'))` instead.

See [https://aurelia.io/docs/plugins/virtualization#configuring-the-plugin](https://aurelia.io/docs/plugins/virtualization#configuring-the-plugin)

Thanks so much! That was the problem.
