I skimmed a few Skyline .NET 10 upgrade PRs to see if there were any other common tasks we've done. (You can find these by looking through the history of global.json in some microservices).

One suggestion I found is to adopt the cleaner .slnx file format for the BlazorWorkspace.sln. But you can consider that optional / follow up if you want, not all services did it.

You might also ask some of the devs who did these upgrades (Paul, Darren, Aaron, etc) if there's anything else we should be thinking about.

- Install Node.js version 24+ (run `node --version`) which can be downloaded from <https://nodejs.org/en/download/>
- Install .NET 8 SDK (see required version in [`globals.json`](/packages/blazor-workspace/global.json)) which can be downloaded from <https://dotnet.microsoft.com/en-us/download>
- Run `dotnet --info` to verify the required version of the SDK is installed. A `v8` install is required, but it's fine if later versions are installed too.
- Install .NET SDK (see required version in [`globals.json`](/packages/blazor-workspace/global.json)) which can be downloaded from <https://dotnet.microsoft.com/en-us/download>
- Run `dotnet --info` to verify the required version of the SDK is installed. An sdk that matches the major version is required, but can have a greater minor / patch version.
- If running on an IT-managed system, set env var `NODE_USE_SYSTEM_CA=1`
- This avoids errors during `npm install` like `playwright Error: unable to get local issuer certificate`. See Node docs: [Adding CA Certificates from the System Store](https://nodejs.org/en/learn/http/enterprise-network-configuration#adding-ca-certificates-from-the-system-store).
