Hey @jesperson! Is it a Blazor Server or a Blazor WebAssembly project?
I’ve been able to deploy an example Blazor WASM project with Vercel CLI and a few changes from the default project config. You can see it at blazor-wasm-five.vercel.app
There isn’t a C# runtime for Serverless Functions at the moment so I couldn’t get a server project running. But it would be possible to add if someone has the time to develop it as a community runtime.
