See dotnet/blazor#193 for status updates on this work item.

For now, we can use dotnet watch run and recompile every time when the change occurs.
Just using this in csproj file :
<DotNetCliToolReference Include="Microsoft.DotNet.Watcher.Tools" Version="2.0.0" />
<Watch Include="**\*.cshtml"/>

We've hit a snag with live reload for 0.2.0, so moving this out until we can work through a more robust design.

Hi, I'm using dotnet sdk 2.2.100-preview1-009349 and blazor 0.5.1 under Mac.
Live reload doesn't work using "dotnet blazor serve". If I change some html markup in a cshtml file, the app doesn't reload itself and ever after a manual browser reload, the app display the old html content. How can I solve this?

@danroth27, what's #4056 then? Should it be closed?
