When running SignalR behind a load balancer, it requires sticky sessions as SignalR is an inherently stateful technology. This can prove difficult in some pieces of infrastructure since it may be shared for all sorts of applications.

This requires tye, which can be installed with the following command:

dotnet tool install --global Microsoft.Tye --version 0.11.0-alpha.22111.1
