Hi,

I am working on a web project. The server of the project uses SignalR. I am getting this error "The calling thread must be STA, because many UI components require this" only in release version and at time when user attempts to login. When login button is pressed again this error doesn't come up. I'm not sure what could be reason and how to resolve it. Any help would be greatly appreciated.

Thanks.
