Schneider is Aiming to fully replace the Silverlight functionalities and add even more.
In the last release you should find all the traces you was using in Silverlight, I tested Electric ones on Minerville sample data and it's very easy and fast to configure
Just to add to Francesco Giovinazzo comments, we already deployed ArcFM Web for a couple of customers already.
Besides the built-in Tracing functionalities, they get the cool options of querying and filtering that are even provided as a combo for a specified extent.
Not to mention the ease of configuration and customization per user or group of users if needed without having to create multiple services.
