Hi Dario,
I have 2 adapter :
1. QuotesStreamer.HaSTC.Adapters.Data.StockListAdapte r
2. QuotesStreamer.HOSE.Adapters.Data.StockListAdapter

and i config in "adapters.xml"
-------
<?xml version="1.0"?>

<adapters_conf id="HaSTC">

<!-- Metadata provider is the Java Remote Metadata Adapter Proxy with
sockets transport. -->
<metadata_provider>
...
</data_provider>

</adapters_conf>

and I start only adapter "QuotesStreamer.HaSTC.Adapters.Data.StockListAdapt er" by config in "DotNetServer.bat" :
---------
...
rem start "StockListAdapter" /MIN DotNetServer QuotesStreamer.HoSE.Adapters.Data.StockListAdapter /host localhost /rrport 6661 /notifport 6662

start "StockListAdapter" /MIN DotNetServer QuotesStreamer.HaSTC.Adapters.Data.StockListAdapte r /host localhost /rrport 6661 /notifport 6662

start "LiteralBasedProvider" /MIN DotNetServer Lightstreamer.Adapters.Metadata.LiteralBasedProvid er /host localhost /rrport 6663 max_bandwidth=40 max_frequency=3 buffer_size=30
