Hi

The .NET library has undergone a couple of revisions since version 1.0
(please, check the details in the Changelog).
In particular, the 'Lightstreamer.DotNet.Utils.StringTokenizer' class is no longer exposed in the interface, as it has always been intended for internal use only.
The sample StockListDemo code, which included a reference to this class, has now been fixed, by including a personal copy of the StringTokenizer class code.
Hence, you can find this code in
DOCS-SDKs\sdk_adapter_dotnet\examples\DotNetStockListDe mo\src_metadata_adapter\LiteralBasedProvider.cs
and copy it in your adapters.

If you move to the current Server, upgrading DotNetAdapter_N2.dll is recommended, because the Adapter Remoting Interface protocol has been also extended from version 1.0 to version 1.1 in the meantime.
If you need to temporarily use the old DotNetAdapter_N2.dll, then you must also keep the old version of the Proxy Adapter (i.e. of ls-proxy-adapters.jar).
