Is it possible to use the Biztalk adapter pack whithout a Biztalk installation (Biztalk license is available)? I want to use the Biztalk Adapter for SAP RFC calls within a .NET Application (as a replacement of the SAP Connector for .NET, which is unfortunately no longer maintened by SAP and I don't can use third party products like "ErpConnect"). Makes this idea sense or not ? This questions can be also seen in conjunction of my question concerning connecting SAP and Microsoft (Microsoft and SAP)
The adapters in the Biztalk adapter pack are build on the WCF LOB adapter SDK, so it's possible to use them without a Biztalk Server installation. I think you should take a look at the SAP tRFC Client sample from Microsoft on how to implement your solution. It's located at http://msdn.microsoft.com/en-us/biztalk/cc196386.aspx.
There is a new version of SAP Connector for .NET, which will still be supported for quite some years: https://support.sap.com/connectors
