For those early adopters who grabbed the DLP Design RFID Reader/Writer and launched into the wonderful world of BizTalk RFID in Beta 2, there may be a rude shock when you install the RTM...the device provider fails to install.

Ok, so don't panic. Here are the re-built DLP Design DSPI provider assemblies.

If you want to explore BizTalk RFID a little deeper then follow the steps below to re-build the DSPI provider from source.

If you haven't already, download the source for the DSPI provider. Mick Badran kindly linked to them in a blog post not so long ago. Unpack the compressed file and open the solution in VS 2005.

Take a look at the project references

Refresh the references to Microsoft.Rfid.SpiSdk and Microsoft.Rfid.Util assemblies found in the BizTalk RFID bin folder (C:\Program Files\Microsoft BizTalk RFID\bin for a typical install)

Build the project...Before you build, take a look at the project Build Events (Right-click DlpDesignDSPI project and select Properties). The build event uses the RfidClientConsole.exe command line tool to register and copy the DSPI assemblies to the Providers bin folder. Go explore the RfidClientConsole command line tool a bit more closely as you will cross paths with it frequently in BizTalk RFID land.

Ok...now Build the project.

In RFID Manager, the device provider should be installed and in the Registered state.

To those who are using the device simulator in BizTalk RFID, I fully recommend getting a physical RFID device, like the Dlp Design Kits we got. Actually swiping tags across the reader and seeing the HD led go nuts is a much better experience than clicking a button that's labeled "Pretend you swiped a tag"

Now you are back up and running. Enjoy!
