When you install ESB 2.0 guidance from the source (CTP Build 1), the ESB Configuration tool does not compile. This means that in order to configure the Databases and Web Services, you have to manually configure each of these sections by hand. When trying to compile the ESBConfigurationTool solution, the error you get is here:
The issue is that the DirectoryObjectPicker C# Class library project is referencing an Interop assembly named ActiveDs.dll. This assembly, in this build, does not have the correct signature. To circumvent this issue, one option is to try to refresh this interop assembly by re-referencing the Active DS Type Library as show here:
By doing this, an interop assembly is created using the .NET Framework SDK utility called TlbImp.exe. This process invokes the utility to create an interop assembly. However, this assembly that is created by the TlbImp utility is not signed by default.
You may be asking, "what does have to do with the DirectoryObjectPicker project?"
It just so happens that the DirectoryObjectPicker project needs to be signed and eventually installed into the GAC. Any project that needs to be signed and installed into the GAC has a constraint that says any referenced assemblies also need to be signed as well. We reach the real problem here. The original ActiveDs.dll is not signed correctly and the one created by re-referencing and using the Utility is not signed at all. There are ways in which we could just force a signature on an interop assembly, but we should not because we would be, in effect, “spoofing” the assembly. We should use the original manufacturer’s signature and use its interop version of the assembly.
Here’s the fix. Search your Root drive, and look for any file with the name ActiveDs. Chances are that you have installed other libraries or frameworks that use this fairly common assembly. It can be found inside the BizTalk Accelerators, WCF LOB adapter pack, and other .NET Frameworks. The one that worked for me is the Interop.ActiveDS.dll located inside the BizTalk RossettaNet Accelerators A4RN Msi folder:
Once you’ve found the right match, copy this assembly and place it into your DirectoryObjectPicker source folder. Add a reference to this assembly instead.
What you’ll notice at this point is that the project still doesn’t compile. The reason is because the namespaces are not quite correct. Compile the project and inside the source code file (NameTranslator.cs to be specific), where the few errors occur, add a using statement such as this:
using ActiveDs = Interop.ActiveDS;
Adding this line of code will create a Namespace alias that points to the correct namespaces. Compile the project and remove the delay signing on each of the two projects: (DirectoryObjectPicker, EsbConfigurationTool). Build and install the DirectoryObjectPicker project into the GAC, and run the EsbConfigurationTool. You’re done.
Happy ESB'ing!
