How do I determine where DLL is referenced?

Question

I have just deployed my VB.net VS2008 winforms solution to the test server.

When I did I got an error:

Unable to install or run the application. The application requires that assembly Microsoft.Synchronization.Data.Server Version 1.0.0.0 be installed in the Global Assembly Cache (GAC) first.

I however do not know why this requirement was put in place. As far as I know we did not add any reference to this DLL.

I have done searches and there are no matches for "Synchronization" or "Data.Server" etc...

It is not listed in the references folder either.

Any ideas why it's apparently referenced, but not referenced anywhere?

Answer 1

Try with Dependency Walker.

Answer 2

The assemblies you're referencing can reference other assemblies themselves (which can reference other assemblies (which can reference other...)). You can use NDepends to chase down your full dependency list.
