The ProGet server doesn't modify packages, except to strip embedded symbols and source code if that option is enabled on a feed. It certainly doesn't modify a package such that the folder structure is flattened.

Are you certain the package isn't flattened on the server, and in addition to that, actually being downloaded from ProGet at all (versus the NuGet cache or something like that)?

Just to clarify, .NET PDBs with "full" debugging information (i.e. Windows PDB format) are supported, it is just .NET "portable" format that is currently not supported.

Support for portable PDBs is currently an "open issue", and our initial research found that metadata information was undocumented, however since then it has been: https://github.com/dotnet/corefx/blob/master/src/System.Reflection.Metadata/specs/PortablePdb-Metadata.md

Unfortunately at this time we don't have a timetable for if or when this gets implemented.

This was a regression: https://inedo.myjetbrains.com/youtrack/issue/PG-1085

We will have a maintenance release out today to fix this.

Don't call the SOAP methods directly; that's not supported, and the communication protocols can change in maintenance versions since it's not part of the SDK.

The best way to do this would be using the Util.Agents::CreateAgentFromId method. This will return an AgentBase instance.

Once you have that, you can invoke the GetService<T>() method (with IRemoteMethodExecuter as T), and then run code on the agent with the IRemoteMethodExecuter::InvokeMethod) method to get any information about the agent you'd like.

There is also AgentBase::GetAgentStatus) method, but that's not as easy to interact with since you need to construct a context to determine if the agent is considered outdated.
