The APIs I needed weren't public. Maybe I missed something? Feel free to push directly to the PR branch to fix.

I'm sorry, I don't quite understand how to use the link you provided to get rid of reflection here.

My task is given a MetadataReaderProvider how to obtain the uncompressed byte[] of the embedded Pdb or a Stream that I could pass to the Pdb2Xml dumper.

I see. You can use MetadataReader.MetadataPointer and MetadataReader.Length to read the data.

I'm sorry again, I'm not well-versed in pointers and unsafe code, so I really don't know how to do this.

It would be great if you could just do it yourself when you have time (not urgent).

I think PEReader should be able to read from an RVA given the position and size, and fill a byte array. Not sure if disk layout/memory layout of the PE format is relevant here.
