After doing some web research I found out that Roslyn generates a new PDB file format. So the current CCI's PdbReader implementation does not support very well this new PDB file format. For instance, it doesn't load correctly the names of local variables.
There is a nuget package called CustomMetadataFix.Microsoft.Cci.Metadata here (https://www.nuget.org/packages/CustomMetadataFix.Microsoft.Cci.Metadata
suppose to fix this problem, but it is not open source and maybe it was implemented in an older version of CCI because it doesn't have all the same classes and methods of the last CCI version.
Is there any plan to support the new PDB file format in CCI?
Thanks a lot,
