I’m the lead for the Roslyn performance v-team. All object pools are designed to reduce the allocation rate and, therefore, the frequency of garbage collections. This comes at the expense of adding long-lived (gen 2) objects. This helps compiler throughput slightly but the major effect is on Visual Studio responsiveness when using the VB or … Read more

Add System.Dynamic.Runtime and Microsoft.CSharp as dependencies.
The difference is that the “full” type emits a classic windows PDB symbol file which is complex and poorly documented. The “portable” PDB format is a new open-source format that can be created and used on all platforms. You can read more information on this format at it’s documentation on the dotnet/core repo.
