I downloaded the EventStore.Client nuget and discovered that out of box, it won’t work without some changes. I see that what happened is that EventStore.Client was compiled against protobuf-net 22.214.171.1244, but the nuget specifies 126.96.36.1991 as the dependency. I am sure you could fix this with some assembly redirects, but it would be better if the package was either a.) compiled against 601 or b.) the nuget spec was updated to point to 594.
