I think this is more of a general

问题 During running a dotnet console application I encountered this error. I ran it from a directory that had the .dll and .pdb file copied into it. What is the cause of this error? 回答1: the deps.json and runtimeconfig.json must also be copied into the directory that the .dll is invoked in. Without these files you will encounter this error.
