Reason

The error is produced because the protoc executable expects its libraries in particular locations (in the same folder, or in the ..\include).

Solution

Follow the following steps.

STEP 1. Install below package.

STEP 2. Copy the Path of Google.Protobuf.Tools

[

STEP 3. Copy the protoc.exe file from below folder path C:\Users\manishkumar\.nuget\packages\google.protobuf.tools\3.20.1\tools\windows_x64

and Paste to

C:\Users\manishkumar.ma\.nuget\packages\google.protobuf.tools\3.20.1\tools

STEP 4. Change Execution path in command prompt.

STEP 5. Execute below command using .proto file

protoc -I="C:\Users\manishkumar\source\repos\protobuf_consoleApp" --csharp_out="C:\Users\manishkumar\source\repos\protobuf_consoleApp" "C:\Users\manishkumar\source\repos\protobuf_consoleApp\proto\*.proto"
