C# Error
CS1562 – Outputs without source must have the /out option specified
Reason for the Error & Solution
Outputs without source must have the /out option specified
The compilation could create an output file, but there was no source code file as input from which the name of the output file could be implied. For example, you may be trying to compile a metadata- or resource-only file.
Use the compiler option to specify the name of the output file.
