This article describes the MSB3022 error code.
Message text
MSB3022: Both 'value' and 'value' were specified as input parameters in the project file. Please choose one or the other.
Description
The Copy task can be used in one of two ways. You can specify a list that contains the destination path for each file in the source list, or you can specify a destination directory. This error occurs if you specify both a list of files and a directory.
Resolution
If you control the invocation of the Copy task, choose the most appropriate method of specifying the destination files, and remove the other parameter.
See Copy task.
