Papercut ServerCommandProxy.DLL for Powershell 7.x Management

Body

To manage Papercut from Powershell you must build the ServerCommandProxy.dll. Papercut has directions to build it, but they are incomplete.

The Papercut directions can be found here:
Administering PaperCut with PowerShell | PaperCut

dlls compiled for Powershell 7.5.4 are attached to this article along with the relevant source code modifications to aid in recompilation at a future date.

Papercut v25.0.8

The source code for the DLL that ships with this version has 4 bugs that prevent compilation. A corrected version of the source code is attached to this document.

For the sake of documentation to fix compilation errors the following Methods need to be updated:

Line Method Change
356 BatchImportInternalUsers The parameter emailUserOnCreation is set to the wrong type, it is set to "Boolean" and it should be "Bool"
1217 SharedAccountExistsId The return value for accountId must be converted to a string. Changed "accountId" to "accountId.ToString()"
2109 BatchImportInternalUsers The parameter emailUserOnCreation is set to the wrong type, it is set to "Boolean" and it should be "Bool"
2369 InstallLicense Because of the void declaration this method is not allowed to return a value. Remove the word return.

Powershell 7.x

You will need to either know the version of .NET that Powershell was compiled against -or- install the the runtime for the version of .NET that you compiled the ServerCommandProxy.dll. The .NET version can be found on the release notes for the version of Powershell 7 that you have installed.

Powershell Release Notes can be found here: Releases · PowerShell/PowerShell
 

Powershell 7.5.4

At the time of this writing the currently shipping version of Powershell is version 7.5.4. Powershell 7.5.4 is compiled against .NET 9 and the currently supported release of the .NET SDK is .NET 10. You will need to update the ServerCommandProxy.proj file in the source folder to target .NET 9 by changing the <TargetFramework> line to net9.0

A ServerCommandProxy.proj that has been preconfigured for .net9.0 is attached to this article.
