Problem

Normally PostSharp runs fine on unattended build servers. So on our global Jenkins continuous integration server PostSharp does the job.

But on my local TeamCity continuous integration server I got the following error:

POSTSHARP error PS0127: The aspect 'EsriDE.Commons.Logging.Aop.PostSharp.LoggingAspectAttribute' uses non-licensed features (Basic Features). Please visit http://www.sharpcrafters.com/ to acquire a license of PostSharp. 

POSTSHARP error PS0154: Information regarding the previous message: the installed user license is: "". 

POSTSHARP error PS0060: The processing of module "EsriDE.Maintenance.LoginExtension.dll" was not successful.

Okay – so install the license via a target in the developer tree. Like described in

Configuring PostSharp - Creating a file PostSharp.Custom.targets or Deploying License Keys for a Team

This throws a new error:

C:\Program Files (x86)\TeamCity\buildAgent\work\bf9b0bb7766c4536\lib\Nuget-Packages\PostSharp.2.1.5.1\tools\PostSharp.targets(173, 5): Property 'PostSharpLicenseKey' is deprecated.

and indeed: this option was discontinued

Announcing PostSharp 2.1 CTP 2 (see section “License Management”)

Solution

Note to self: RTFM

Deploying PostSharp into a Source Repository - Adding PostSharp to your project using PostSharp HQ

Activate the license you got with the one of the first mails from SharpCrafters and everything works like expected.
