I am regularly having problems building on teamcity, I've run into the licence.licx before issue, but fixed that so that is not my problem.

I started out getting this error:

# Helpers\ExcelExportHelper.cs(7, 42): error CS0234: The type or namespace name 'ExcelExporter' does not exist in the namespace 'Infragistics.Windows.DataPresenter' (are you missing an assembly reference?)

# C:\TeamCity\buildAgent\work\b56a5cef41d41d0d\AccountingManager.Presentation\App.xaml(3, 167): error MC2000: Unknown build error, 'Could not find file 'C:\TeamCity

I ended up removing all Infragistics references and re-adding them and now I have this error:

"C:\TeamCity\buildAgent\work\b56a5cef41d41d0d\AccountingManager.Presentation\AccountingManager.Presentation.csproj" (Rebuild target) (5) -> (ResolveAssemblyReferences target) -> c:\WINDOWS\Microsoft.NET\Framework\v3.5\Microsoft.Common.targets : warning MSB3245: Could not resolve this reference.

So basically now it appears I can't resolve any references.

On this note I have found using Infragistics with a build server to be nothing but trouble.  I can only assume this has something to do with the licencing, but please correct me if I am wrong.  What I do know is that if using these controls with a build server like TeamCity continues to be a problem I will have to discontinue using them on future projects.

Thanks,
