ailed to merge configuration files: System.Data.DuplicateNameException: The name 'configuration' is invalid

[lwiechec]

Hi, I just started using ILRepack. I try to create a single EXE for my application which is a quite thin layer on top of NUnit 2 GUI runner.

At the end of repacking, I can see this:

VERBOSE: Processing XAML resource paths ...
INFO: Writing output assembly to disk
ERROR: Failed to merge configuration files: System.Data.DuplicateNameException: The name 'configuration' is invalid. A DataTable cannot have the same name of the DataSet.
   at System.Data.DataTableCollection.BaseAdd(DataTable table)
   at System.Data.DataTableCollection.Add(DataTable table)
   at System.Data.Merger.MergeSchema(DataTable table)
   at System.Data.Merger.MergeTableData(DataTable src)
   at System.Data.Merger.MergeDataSet(DataSet source)
   at System.Data.DataSet.Merge(DataSet dataSet, Boolean preserveChanges, MissingSchemaAction missingSchemaAction)
   at System.Data.DataSet.Merge(DataSet dataSet)
   at ILRepacking.ConfigMerger.Process(ILRepack repack)

In the end I do get my exe, but running it throws an error; application also has different version and file descriptor - it lists now one of the dependencies.

I guess the - entry point is incorrect... can you help?

This would highly depend on your app.config files.
Check if you can purge some empty/not used nodes in the config files

We're seeing the same error message:

I don't pretend to know much about app.config files; I'm just trying to investigate this error. Any suggestions?

This is now fixed.
