Duplicate type with name 'Dynamics.Ax.application.' in assembly 'Dynamics.Ax.application,

Question

I see following error when I compile CIL in Dynamics 2012 ax -

Duplicate type with name 'Dynamics.Ax.application.' in assembly 'Dynamics.Ax.application, version=6.0.947.280, culture...

I tried

Delete class from AOT
Delete XppIL directory (c:\Program Files\Microsoft Dynamics AX\60\Server\InstanceName\bin)
Restart AOS
Run CIL compile

What else I can try ?

Did you try to compile the entire application? – Feb 15 '13 at 17:58 — , Feb 15 '13 at 17:58

The following should resolve the problem:

Full compile AX
Stop the AOS
Truncate the SysXPPAssembly table in SQL (the table is used to contain the assemblies and to share between multiple AOS instances)
Delete the DLL and netmodule files in your AOS's bin\xppIL directory
Restart the AOS
Perform full CIL generation

The Review Nazies rejected my attempt to correct the table name; it should be [SysXppAssembly](http://msdn.microsoft.com/en-us/library/sysxppassembly.aspx). – Martin Olsen Mar 21 '13 at 17:21

This is what worked forme (this time).

Stop the AOS
Delete/Move XppIL directory (c:\Program Files\Microsoft Dynamics AX\60\Server\InstanceName\bin)
Restart AOS
Run Full CIL compile
Infolog displays list of errors returned by Full CIL.
Natively compile offending classes/projects, code corrections my be necessary.
Perform another Full CIL
