Duplicate type with name 'Dynamics.Ax.Application."TableName"' in assembly in AX 2012

Hello All,

I have created 2 customize table(Header,Line).by using that i have created one AIF Web service(Inbound and Outbound).

Due to some reason i deleted Line table and immediately again I import that table.

But Due to that i facing error during CIL Generation.

"Duplicate type with name 'Dynamics.Ax.Application."TableName(Line)"' in assembly 'Dynamics.Ax.Application,

Version=6.2.158.0, Culture=neutral, PublicKeyToken=null'."

And my All AIF services are not working.

To Solve this issue,

I did  

1.Compilation.

2.Delete content Of XPPIL directory.

3.Full CIL Generation.

But Still i am facing same error during Full CIL Generation,

Please Help me to solve this issue,

Thanks

Anita.
