How to get rid of .suo files?

Question

We have people with a mix of VS 2010 SP1 and VS2012 working with TFS 2010. 

A few existing projects have .suo files and according to http://msdn.microsoft.com/en-us/library/vstudio/hh266747.aspx, suo is not supported for round-tripping between the two VS versions. 

http://msdn.microsoft.com/en-us/library/bb165909(v=vs.80).aspx has a very brief description of the .suo file but does not explain when or why it is needed.  Is there a way to get rid of the .suo file in existing solutions so as to make them workable across VS 2010 and VS 2012?

Thanks.

Answer 1

Just delete those.

It contains information about what settings current user has selected for his/hers VS working environment, nothing that cannot be recovered/recreated. Other users won't use this same .suo file anyhow, as it is not stored in TFS (or it should not be there by default).

Answer 2

Ilpo, thanks.  Before I start deleting this file, would anyone or Microsoft like to second this recommendation?  Thanks.

Answer 3

Hi K.Kong,

Thanks for your post and sorry for the delayed response!

As Ilpo said, the .suo file is a user-specific file, and cannot be shared between developers. The .sln file can be shared between developers on a development team.

So based on my understanding,  you can delete the .suo files.
