I have two solutions and they each have the same: Project guid

I needed a new solution that was little different from one I already had so
I copied the entire folder including the .sln file to a new folder and then
modified the files as needed.

So I now have two solutions and they each have the same guid [as in
Project("{guid )]

What are the ramifications of that?


Thanks

Not sure - as long as the projects are in different solutions, you're
probably fine. If they're in the same solution, that could cause problems
as the solution uses the guids.

You could always use uuidgen (command line) or guidgen (gui) and generate a
new guid. Then edit the project in a text editor and change the uuid. (I do
that all the time when using a previous project as a template for a new
project)

More importantly, what is the benefit of leaving it that way?

You could always use uuidgen ...
I didn't know if the guid was referenced someplace else (registry...)
If I understand the above I'd have to change in the project and in the
solution.

1)I don't have to do anything to leave it that way.
2)I can't introduce an error if I don't change it.

All you need to do is to search/replace the GUID in the solution + in each
of the projects within the solution.
 
It is not in the registry??

No. One of the "lessons learned" from COM was to try to stay away from
messing with the registry. Most things related to .NET do not use the
registry.

Even COM objects may be consumed without using the registry :-)
