Net Applications deployment and upgrade

[Gregory]

Hello,

 

I made a .NET Application with a deployment project. Everything work fine.

 

But now, i'm coding a new version of my application. After, i would deploy this new version to upgrade (or replace the old).

 

For the moment, the user must first uninstall the first version and after install the second.

 

Is there a solution for make a deployment project which upgrade (or replace) an old version of the application without uninstall it ??

 

Thank you

 

Sorry for my bad english

Yes, in the deployment project properties (that come up in the propertygrid when you select it) change the version to the new version number of your product, and say yes when it asks you if you want it to automatically change some keys. The installer will then automatically remove the previous version of your program when installing.
