Hi.

I am trying to use Clickonce to deploy my project which contains a lot of report files (*.rpt) created with crystal reports.

Now I want to deploy these report files along with the project , I have added these files to the project & set the Build Action to Content.

When I try to set the publish status of these files to either Include or Data File , these files keeps dowloading each time a new update of the project is released even if the report files are not changed!!

Is there a way to download only the changed report files between updates!

ClickOnce uses file patching technique to avoid redundant downloading of application files. It compares the hash signatures of file to decide whether to download this file. The reason why your client download all files is you use Visual Studio to compile your application, it will generate new hash signatures for all files in your project. Try to compile it manually in Visual Studio 2005 Command Prompt, something like the following:
