Lately I got a warning message each time I opened the DelftShell solution file.
"The .. project has been customized and could present a security risk by executing custom build steps ...."
I had to choose wether I should load the project for browsing or normally.
Because it bothered me a lot I started to search for a way to get rid of this message. It seems that the reference to DelftShell.targets is seen as an unsafe import.
By adding a registry string value in the following registry location I could get rid of these messages:
HKLM\SOFTWARE\Microsoft\VisualStudio\9.0\MSBuild\SafeImports
string key properties:
name: delftShellTargets
value: d:\src\delft-tools\src\build\DelftShell.targets (path to DelftShell.targets file)
