Need to know about [assembly: AssemblyMetadata("SquirrelAwareVersion", "1")]

[SunnySv72]

Hi @anaisbetts, I am trying to implement the Squirrel.Windows in my window forms application. As mentioned in document for customize squirrel events, I did code. i.e.

using (var mgr = new UpdateManager(ProductInfo.Instance.UpdaterURL)) 
{
          SquirrelAwareApp.HandleEvents(
                 onInitialInstall: v => mgr.CreateShortcutForThisExe(),
                 onAppUpdate: v =>
                 {
                     //logic
                 },
                 onAppUninstall: v =>
                 {
                     //logic
                     mgr.RemoveShortcutForThisExe();
                 });
}

it works fine however, I have some queries i.e.

• According to the document, we need to add [assembly: AssemblyMetadata("SquirrelAwareVersion", "1")] line in AssemblyInfo.cs. But I am able to run my code even without this line and all seems working fine. Therefore is it safe if I don't include this line in assembly or it will cause any issue which I didn't get yet.

• If it is mandatory to add this line then I would like to know about the way to adding this line from MSBuild target as I am creating the Assemblyinfo.cs dynamically through MSbuild command.

Looking forward for your quick response.

Thanks.

Perhaps this might help. If not, please excuse my comment on this issue. This might be the relevant code to your question here. From what I can gather (from the code and from my own experience with Squirrel), if no apps are marked as SquirrelAware the installer / updater runs them all. See this line and below.

We used the same approach as you in our production app, but later had to mark our main app as SquirrelAware once the software grew and we had two executables in the installer (as we then all of a sudden had both apps run automatically on install instead of the one we wanted).

However, I am not certain about the non-standard install logic running (as in your code above) without being SquirrelAware (especially onAppUpdate). It seems from the code that non-SquirrelAware apps aren't run by the UpdateManager with the argument "--squirrel-updated" and therefore wouldn't run the onAppUpdate lambda, but I could be mistaken.
