Remote event receiver install via PNP problem

Hi Bert,

i just checked it is not in the manifest but in a provisioning classs the code looks like this:

   AuthenticationManager authenticationManager = new AuthenticationManager();
            using (ClientContext workPackageContext = authenticationManager.GetSharePointOnlineAuthenticatedContextTenant($"{Info.ProjectUrl}/{workPackage.Url}", Info.UserName, Info.UserPassWord.ToSecureString()))
            {
                Guid sideloadingFeature = new Guid("AE3A1339-61F5-4f8f-81A7-ABD2DA956A7D");

                string path =  Path.GetFullPath("Resources/App/DocNumber.app");
                Site site = workPackageContext.Site;
                Web web = workPackageContext.Web;
                try
                {
                    // Make sure we have side loading enabled. 
                    // Using PnP Nuget package extensions.
                    site.ActivateFeature(sideloadingFeature);
                    try
                    {
                                      
                        // Load .app file and install that to site
                        var appstream = System.IO.File.OpenRead(path);
                   
                        AppInstance app = web.LoadAndInstallApp(appstream);
                        workPackageContext.Load(app);
                        workPackageContext.ExecuteQuery();
                    }
                    catch (Exception exp)
                    {
                        TraceHelper.WriteErrorToListener("AddAppToSite Adding", exp.Message);
                    }
                    // Disable side loading feature using 
                    // PnP Nuget package extensions. 
                    site.DeactivateFeature(sideloadingFeature);
                }
                catch (Exception ex)
                {

                    TraceHelper.WriteErrorToListener("AddAppToSite", ex.Message);
                }
            }
        }

But it states in the error that the app is already installed.

The app is installed on tenant level  just to set the permisions. that i do not have to check the trust everytime. But since it is on tenant nivo i still need to install it in order to get it to work in the site...

I think that is why my event receiver does not register to a list as it is pushed from tenant level and not from a site level.

Hope you understand what i mean.

Any help is welcome.
