Conflicting user.config due to non unique path between 2 addins

Hi, we are experiencing a problem described before in this thread: https://www.add-in-express.com/forum/read.php?a&FID=5&TID=13115&SHOWALL_1=0.

We have 2 add-in in our enterprise ecosystem. Addin 1. is using .NET built in configuration extensively. Addin 2. does not use user based configuration explicitly, however it does perform the Active Directory search, which for not know reason implicitly tries to read user.config . 



            DirectorySearcher oSearcher = new DirectorySearcher
            {
                Filter = "(&(objectClass=user)(legacyExchangeDN=" + legaxyExchangeDn + "))",
                SearchScope = SearchScope.Subtree
            };
            oSearcher.PropertiesToLoad.Add("sAMAccountName");
            oSearcher.PropertiesToLoad.Add("mail");

            var oResult = oSearcher.FindOne();
            return oResult.Properties["mail"][0].ToString();


We use above code to retrieve the mailbox of particular email. Exception gets triggered in oSearcher.FindOne(): 

System.Configuration.ConfigurationErrorsException: Configuration system failed to initialize ---> System.Configuration.ConfigurationErrorsException: Unrecognized configuration section userSettings. (C:UsersMyUserAppDataLocalMicrosoft_CorporationC__Program_Files_(x86)_Sw_Path_pzllr20oqrn1234b3lfbn4njpshdzry
.0.4859.1000user.config line 3)


This config however contains only the setting from the Addin 1.

The problem is that Addin 2. reads Addin 1. config file because of not enough unique config location and fails to understand it. Both addins assume that path:

C:\Users\MyUser\AppData\Local\Microsoft_Corporation\C__Program_Files_(x86)_Sw_Path_pzllr20oqrn1234b3lfbn4njpshdzry\15.0.4859.1000\user.config

is dedicated for them.

Do you have any ideas how to solve this conflict properly?

Thanks and best,
Pawel

Hello Pawel,

This isn't a problem of Add-in Express. It occurs in VB.NET projects only. You need to delete the .config file; this will end with recreating it.

To avoid this, your add-ins need to have different names and locate in separate folders.
