Hi community,
I have an issue while updating Creatio from the 7.18.0 version to the 7.18.1 version. The base version I started from was the 7.17.4 and everything worked as expected for the update to the 7.18.0 update. When I try to update the version from the 7.18.0 to the 7.18.1 I have some problems, please take look at the screenshot below :

[11:10:15] Autogenerated\Src\ODataEntities\DuplicatesHistory.BackReferences.Deduplication.cs(21,52): error CS0234: The type or namespace name 'DuplicatesHistory' does not exist in the namespace 'Terrasoft.Configuration' (are you missing an assembly reference?) [D:\Creatio\QUAL\Terrasoft.WebApp\Terrasoft.Configuration\Terrasoft.Configuration.ODataEntities.csproj]
This is an example of an error. I get this error for every single file under the "Autogenerated\Src\ODataEntities\" folder. I tried to give all the rights to the IIS user but it didn't changed anything.
Any advise on how to solve this ? Before the update I regenerated the schema code sources and compiled the 7.18.0 version and everything worked as expected.
Thanks for you help !
