After upgrading Managed Configuration to 3.x, it builds as an AddIn

[BarbaraSchneider2]

I upgraded a Managed Configuration from 2.x to 3.x using the "Pro Migrate Project" utility. In my config.daml, I specifiy the following:

 <Configuration>
   <ConfigurationManager className="ReliefConfigManager" />
 </Configuration>

However, when I buld my solution, an Add-In (....esriAddinX) is created instead of a configuration (....proConfigX). What am I missing?

I have found the solution: In the file manager, right click on <ProjectName>.csproj and open it in a text editor. At the bottom, just before the tag <Import Project..../>, add:

<PropertyGroup>
    <PackageType>Configuration</PackageType>
</PropertyGroup>
