Has anyone successfully used an app.config file with your Add-In? I have added an app.config file to my visual studio pro SDK project and I’m trying to retrieve a connection string from it. The retrieval code always returns null. I don’t know if that’s because it is a UserControl or running inside ArcGIS Pro or what. Any thoughts? Is there a better place to store the connection string?
Visual Studio 2017, .Net Framework 4.6.1, ArcGIS Pro SDK 2.1, SQL Server
<?xml version="1.0" encoding="utf-8" ?>
<add name="my_conn" connectionString="Data Source=xx.xx.xx.xxx;Initial Catalog=some_db;User ID=xxx;Password=yyy" />
// Assume failure.
string returnValue = null;
// Look for the name in the connectionStrings section.
ConnectionStringSettings settings = ConfigurationManager.ConnectionStrings["my_conn"];
// If found, return the connection string.
if (settings != null)
returnValue = settings.ConnectionString;
