Description

Using the following code to return a single integer without a class defined - just an int.

using (var conn = new SqlConnection(connStr)) { ret = await conn.ExecuteScalarAsync<int>( "App.PointBalanceByID_Get", param: new { MyID }, commandType: CommandType.StoredProcedure); }

Returns the following error: System.IO.FileNotFoundException: Could not load file or assembly 'System.Data.SqlClient, Version=4.6.1.5, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'. The system cannot find the file specified.

If I revert System.Data.SqlClient back to4.6.1 it works but the current version 4.8.5.

All other calls on 4.8.5 where I am mapping to a custom class seem to work fine.

Research direction

Start by reproducing the shown ExecuteScalarAsync call with System.Data.SqlClient 4.8.5 and compare it with version 4.6.1. Investigate why this scalar path reports the missing assembly while mapped-class calls work, then verify that the call succeeds without FileNotFoundException on the current package version.
