Describe the bug Builds in visual studio 2019 but not using "dotnet build" or in Linux container

ERROR: The type provider 'FSharp.Data.Sql.SqlTypeProvider' reported an error: Could not load type 'System.Data.SqlClient.SqlConnection' from assembly 'System.Data.SqlClient, Version=4.6.1.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'.

To Reproduce Steps to reproduce the behavior:

1. create a new .net core 3.1 F# console project with SQL provider in it and connect to a SQL server database
2. build using cli dotnet build

Expected behavior builds correctly

Try adding a reference to System.Data in your project.

@Thorium do you mean System.Data.Common or System.Data.SqlClient. I have install both and it still has the same error

I guess this is duplicate of #580

There has been some issues with System.Data.SqlClient on .Net Core 3.1, so there is the dynamic version: https://github.com/fsprojects/SQLProvider/issues/645#issuecomment-639163535
