ArcGIS Pro 3.0 - System.Data.SqlClient.dll reference assembly

MadsHoumann

The ArcGIS Pro 3.0 install include System.Data.SqlClient.dll reference assembly.
As far as I can see, the actual implementation assemblies are not installed.

Our add-in needs System.Data.SqlClient, but since the ArcGIS Pro 3.0 installed version: 'C:\Program Files\ArcGIS\Pro\bin\System.Data.SqlClient.dll' is just the reference assembly it doesn't work.
And this version is loaded even when the correct implementation assembly is included in the add-in.

Am I missing something here? or is it a bug in the ArcGIS Pro 3.0 install?

You can look at this example (from community samples) which is using the Microsoft.Data.SqlClient NuGet in its plug-in project: ProSqlExpressReader solution more specifically the 'Microsoft.Data.SqlClient' package reference in this project: arcgis-pro-sdk-community-samples/ProSqlExpressDb.csproj at master · Esri/arcgis-pro-sdk-community-samples (github.com)

The real question is WHY is System.Data.SqlClient.dll event included in the ArcGIS Pro 3.0 install package, and why is it located at C:\Program Files\ArcGIS\Pro\bin?

ArcGIS Pro is built on .Net Framework 6.0.5 which does not support the use of System.Data.SqlClient. All Add-ins should be rebuilt to use Microsoft.Data.SqlClient and WebView 2 (vs. WebBrowser).

Thanks,
I guess switching to Microsoft.Data.SqlClient will be an OK option for us.
