Hi,  
We are upgrading from MapSuiteCore (9.0.0.0) to ThinkGeo.Core (12.3.2).

In our code we are using Feature.MakeValid() function which is not available in ThinkGeo.Core (12.3.2).

Can you please suggest any alternate way?

Please find below code for the reference:

Feature editFeature = new Feature(editFeaturesWkt);  
BaseShape editBaseShape = editFeature.MakeValid().GetShape();

Thanks,  
We have some discuss about this one. The main reason is that Microsoft.SqlServer.Types library we are using in the mapsuite 10 not support .net core
