There is a function MakeValid() in v10 which makes a feature valid. but I can’t find it in v12.  
Can anyone suggest an idea?

(I have an alternative solution which used SQLGeomtery)

Thanks Mahdi,  
Mapsuite 12 doesn’t support MakeValid. The reason is that Microsoft.SqlServer.Types libary we are using in the mapsuite 10 not support .net core. You are correct the alternative solution is using SQLGeomtery.

Thanks
