SqlGeography.STGeomFromText throw exception when creating Polygon

Question

During creating Polygon it throws execution. I am using library Microsoft.SqlServer.Types latest version 160.

polyText = "POLYGON ((

Created SqlGeography.Point it works fine without problem, only creating reading inserting polygon due it throws error.

Answer 1

I managed to resolve this exception by downgrading Microsoft.SqlServer.Types to version 14
