Spatial data operations

Question

Hello,

I have to migrate some routines written in VBNET in WPF environment on AZURE (webapi net core).

In these routines spatial operations such as union, intersection, etc. take place.

here is an example:

Private Sub example(ByVal sender As System.Object, ByVal e As System.EventArgs)  
        Dim myGeom1 As SqlGeometry = SqlGeometry.STGeomFromText(New SqlString("POLYGON((0 10, 10 10, 10 0, 0 0, 0 10))"), 0)  
        Dim myGeom2 As SqlGeometry = SqlGeometry.STGeomFromText(New SqlString("POLYGON((0 0, 4 0, 4 4, 0 4, 0 0))"), 0)  
        'Dim myGeom2 As SqlGeometry = SqlGeometry.STGeomFromText(New SqlString("POLYGON((1 -1, 1 5, 3 5, 3 -1, 1 -1))"), 0)  
        Dim myGeom3 As SqlGeometry = SqlGeometry.STGeomFromText(New SqlString("POLYGON((5 0, 8 0, 8 1, 5 1, 5 0))"), 0)  
        MsgBox(myGeom1.STArea)  
        MsgBox(myGeom2.STArea)  
        MsgBox(myGeom3.STArea)  
  
        Dim union As SqlGeometry = myGeom2.STUnion(myGeom3)  
        MsgBox(union.STArea)  
        Dim intersect As SqlGeometry = myGeom1.STIntersection(union)  
        MsgBox(intersect.STArea)  
        Dim difference As SqlGeometry = myGeom1.STSymDifference(union)  
        MsgBox(difference.STArea)  
    End Sub  

I wanted to migrate to use Microsoft.Spatial but it does not contain methods to recover the area for example microsoft.spatial.spatialoperations

more similar methods can be found in the System.Data.Entity.Spatial system.data.spatial.dbspatialservices.getarea

I read that Microsoft.Spatials will be more supported but at the moment they don't solve the problems for me.

how do you recommend to proceed?

Thanks
