I have a console application created with "ArcGIS Pro CoreHost application" template, if I open a .dwg file inside it with below function:
public static Geometry GetBoundary(string inProjectBoudaryPath, string cadFile)
{
try
{
var connectionPath = new FileSystemConnectionPath(new Uri(inProjectBoudaryPath),
FileSystemDatastoreType.Cad);
using (var dataStore = new FileSystemDatastore(connectionPath))
{
string fileName = Path.GetFileName(cadFile);
using (var dataset = dataStore.OpenDataset<CadDataset>(cadFile))
{
using (var polygonFeatCls = dataset.OpenDataset<FeatureClass>("Polygon"))
{
QueryFilter filter = new QueryFilter();
filter.WhereClause = $"Layer='Project Boundary'";
using (var cursor = polygonFeatCls.Search(null, false))
{
Geometry boudary = null;
while (cursor.MoveNext())
{
using (var feature = (Feature)cursor.Current)
{
if (GeometryEngine.Instance.IsSimpleAsFeature(feature.GetShape(), true))
{
if (boudary == null) boudary = feature.GetShape();
else boudary = GeometryEngine.Instance.Union(boudary, feature.GetShape());
}
else
{
var fixedGeometry = GeometryEngine.Instance.SimplifyAsFeature(feature.GetShape());
if (boudary == null) boudary = fixedGeometry;
else boudary = GeometryEngine.Instance.Union(boudary, fixedGeometry);
}
}
}
return Convert3DTo2D(boudary);
}
}
}
}
}
catch (Exception ex)
{
Console.Write($"Error when extract boudary from CAD, ex: {ex}");
return null;
}
return null;
}
public static Geometry Convert3DTo2D(Geometry inputGeo)
{
Console.WriteLine("Start to remove Z in feature");
if (inputGeo == null) return null;
SpatialReference hkProj = null;
using (SpatialReferenceBuilder srBuilder = new SpatialReferenceBuilder(2326))
{
// do something with the builder
hkProj = srBuilder.ToSpatialReference();
}
PolygonBuilderEx polygonBuilder = new PolygonBuilderEx(hkProj);
polygonBuilder.HasZ = false;
if (inputGeo.HasZ)
{
Polygon inPolygon = (Polygon)inputGeo;
for (int i = 0; i < inPolygon.PartCount; i++)
{
ReadOnlySegmentCollection segCol = inPolygon.Parts[i];
polygonBuilder.AddPart(segCol);
}
Console.WriteLine("Remove Z in feature successfully");
return polygonBuilder.ToGeometry();
}
else
{
Console.WriteLine("No Z found.");
return inputGeo;
}
}The program will not exit normally like below screenshot:
when debug in Visual studio 2022, it will display after finished:
And there is below error in output window of Visual Studio:
By the way, I use ArcGIS Pro 3.1 and related SDK for .Net and Visual Studio 2022.
Who can tell me if it is the bug of SDK?

I have tested your solution. One thing I have changed was path to dwg and dwg file name. It finished with code 0.

Could you tell me which Visual studio and SDK version you use?
My Visual studio 2022: 17.6.1
ArcGIS.CoreHost.dll: 13.1.0.41833
ArcGIS.Core.dll: 13.1.0.41833
