EncExchangeSet.LoadAsync() Internal Error: Failed to load ENC exchange set

Question

When I try to load an EncExchangeSet object, I get the following error:

Esri.ArcGISRuntime.ArcGISRuntimeException: Internal Error: Failed to load ENC exchange set

I use the same code provided in the sample codes section (https://developers.arcgis.com/net/wpf/sample-code/add-enc-exchange-set/), and I feed the EncExchangeSet constructor with a valid path to a "CATALOG.031" file.

I get this error in the loading step:

await myEncExchangeSet.LoadAsync();

What may cause this error and what should I do to fix this?

Hello,

These charts are Inland ENC (IENC) and apparently not supported by ArcGIS Runtime.

I was able to view them with an older version (100.2).

Use this demo app: https://github.com/Esri/arcgis-runtime-demos-dotnet/tree/main/src/HydrographicsSample

However, ArcGIS Runtime versions after 100.2 will not load IENC data.

line, I get this error:

Esri.ArcGISRuntime.ArcGISRuntimeException: Internal Error: Failed to load ENC exchange set

Hello, are you able to share the CATALOG.031 file?

Can you paste the code that loads the CATALOG.031 file?
