NOTE: I am answering my own question in the event it helps others in the future.
I'm getting the error:
The assembly "C:\XYZ.dll" could not be converted to a type library. Type library exporter encountered an error while processing 'XYZ'. Error: Element not found.
Here is the code that causes the problem:
[Guid("7a4e9867-96a7-43f0-9492-0327b9053853"),
ClassInterface(ClassInterfaceType.None)]
public class TimeSeriesPoint
{
public string Date { get; set; }
public float Value { get; set; }
}
[Guid("7a4e9867-96a7-43f0-9492-0327b9053853"),
InterfaceType(ComInterfaceType.InterfaceIsDual)]
public interface IDataHelper
{
//RCOMServerLib.IStatConnector Connector { set; }
string Text { set; }
void DoCallback();
I was using the same GUID from the AssemblyInfo file:
[assembly: Guid("7a4e9867-96a7-43f0-9492-0327b9053853")]
You need to use unique GUIDs to resolve the error:
[Guid("C25D485B-F7DE-4F1C-99FE-FFAF5A219B77"),
ClassInterface(ClassInterfaceType.None)]
public class TimeSeriesPoint
{
public string Date { get; set; }
public float Value { get; set; }
}
[Guid("FA6F70DD-CDD0-4FF3-94BA-E2B94E68321D"),
InterfaceType(ComInterfaceType.InterfaceIsDual)]
public interface IDataHelper
{
//RCOMServerLib.IStatConnector Connector { set; }
string Text { set; }
void DoCallback();
To get unique GUIDs in Visual Studio click Tools Menu > Create GUID > select the 4th option Registry Format > Copy:
