Invoking a C#.NET dll from an external application using COM Objects

[shadowcat]

Hi,

I need to invoke a C#.NET dll that I developed in Siebel. For this I added the assemblies to GAC and then used regasm with the tlb option. Then in Siebel 7.7 I created a COM Object for this and invoked its methods successfully.

However when I try the same thing in Siebel 8.0, I am able to create the COM object, but not able to invoke its methods. The Siebel application crashes when I try to invoke its methods. I know this is may be a Siebel problem, but if any of you thinks I can fix this by using a different regasm option or something in the .NET side of things please let me know. I have no clue why this is happening.

Any pointers here would be appreciated!

Thank you,
SC

Just incase you need the commands I executed:

gacutil /i D:\PS\POLICYSERVICE.SCINTERFACE.dll
gacutil /i D:\PS\POLICYSERVICE.SCCREATOR.dll
gacutil /i D:\PS\POLICYSERVICE.PCINTERFACE.dll
gacutil /i D:\PS\POLICYSERVICE.PCS.dll
gacutil /i D:\PS\POLICYSERVICE.PCCREATOR.dll
gacutil /i D:\PS\POLICYSERVICE.SCS.dll
gacutil /i D:\PS\POLICYSERVICE.DATATYPES.dll
gacutil /i D:\PS\PolicyInfo.dll
gacutil /i D:\PS\POLICYSERVICE.SCS.XmlSerializers.dll
gacutil /i D:\PS\UtilityClass.dll

regasm "D:\PS\POLICYSERVICE.DATATYPES.dll" /tlb:POLICYSERVICE.DATATYPES.tlb
regasm "D:\PS\PolicyInfo.dll" /tlb:PolicyInfo.tlb
[The above 2 dlls are those I need in Siebel]

I got success messages [Types registered successfully..Assemblies exported..]

Inspite of all this the methods of the COM object that I create remain inaccessible from Siebel 8.0 while being accessible from Siebel 7.7.

Hi,
I'm having the very same problem, with Siebel 8.0.0.8. I wonder, did you find any solution?

Thanks,
