Problem to generate file

Thanks.
I enable the Checkbox

Application\Assembly Information\Mark assembly COM-visible

and then re-generate the solution/project, but I still get no TLB file generated.

Make sure that your project is a 'Library' type:Then on the 'Compile' page, you will see an option for 'Register for COM interop':-saige-

Thanks. I don't know why the option is disabled (see the attached). Can you please refer to the project (attached in above), if possible?

The option is disabled because you are not building a library.

Previously, when re-building the solution, .TLB file would be generated. I don't know why now it would not. What is the reason to this? Thanks.

HuaMin,

I downloaded your project and unzipped it.  I cannot replicate your issue.  All of the required options are selected for the CSDemo project and it does build the tlb file.
Are you perhaps looking in the wrong folder?
