Exported typelib not getting updated C# project

Rahul M

I am exporting DLL to a typelib(.tlb) using

"C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\RegAsm.exe" $(TargetDir)Project.dll /tlb:com.Project.tlb /codebase

It is getting registered succesfully.I look in typelib using liewiewer,all method declaration was proper.

But if I add any new method in DLL project and rebuild/clean .tlb file seems to be not getting updated with newely added methods.

Please let me know what I am missing?

Are you sure you are using the updated type library? It might being put someplace other than where you expect.

First unregister the old dll using
```
REGASM /u MyAssembly.dll 
```
The thing you want to watch out for (and the real reason for this post) is that if you used the /tlb option to register a type library, you need to make sure you include the /tlb option when unregistering. If you don't, only the COM object is unregistered, but the type library is still registered. And you can't unregister the type library by itself.
```
REGASM /u MyAssembly.dll /tlb:MyAssembly.tlb
```
Then again register the new dll using regasm.

if the above does not work, can you try putting the dll in a different location and try registering from there??

Remove the exported code build the project. After it throws you build error again export the dll using typelib. It should work :).

I know it sounds funny but I have faced this problem and I feel its cause Microsoft picks up stuff from Temp files. A build error clears the cached stuff and hoping it will help you fix.
