Unable to Add C++ Dll in C# project

Tech-Archive recommends: Fix windows errors by optimizing your registry

Hi,

I am trying to add a dll (created as a VC++ project) in VS2005 to a C#
project for a Smart Device.
Each time I try to add reference, an error message is thrown up
stating "Unable to add Dll".

Following are the steps I followed:

1. Add New Project -> VC++ -> Smart Device -> Win32 Smart Device
Project -> Dll
2. Build project (Test.dll). (empty dll project for testing)
3. In my C# project, Add reference -> Test.dll

At this point it throws up an error stating "A reference to Test.dll
could not be added".

I tried registering the Dll with "regasm" but even that threw an error
stating "Test.dll is not a valid .Net assembly"

Is there something wrong with the procedure followed by me or is it
some other issue (like an installation issue)?

Thanks in advance,
Treadstone
