The type '…' has no constructors defined

Question

I\'m noticing the compiler error The type \'...\' has no constructors defined generated when I erroneously attempt to instantiate a particlar class.

Answer 1

Also this error could be cause if you are compiling with Framework 4 or higher and embedding the Interop Types into your managed assembly. To get rid of this error you need to turn off (No embed) the Embedded Interop Types.

Instructions to turn off embedding:

1. On VS2010 Solution Explorer, right click on the Interop Reference that you are using.
2. Select Properties and look for Embed Interop Types
3. Change it from True to False
