  error CS1752: Interop type 'Some.Type' cannot be embedded
  Symptom:
  When compiling the following error is generated:
  error CS1752: Interop type 'Some.Type' cannot be embedded. Use the applicable interface instead.
  where
  Some.Type[] is the COM type you are trying
  to use.
  This may also be accompanied with the error:".
  Cause:.)
  Possible Remedies:
  - Change the .NET framework to a framework prior to .NET 4.
  This probably is not an ideal solution.
  - Tell Visual Studio not to embed the interop types for that assembly.
  To do this in Visual Studio 2010:
  - Identify the namespace: In the code where you have the error, right click on the type and select "Go To Definition". From this you should be able to identify the name of the namespace which contains the type - this is the name of the reference you will use below.
  - In the Solution Explorer, expand the list of References for the project.
  If you are using VB rather than C# then you will need to look in the project settings for the list of references.
  - Right click the the reference that you identified above in step 1, and select "Properties".
  - In the reference's properties change the property "Embed Interop Types" from "True" to "False"..
