In my application we have COM component, .Net components and there are tlbs for which the interop gets generated. These tlbs get register at the time of installation. We need to make it application to run registration free. I am able to run it for COM components and .net components.
Now I need to make the tlbs also registration free, anyone knows how to achieve it.

Thanks in advance.

If you have .NET 4.0, it has the ability to embedded COM interop type libraries.  If you don't have it, then I have no idea how you would achieve that.

Hi TheLearnedOne,
Thanks for your reply.
I want to know how side by side configuration works for interop?

Can you give me an example of what you mean by "side-by-side" with COM?  Are you talking about something like Word 2007 and Word 2010?  These are distinct type libraries, and each one would have a different reference in a .NET project, and would be embedded differently.  Embedding interop type libraries within a .NET assembly is not 100% perfect.  There are times when you are suggested to turn off embedded interop references.

COM components gets registered in system registry. In side by side configuration we remove the dependency on registry by adding all the details in manifest file. Basically side by side configuration is used to overcome the problem of DLL hell.

With embedded COM interop, the type libraries are loaded into the assembly, and that removes the need for registration in the system registry.  Therefore, you should be able to use any COM component that can be embedded.

There are references to side-by-side and embedded COM.

I have added my tlb details in my application manifest (i.e. app_name.exe.manifest) as follows.

 <file name="tlb_name.tlb">
    <typelib tlbid="{D897017D-EC6A-4E42-8D89-245BBCDB446F}" version="1.0" helpdir="1.0 Type Library"/>
  </file>
  <comInterfaceExternalProxyStub name="InterfaceName" iid="{FB0FF818-0FF9-67AB-BFAE-35CB56E10851}" tlbid="{D897017D-EC6A-4E42-8D89-245BBCDB446F}" proxyStubClsid32="{00020424-0000-0000-C000-000000000046}"></comInterfaceExternalProxyStub>

If I unregister my tlb, my application is working.

How is that any different from embedding a COM reference in the assembly?  Are you saying that you don't have 4.0?  COM references in 4.0 are added with Embedded COM Interop = true by default.
