Hello,

I am attempting to migrate some of my .net applications from vs2008 to
vs2010. Which also includes moving to .net 4.0 from .net 3.5. One of
my applications is a COM SmartTag. I have found that when I change the
smart tag dll to use .net 4.0 instead of .net 3.5 it no longer loads.
When I run Fusion Log Viewer I get the following error:

ERR: Error extracting manifest import from file (hr = 0x8013101b).
ERR: Setup failed with hr = 0x8013101b.
ERR: Failed to complete setup of assembly (hr = 0x8013101b). Probing
terminated.

I think 0x8013101b means a mismatch in the runtime, which would make
sense as switching back to .net 3.5 fixes the issue.

Anyone have any ideas how to get smarttags working with .net 4.0?

Cheers

Chris

I have the same problem but with a .NET Windows Forms control hosted in IE.

I was using .NET 3.5 and everything was working fine. Once updated to .NET
4.0 the control start failing to load and Fusion Log give me the exact error
messages and codes.

Did you find a solution for your problem?
