Answer 1

for guys still looking into this issue one thing u need to know is there are different GACutils out there , so u need to make sure that ur using correct GACUTIL to deploy the DLL to correct GAC

for eg: if my dll was complied in 3.5 .net framework and my OS version was 64 bit windows it would be in below location

C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\Bin\x64

Struggled for 4 stupid days to figure this out

Answer 2

For assemblies not in GAC, and which are referred in the build, sometimes this error also happens if the platform target does not match. So match the assembly platform type to the one where it is being used.

Answer 3

Please try to unreference the DLL then re reference it again and rebuild you project. Also Check to ensure that the version matchs what is in the project web config
