Dears,
Kindly help me with this issue, why I'm getting these errors, I've cleaned the project, rebuilt it, check the references, assemblies in aspx file and web config, nothing duplicated, am I missing something!
VS 2019
Hello,
From the screenshots that you have provided I couldn’t find any version mismatch or duplicate assemblies. What I could suggest you is checking the contents of the Bin folder of the project for any version mismatch or duplicate DLLs and remove them. After that rebuild and run the project.
Please let me know if this has resolved your issue or if we should look for an alternative solution.
Looking forward to hearing from you.
Regards, Ivan Kitanov
OMG, thanks Ivan as usual for your kind support, I found the duplicated dll file in the bin folder. thank you so much.
