I've seen this issue before. Looking at the Nuget documentation [^] for iTextSharp shows several versions. If you have 2 or more projects using that package, you need to ensure they all have the same version. If they have different versions, you'll get this error.

In VS2015 Solution Explorer, right click each project that uses iTextSharp and select "Manage Nuget Packages". The window that comes up will show installed packages. Click on iTextSharp and the right pane will be "Version" with a drop down next to it. Ensure that all projects are targeting the same version of the Nuget package. Once they are all the same version, re-compile and test, the error will go away.

Check if itextsharp DLL with version '5.5.0.0' is present in your reference directory in solution explorer. If it is present then you need to Clean up your existing solution, remove its reference and then add it again, finally rebuilt it.
I think it will resolve issue

i am using vs 2010 with C# in windows application. How to clean it have seen commands but that was web related but i need windows applications.
itextSharp version is 4.1.2.0 in references folder.
But I checked my appconfig and its showing Version 5.5.0.0
<runtime>
<assemblybinding xmlns="urn:schemas-microsoft-com:asm.v1">
<dependentassembly>
<assemblyidentity name="itextsharp" publickeytoken="8354AE6D2174DDCA" culture="neutral">
<bindingredirect oldversion="0.0.0.0-5.5.0.0" newversion="">
