Replacing dll to a newer version

Question

I have a Caliburn.Micro application with many projects. Several projects refer to the same dll in a separate folder. Now I needed to replace that dll with a newer version. I

I think you're using Visual Studio. First of all, check in the properties of all that FileHelpers referenced if the Specific Version is set to False (if not, do it). Try to clean and build back.

If the problem persist, in the app.config of your solution, in the configuration section, add

<runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
        <dependentAssembly>
            <assemblyIdentity name="FileHelper" publicKeyToken="3e0c08d59cc3d657" culture="neutral"/>
            <bindingRedirect oldVersion="0.0.0.0-2.0.0.0" newVersion="2.0.0.0"/>
        </dependentAssembly>
    </assemblyBinding>
</runtime>

In this way you should be able to force the used version to the new one.

My guess is that you need to add references to other assemblies.

Please attach the text of the csproj to show the reference to the dll you updated.

Assemblies can reference other assemblies that aren't required to compile but are required at runtime. You need to determine if FileHelpers is the assembly you explicitly referenced. Please see the following links on how to use Fusion Log Viewer. It will give you information on where it is looking to find assemblies.
