In my class library, I am referencing DLL’s from my website’s bin folder. Sometimes the DLL’s in the bin folders get updated, then I get the error of:

    Could not load file or assembly 'MyAssembly.Sub, Version=3.7.2096.3, Culture=neutral,
 PublicKeyToken=dfeaee3f6978ac79' or one of its dependencies. The located assembly's
 manifest definition does not match the assembly reference.
(Exception from HRESULT: 0x80131040)

How do I disregard the version number so that the DLL’s can get updated without the application looking for a specific version number?? Can’t just look for the namespace only?

This is what the reference looks like in my .csproj file:

<Reference Include="MyAssembly.Sub, Version=3.7.2057.3, Culture=neutral, PublicKeyToken=dfeaee3f6978ac79, processorArchitecture=MSIL">
  <SpecificVersion>False</SpecificVersion>
  <HintPath>..\..\SomeWebsite\bin\MyAssembly.Sub.dll</HintPath>
  <Private>False</Private>
</Reference>

    You can use an assembly binding redirection specified in web.config. I’m not sure whether you can say “always use latest”, but you can specify a particular version. When you update the version you’re deploying, just update web.config as well.

    For more on assembly binding redirection, read the MSDN article about it.
