In vb.net we have a version control in there we have 1.1.2.3 this is the old version of Dll we have change only the 1.1.2.4 for the New dll which is compablitly of the ealry version.

One need to specify "bindingRedirect" in the config file.

e.g.

<configuration>

<runtime>

<assemblyBinding smlns="urn:schema-microsoft-com:asm.v1">

<dependentAssembly>

<assemblyIdentity name="Test" publickeyToken="b035c4774706cc72" culture="neutral">

<bindingRedirect oldVersion="1.1.2.4">

newVersion="1.1.2.3"/>

</dependentAssembly>

</assemblyBinding>

</runtime>

</configuration>
