I got a program to backup the database in SQL with C#.I want to backup SQL versions 2014 and above.
I have the following section in web.config:

 <dependentAssembly>
    <assemblyIdentity name="Microsoft.SqlServer.SqlClrProvider" publicKeyToken="89845dcd8080cc91" culture="neutral" />
    <bindingRedirect oldVersion="0.0.0.0-13.100.0.0" newVersion="13.100.0.0" />
  </dependentAssembly>

In bin, I have the following DLL:

Previously, it worked without any problem, but now it gives the following message during the backup:

Could not load file or assembly ‘Microsoft.SqlServer.SqlClrProvider, Version=15.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91′ or one of its dependencies. The located assembly’s manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

How can my problem be solved?
