  Changes in web.config when .net framework is upgraded to 4.0 from 3.5

  Jan 12, 2018 08:32 AM|hardeshis|LINK

  I have web application which was originally written in .net framework 3.5. I have changed .net framework to 4.0.

  I noticed some changes in web.config file. 

  Under 3.5 I had  <runtime /> section in web.config file. But when I changed to .net framework to 4.0, I can not see this section in web.config file.

  <runtime>
  <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
  <dependentAssembly>
  <assemblyIdentity name="System.Web.Extensions" publicKeyToken="31bf3856ad364e35"/>
  <bindingRedirect oldVersion="1.0.0.0-1.1.0.0" newVersion="3.5.0.0"/>
  </dependentAssembly>
  <dependentAssembly>
  <assemblyIdentity name="System.Web.Extensions.Design" publicKeyToken="31bf3856ad364e35"/>
  <bindingRedirect oldVersion="1.0.0.0-1.1.0.0" newVersion="3.5.0.0"/>
  </dependentAssembly>
  </assemblyBinding>
  </runtime>            // This section not present in web.config under 4.0 framework.

  I had under 3.5 framework,

  <pages>
  <controls>
  <add tagPrefix="asp" namespace="System.Web.UI" assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
  <add tagPrefix="asp" namespace="System.Web.UI.WebControls" assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
  </controls>
  </pages>

  But under 4.0 I have following,

  <pages controlRenderingCompatibilityVersion="3.5" clientIDMode="AutoID" />

  -----------

  Wanted to know about these changes. Do I need to add <runtime /> section and change <pages /> section like 3.5 framework?

  Hi,

  Seems quite standard so no. Does it work ? Options were added over time to the web.config file and in 4.0 it was moved again to the general machine.config file so that you can have a simpler web.config file.

  The options you see is to generate the same HTML markup and client ids in case you would have code depending on that...

  Edit: see https://msdn.microsoft.com/en-us/library/s57a598e.aspx#aspnet_core_services and "Web.config File Refactoring".

  Yes without <runtime> section and <pages> section as per 4.0 it's working fine.
