Could not load type ServerSideViewStateAdapter App_Browser

Question

Improving the performance of ASP.Net Webforms I tried a method which throw an error of Could not load type 'ServerSideViewStateAdapter'.

 

In my App_Code folder I have created a class with the same name.

using System;
using System.Web.UI;
using System.Web.UI.Adapters;
namespace MyProject.App_Code {
public class ServerSideViewStateAdapter : PageAdapter
{ public override PageStatePersister GetStatePersister()
{
// return base.GetStatePersister();
return new SessionPageStatePersister(this.Page);
}
}
}

and in App_Browseers I have created a file with the name of ViewStateAdapter.browser in which I'm getting an error on the

<browsers>
<browser refID="Default">
<controlAdapters>
<adapter controlType="System.Web.UI.Page" adapterType="ServerSideViewStateAdapter" />
</controlAdapters>
</browser>
</browsers>

The Error says: Parser Error Message: Could not load type 'ServerSideViewStateAdapter'.

 

I'm using VS 2013.

 

Kindly guide me regarding this error.

Thank you.
