C# – Error: Unable to evaluate expression because the code is optimized

asp.netcmaster-pagesserver.transfer

I am getting an error in my asp.net app that reads

"Unable to evaluate expression because the code is optimized or a native frame is on top of the call stack."

protected void btnCustomerProfile_Click(object sender, EventArgs e)
{
    try
    {
        Server.Transfer("CustomerProfile.aspx");
    }
    catch (Exception ex)
    {
        Response.Write(ex.ToString());
    }
    finally
    { }
}

After searching SO, I see most of the similar posts involve response.redirect. My code is using server.transfer and my application is also using Master Pages.

How can I resolve this issue?

Update: For some reason, this error occurs is I use Response.Redirect as well. Unfortunately I cannot use Server.Execute, because Server.Execute calls the calling page towards the end.

You will get an error, but the code block below will trap it and you can get on with your life.

Try this:

using System.Threading.ThreadAbortException;

catch(ThreadAbortException ex)
{
    throw;
}
