SitecoreContext throwing error after Sitecore upgrade

Question

I upgraded my dev instance from Sitecore 8.2 to Sitecore 9.3.

My upgrade was successful but I am getting errors when I am trying to access my page.

In our solution for getting the current page, we are using SitecoreContext.

Here my code:

var currentPage = SitecoreContext.GetCurrentItem<BasePage>();

and by using this code on the page I am getting the error, shown in below screenshot

We are using the following glass mapper version

<package id="Glass.Mapper.Sc.93.Core" version="5.8.171" targetFramework="net48" />
<package id="Glass.Mapper.Sc.93.Mvc" version="5.8.171" targetFramework="net48" />

Answer 1

As I can see you are using GlassMapper 5 version and in GlassMapper 5 version SitecoreContext, GlassView, GlassController are obsolete. On behalf of SitecoreContext you can Use either IRequestContext, IMvcContext or IWebFormsContext.

Or you can use SitecoreContext as well, by initializing it first then use it.

var objSitecoreContext = new SitecoreContext();
var currentPage = objSitecoreContext.GetCurrentItem<BasePage>();

It will work for you.

Answer 2

GlassMapper functionality was removed from 5.x SitecoreContext. That's why you cannot call sitecoreContext.GetItem anymore. According to Glass Mapper documenation (link below):

sitecoreContext.GetItem 

should be replaced with

mvcContext.SitecoreService.GetItem
