try to clean build and publish again – Neelam
How does your publish process look like? Do you use the publish dialog? – citronas
I'm publishing right from Visual Studio, just right click on the Project and click publish and follow the steps. Before that I was publishing directly on the server (copy/paste). – Slobodan Jovanovski
I don't know if I understand you correctly. I hope you are talking about copy/paste the published files and not the source code. Check if your remote IIS server has all the required ASP.Net and .Net framework versions installed. Also check the app pool version numbers – citronas
the Framework version on my IIS web server is 4.0 and the ASP.Net is 4.0 but I can't find the app pool version. And Yes by Copy/Paste I mean copying the published files not the source code. Could it be that my IIS web server is supporting ASP.Net web sites but not ASP.Net web applications?? Because on my localhost I had to convert my website to web application. – Slobodan Jovanovski

I received this error directly after moving from VS 2015 to VS 2019. The Project was fully functional before.

My issue was related to bad qualification of the namespace in the master page file (which appeared to work fine in VS 2015).

Original markup in the non-functional MASTER tag was ...

Inherits="WebApplication1.Site"

working code (now has my namespace in place) ...

Inherits="CP.Web.Site"

Still not sure why this was needed but clearly something was not loading correctly before.
