LoginView fails to load

[tusmester]

After installing the WebPages package and visiting the main page of the default site, this error shows up instead of the login view:

Couldn't load /Root/System/SystemPlugins/Portlets/AdvancedLogin/LoginView

I was not able to reproduce the issue. It is possible that the installed Services and WebPages packages are not compatible. The first thing to try in this case is to upgrade all installed packages to their latest version from nuget.

"when i checked event viewer got this error message:

Hi @tusmester, @herflis,

FYI

1. I was getting this same issue. The issue was resolved after I modified the web.config file as follows:
   <compilation debug="true" targetFramework="4.7.1" > <assemblies> <add assembly="netstandard, Version=2.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51" /> </assemblies> </compilation>

3. My Env:
   VS Community 2017 v15.9.2
   .Net Framework 4.7.1
