InvalidOperationException: Cannot find compilation library location for package 'Microsoft.Win32.Registry'

[sunilshahi]

I am getting this error on two different servers. This is not happening in my local setup however. After playing around with the code I figured it out that this is only happening on the views where I have added

@await Component.InvokeAsync("NToastNotify.Toastr")

commenting this line of code works. But Off course toastr stops working.
I have ASP.net core 2.0 mvc application running in Windows Server 2012 R2 in IIS 8

An unhandled exception occurred while processing the request.

[nabinked]

which version are you using?

[sunilshahi]

version 3.0.2

[nabinked]

Seems like a bug with RazorCompilation. Can you refer to this issue and see whats going on . The issue also talks about a possible solution. Can you see if that works. I am guessing this has something to do with Razor PreCompilation which was enabled by default in ASP.NET Core 2.

[nabinked]

This seems to be a known issue with Embedded Views which is the case with this Library. Please refer to this comment here for the solution.

[sunilshahi]

Thank you.. Added <MvcRazorExcludeRefAssembliesFromPublish>false</MvcRazorExcludeRefAssembliesFromPublish> to .csproj and worked like a charm.

Great (y)
