One or more errors occurred. (Cannot find compilation library location for package 'Microsoft.NETCore.App') (ca5ca414)

I have my .NET Core 2.2 library that has an unexpected behavior on my IIS Server.

I got this issue One or more errors occurred. (Cannot find compilation library location for package ‘Microsoft.NETCore.App’) (ca5ca414).

Note that this issue doesn’t happened when I run the project locally.

Also, I don’t use embedded template, I use string as template.

I tried to put in my .csproj (of my library and in my web app (.Net core API 2.2)) :

< MvcRazorExcludeRefAssembliesFromPublish>false</ MvcRazorExcludeRefAssembliesFromPublish> < CopyRefAssembliesToPublishDirectory>false< /CopyRefAssembliesToPublishDirectory> < MvcRazorCompileOnPublish>false< /MvcRazorCompileOnPublish> < PreserveCompilationContext>true< /PreserveCompilationContext>

Without any result.

Code :

FluentEmail.Core.Email.DefaultRenderer = new RazorRenderer();
            var sender = new MailgunSender("@@@", "@@@");
            FluentEmail.Core.Email.DefaultSender = sender;

 var fluentEmail = FluentEmail.Core.Email
                    .From(email.Sender)
                    .To(email.Recipient.Email)
                    .Subject(email.Content.Subject)
                    .UsingTemplate(template, content);

                var response = await fluentEmail.SendAsync();

There is anything that I miss ?

In case you wonder, that’s the proper fix, just add these property groups to your entry point csproj. It has to be the entry point project, so the ASP.NET core web project, or your console project, etc

  <PropertyGroup>
    <!-- This group contains project properties for RazorLight on .NET Core -->
    <PreserveCompilationContext>true</PreserveCompilationContext>
    <MvcRazorCompileOnPublish>false</MvcRazorCompileOnPublish>
    <MvcRazorExcludeRefAssembliesFromPublish>false</MvcRazorExcludeRefAssembliesFromPublish>
  </PropertyGroup>
