RazorEngine.NetCore：名称“ PopWriter”在当前上下文中不存在

如何解决RazorEngine.NetCore：名称“ PopWriter”在当前上下文中不存在

我陷入了RazorEngine.NetCore库的问题。我在netstandard2.0库中使用它，.NET Core应用程序和.NET 4.7应用程序（FullFramework）都在使用它。

对于某些模板，好的，它工作正常。但是对于某些模板，在编译模板时，它开始在生成的类内部使用某些方法，例如PushWriter和PopWriter。

IRazorEngineservice _razorService = RazorEngineservice.Create(new TemplateServiceConfiguration()
        {
            ReferenceResolver = new MyIReferenceResolver(),Debug = true,EncodedStringFactory = new RawStringFactory(),BaseTemplateType = typeof(CustomTemplateBase<>)
        });

然后，我从库（一个cshtml视图）中添加模板以及用作模型的类型：

_razorService.AddTemplate(name,ReadTemplate(template));
_razorService.Compile(name,type);

但是当它碰到Compile方法时，我得到了这个错误：

Errors while compiling a Template.
Please try the following to solve the situation:
  * If the problem is about missing/invalid references or multiple defines either try to load 
    the missing references manually (in the compiling appdomain!) or
    Specify your references manually by providing your own IReferenceResolver implementation.
    See https://antaris.github.io/RazorEngine/ReferenceResolver.html for details.
    Currently all references have to be available as files!
  * If you get 'class' does not contain a deFinition for 'member': 
        try another modelType (for example 'null' to make the model dynamic).
        NOTE: You CANNOT use typeof(dynamic) to make the model dynamic!
    Or try to use static instead of anonymous/dynamic types.

我将Microsoft.AspNetCore.Mvc和Microsoft.AspNetCore.Mvc.Razor添加到项目引用中，也添加到了MyIReferenceResolver中，但是没有成功。

在Roslyn生成的异常中可以看到的部分生成的代码是这样的：

BeginWriteAttribute("style"," style=\"",8783,"\"",8878,3);
            WriteAttributeValue("",8791,"min-width:100%;",15,true);
            WriteAttributeValue(" ",8806,new Microsoft.AspNetCore.Mvc.Razor.HelperResult(async(__razor_attribute_value_writer) => {
                PushWriter(__razor_attribute_value_writer);
                                                                                                                                                                                                if (f.something) {WriteLiteral("border-right: 1px solid #dddddd;");
                                                                                                                                                                                                                                                                    }PopWriter();
            }
            ),8807,70,false);

任何人都曾经经历过吗？

谢谢！
