Question

我有一个ASP Core 1x应用程序，运行正常，已升级到2.x。在dev中运行正常，但是一旦部署，我收到了有关voth 2.11和2.1.13中存在的PrerenderTagHelper的以下错误。

The type 'PrerenderTagHelper' exists in both 'Microsoft.AspNetCore.SpaServices, Version=2.1.1.0, Culture=neutral, PublicKeyToken=adb9793829ddae60' and 'Microsoft.AspNetCore.SpaServices, Version=2.1.13.0, Culture=neutral, PublicKeyToken=adb9793829ddae60'
+
        private global::Microsoft.AspNetCore.SpaServices.Prerendering.PrerenderTagHelper __Microsoft_AspNetCore_SpaServices_Prerendering_PrerenderTagHelper;

我已经将MvcRazorCompileOnPublish和PreserveCompilationContext添加到了csproj文件中，该文件至少显示了与部署时相同的错误。以下是我的csproj。

Answer 1

已跳到ASP Core 3.0，并且再次正常工作。没有锻炼导致它在2.x中失败的原因。

两个Microsoft.AspNetCore.SpaServices中都存在类型PrerenderTagHelper
