Question

我试图在我的测试解决方案中生成脚手架组件。我右键单击我的项目，然后单击＆＃34;添加脚手架项目＆＃34;然后我用实体框架＆＃34;中的动作选择＆＃34; API控制器。在那里我选择我的模型类和上下文，当我点击Add时，它会抛出以下错误：

错误运行所选代码生成器时出错：＆＃39;未处理异常：System.TypeLoadException：无法加载类型＆＃39; Microsoft.VisualStudio.Web.Codegeneration.Core，Version = 1.1.0.0，Culture = neutral，PublicKeyToken = adb9793829ddae60＆＃39;，在Microsoft.VisualStudio.Web.CodeGeneration.Tools.Program.Main（String [] args）＆＃39;

我确信这是由解决方案的依赖性问题引起的。到目前为止，我已尝试包含Microsoft.VisualStudio.Web.CodeGeneration.Core库但未解决问题。

这些是我项目的依赖项：

Answer 1

由于依赖项中的错误版本和平台的不兼容代码生成器导致的问题。

打开/转换项目到VS2017社区并与VS2017的空白新对比显示问题。我强迫VS2015使用.Net Core 1.1.1和无法使用的代码生成器版本。

错误：

<PackageReference Include="Microsoft.AspNetCore.Authentication.Cookies" Version="1.1.1" />
<PackageReference Include="Microsoft.AspNetCore.Diagnostics" Version="1.1.1" />
<PackageReference Include="Microsoft.Extensions.Logging" Version="1.1.1" />

<PackageReference Include="Pomelo.EntityFrameworkCore.MySql.Design" Version="1.1.1-prerelease-10020" />
<PackageReference Include="Microsoft.VisualStudio.Web.CodeGeneration.Core" Version="1.1.0" />

右：

  <ItemGroup>
