c# - MvcScaffolding 是否与 VS 2015 兼容？

Question

我最近升级到 VS 2015，现在当我尝试使用我的脚手架之一时出现以下错误:

Scaffold : Cannot get an instance of EnvDTE.DTE
At line:1 char:1
+ Scaffold Entity
+ ~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (:) [Invoke-Scaffolder], InvalidOperationException
    + FullyQualifiedErrorId : T4Scaffolding.Cmdlets.InvokeScaffolderCmdlet

看起来有一个 similar issue early on with VS 2013但问题已通过更新 2 解决。

我可以做些什么来让 mvcScaffolding 再次工作，或者是否有一种新的方式来构建我的代码？

这是我的自定义脚手架之一的示例:

RestApi.ps1

[T4Scaffolding.Scaffolder(Description = "Enter a description of RestApi here")][CmdletBinding()]
param(
    [parameter(Mandatory = $true, ValueFromPipelineByPropertyName = $true)][string[]]$EntityNames,
    [parameter(Mandatory = $false, ValueFromPipelineByPropertyName = $true)][string]$Inherit,    
    [string]$Project,
    [string]$CodeLanguage,
    [string[]]$TemplateFolders,
    [switch]$Force = $false
)

$outputPath = "ExampleOutput"  # The filename extension will be added based on the template's <#@ Output Extension="..." #> directive
$namespace = (Get-Project $Project).Properties.Item("DefaultNamespace").Value
$baseInherit = $Inherit
if($Inherit -eq ""){
    $baseInherit = "BaseRestController"
}

foreach($EntityName in $EntityNames){
    $split = $EntityName.Split(":")
    $EntityName = $split[0]
    if($split[1]){
        $Inherit = $split[1]
    }else{
        $Inherit = $baseInherit;
    }
    $Entities = Get-PluralizedWord $EntityName

    $outputPath = "ApiControllers\"+$Entities+"Api.cs"  # The filename extension will be added based on the template's <#@ Output Extension="..." #> directive
    Add-ProjectItemViaTemplate $outputPath -Template RestApiTemplate `
        -Model @{ 
            Namespace = $namespace;
            Entity = $EntityName;
            Entities = $Entities;
            Inherit = $Inherit
        } `
        -SuccessMessage "Added RESTApi at {0}" `
        -TemplateFolders $TemplateFolders -Project $Project -CodeLanguage $CodeLanguage -Force:$Force
}

RestApiTemplate.cs.t4

<#@ Template Language="C#" HostSpecific="True" Inherits="DynamicTransform" #>
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Http;
using <#= Model.Namespace #>.Models;
using <#= Model.Namespace #>.Models.ViewModels;

namespace <#= Model.Namespace #>.ApiControllers {
    [RoutePrefix("api/<#= Model.Entities.ToLower() #>")]
    public class <#= Model.Entities #>Controller : <#= Model.Inherit #><<#= Model.Entity #>, <#= Model.Entity #>ViewModel> {
        public <#= Model.Entities #>Controller() : base("<#= Model.Entity #>"){
        }

        // Use StandardActions to override standard behavior
        #region StandardActions
        // GetById, All, Add, Update, Delete

        #endregion

        // Use ExtendedActions to add additional behavior to the API
        #region ExtendedActions

        #endregion
    }
}

我在 VS2015 中遇到了同样的错误。我提取了源代码，修复了错误，并上传了具有链接依赖项的新 NuGet 包。 3 个新包是:

• MvcScaffolding.VS2015
• T4Scaffolding.VS2015
• T4Scaffolding.Core.VS2015

先卸载MvcScaffolding及其依赖，T4Scaffolding, & T4Scaffolding.Core。如果您随后只需安装 MvcScaffolding包，其他包将被拉过。希望这可以帮助别人。

干杯。
