VS2013 MVC 5專案升級VS2015

 

Tool：Visual Studio 2015 Ultimate Update 3
OS:Windows 10
.NET Framework : 4.6.x

將VS 2013 MVC專案，拿到VS2015的環境開起來，雖然程式可以正確編譯，但執行網站產生錯誤，訊息:

 

Could not load file or assembly 'Microsoft.Web.Infrastructure, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

檢視packages.config，似乎也沒有記錄有安裝'Microsoft.Web.Infrastructure’套件:

<?xml version="1.0" encoding="utf-8"?>
<packages>
  <package id="EntityFramework" version="6.0.1" targetFramework="net451" />
  <package id="Microsoft.AspNet.Mvc" version="5.0.0" targetFramework="net451" />
  <package id="Microsoft.AspNet.Razor" version="3.0.0" targetFramework="net451" />
  <package id="Microsoft.AspNet.WebApi" version="5.2.3" targetFramework="net451" />
  <package id="Microsoft.AspNet.WebApi.Client" version="5.2.3" targetFramework="net451" />
  <package id="Microsoft.AspNet.WebApi.Core" version="5.2.3" targetFramework="net451" />
  <package id="Microsoft.AspNet.WebApi.WebHost" version="5.2.3" targetFramework="net451" />
  <package id="Microsoft.AspNet.WebPages" version="3.0.0" targetFramework="net451" />
  <package id="Newtonsoft.Json" version="6.0.8" targetFramework="net451" />
</packages>

解法，使用Package Manager Console重新安裝'Microsoft.Web.Infrastructure'

 

Install-Package Microsoft.Web.Infrastructure

完成後網站就可以順利執行

檢視packages.config，MVC的版本並沒有隨之升級成新版

<?xml version="1.0" encoding="utf-8"?>
<packages>
  <package id="EntityFramework" version="6.0.1" targetFramework="net451" />
  <package id="Microsoft.AspNet.Mvc" version="5.0.0" targetFramework="net451" />
  <package id="Microsoft.AspNet.Razor" version="3.0.0" targetFramework="net451" />
  <package id="Microsoft.AspNet.WebApi" version="5.2.3" targetFramework="net451" />
  <package id="Microsoft.AspNet.WebApi.Client" version="5.2.3" targetFramework="net451" />
  <package id="Microsoft.AspNet.WebApi.Core" version="5.2.3" targetFramework="net451" />
  <package id="Microsoft.AspNet.WebApi.WebHost" version="5.2.3" targetFramework="net451" />
  <package id="Microsoft.AspNet.WebPages" version="3.0.0" targetFramework="net451" />
  <package id="Microsoft.Web.Infrastructure" version="1.0.0.0" targetFramework="net461" />
  <package id="Newtonsoft.Json" version="6.0.8" targetFramework="net451" />
</packages>

 

這時可以使用Package Manager Console更新所有套件為新版

update-package -Reinstall

這樣就完成升級做業了。packages.config：

<?xml version="1.0" encoding="utf-8"?>
<packages>
  <package id="EntityFramework" version="6.0.1" targetFramework="net461" />
  <package id="Microsoft.AspNet.Mvc" version="5.0.0" targetFramework="net461" />
  <package id="Microsoft.AspNet.Razor" version="3.0.0" targetFramework="net461" />
  <package id="Microsoft.AspNet.WebApi" version="5.2.3" targetFramework="net461" />
  <package id="Microsoft.AspNet.WebApi.Client" version="5.2.3" targetFramework="net461" />
  <package id="Microsoft.AspNet.WebApi.Core" version="5.2.3" targetFramework="net461" />
  <package id="Microsoft.AspNet.WebApi.WebHost" version="5.2.3" targetFramework="net461" />
  <package id="Microsoft.AspNet.WebPages" version="3.0.0" targetFramework="net461" />
  <package id="Newtonsoft.Json" version="6.0.8" targetFramework="net461" />
</packages>
