WebForms and ASP.NET MVC co-existence

问题

I am trying to make a WebForms project and ASP.NET MVC per this question. One of the things I've done to make that happen is that I added a namespaces node to the WebForms web.config:

<pages styleSheetTheme="Default">
  ...
  <namespaces>
    <add namespace="System.Web.Mvc"/>
    <add namespace="System.Web.Mvc.Ajax"/>
    <add namespace="System.Web.Mvc.Html"/>
    <add namespace="System.Web.Routing"/>
  </namespaces>      
</pages>

However, when I try to start the project, I get an error stating: "Compiler Error Message: CS0234: The type or namespace name 'Mvc' does not exist in the namespace 'System.Web' (are you missing an assembly reference?)"

I have System.Web.Mvc referenced. What is the issue?

回答1:

Add System.Web.Mvc in the compilation section,

<compilation debug="true">
    <assemblies>
        <add assembly="System.Core, Version=3.5.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089"/>
        <add assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
        <add assembly="System.Web.Abstractions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
        <add assembly="System.Web.Routing, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
        <add assembly="System.Web.Mvc, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
        </assemblies>
</compilation>

It's easier to start with an MVC project, and then start adding WebForms pages.

For your error, you will need to add references for the following assemblies:

System.Web.Mvc
System.Web.Routing
System.Web.Abstractions

There will be much more to add in the web.config to get MVC working correctly. To get it all, I'd suggest creating an MVC project, and merging the web.config files.
