在我的web.config文件中使用kendo.mvc.ui时出现编译错误

Question

I have an application in which I am using Kendo.Mvc.UI now I am creating another project in which I want to use Kendo.Mvc.UI so I added Kendo.Mvc.UI my bin folder see below Image for reference

and added the below code my main web.config in Pages > Namespaces

<add namespace="Kendo.Mvc.UI" />//the same code is working in my previous project.

and the below line in my web.config of which is in views folder

<add namespace="Kendo.Mvc.UI" /> //this is same in both the web.config 

but I am Getting the below error

Compilation Error Description: An error occurred during the compilation of a resource required to service this request. Please review the following specific error details and modify your source code appropriately.

Compiler Error Message: CS0246: The type or namespace name 'kendo' could not be found (are you missing a using directive or an assembly reference?)

Source Error:

Line 56: <add namespace="System.Web.Routing" />

Line 57: <add namespace="System.Web.WebPages" />

Line 58: <add namespace="kendo.mvc.ui" />

Line 59: </namespaces>

Line 60: </pages>

Answer 1

Using a project I currently have the following should work: in the main web.config

The directive should be here:

  <system.web>

   ...All other options removed for brevity....
    <pages>
      <namespaces>
        <add namespace="Kendo.Mvc.UI" />
      </namespaces>
    </pages>
  </system.web>

then in the web.config under your Views folder it should look like this:

  <system.web.webPages.razor>
    <host factoryType="System.Web.Mvc.MvcWebRazorHostFactory, System.Web.Mvc, Version=5.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
    <pages pageBaseType="System.Web.Mvc.WebViewPage">
      <namespaces>
        <add namespace="System.Web.Mvc" />
        <add namespace="System.Web.Mvc.Ajax" />
        <add namespace="System.Web.Mvc.Html" />
        <add namespace="System.Web.Optimization" />
        <add namespace="System.Web.Routing" />

        <add namespace="Kendo.Mvc.UI" />

      </namespaces>
    </pages>
  </system.web.webPages.razor>

Which based on your first image looks correct.

Assuming you have the web.config files configured correctly then intellisense should kick in after a shutdown and reopen of the project (if it doesn't recognise it straight away) when you type something like @Html.Kendo().<control here>

Assuming you have added the reference to the Kendo.Mvc and Kendo.Mvc.Export dll's into the project.

Failing this working have you tried to use the Telerik Kendo UI for MVC plugin for Visual Studio to upgrade the project as this may also help resolve this issue for you. If you don't have this option this try downloading it either package updater or via the progress updater software for Telerik.

As a side note I noticed in your image that you have a file System.Web.Http.Cors.xml which is in errored state. This may be preventing your project from building correctly which could be impacting the dll for kendo from being loaded correctly.

Personally when adding/referencing dll's in a project I prefer to add the files into a lib folder that sits alongside the project rather than adding the files into a bin folder as the bin folder is usually excluded from source control check-ins.
