Type MVC3 exists in two different assemblies.

I get an error when starting the MVC3 application.

i: \ Dev \ mvc3Project \ Views \ Shared \ EditorTemplates \ SelectListEnum.cshtml (13): error CS0433: The type "mvc3Project.UI.HtmlExtensions.HtmlAssist" exists as in "c: \ Windows \ Microsoft.NET \ Framework64 \ v4. 0.30319 \ Temporary ASP.NET files \ root \ fcb9f71c \ d519c72a \ assembly \ dl3 \ b333487e \ ed66abf6_51decb01 \ mvc3Project.DLL 'and' c: \ Windows \ Microsoft.NET \ Framework64 \ v4.0.30319 \ Temporary ASP.NET Files \ root \ fcb9f71c \ d519c72a \ App_Code.tfh8pvp4.dll '

I tried to delete all files in temporary ASP.NET files.

Here is my web.config. In fact, by default, VS is created for you.

I do not have a copy of System.Web.Mvc in the bin folder.

Any help would be appreciated.

Your conflict is located in a folder called App_Code, which generates its own DLL. It looks like you have a duplicate of the code in this folder with something mentioned somewhere else. You can remove this duplicate code and use the reference assembly or (if you need the code) rename the folder (as you indicated in your comment).

I would recommend that you either delete the code or rename the duplicate code, as this may cause confusion in the future.

Hope this helps!

If it does not work

Delete all bin folders and obj folders in your solution. Also delete the files in

c: \ Windows \ Microsoft.NET \ Framework64 \ v4.0.30319 \ Temporary ASP.NET Files \ root \ path

I fixed this problem in the web.config file:

FROM: <add assembly="System.Web.WebPages, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />

TO: <add assembly="System.Web.WebPages, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
