I do not remember the updates I made. Is there any way to fix this?

Answer 1

I think the problem is resolved, but if not, use this package from Nuget:

 Install-Package Microsoft.AspNet.Mvc -Version 5.0.0 

I spent a day on this error, but this one line did the job for me

Answer 2

tried., Install-Package-Microsoft.AspNet.Mvc -Version 5.0.0 as well., Install-Package -Id Microsoft.AspNet.WebHelpers

both without success, finally had to update all packages through nuget., works !!

"If you are using visual studio, open the nuget package windows and run Update-Package, this will update your entire dll to the latest version. If it still does not work, see this page: http://www.asp.net/mvc/ tutorials / mvc-5 / how-to-upgrade-an-aspnet-mvc-4-and-web-api-project-to-aspnet-mvc-5-and-web-api-2 "

I managed to solve the problem by following the link: http://www.asp.net/mvc/tutorials/mvc-5/how-to-upgrade-an-aspnet-mvc-4-and-web-api-project-to- aspnet-mvc-5-and-web-api-2

Answer 4

I got this error when deploying a site on which Mvc was upgraded from 4 to 5, but I did not update web.config.

By changing this:

 <dependentAssembly> <assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35" culture="neutral" /> <bindingRedirect oldVersion="0.0.0.0- 4.0.0.0 " newVersion=" 4.0.0.0 " /> </dependentAssembly> 

:

 <dependentAssembly> <assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35" culture="neutral" /> <bindingRedirect oldVersion="0.0.0.0- 5.0.0.0 " newVersion=" 5.0.0.0 " /> </dependentAssembly> 

solved the problem for me.

Answer 5

The same error also occurred to me. This has been fixed by installing the NuGet package.

  Install-Package -Id Microsoft.AspNet.WebHelpers 

Answer 6

I had a similar problem and solved it based on the article Upgrading Razor 2.0 to 3.0 using Asp.net MVC by Anthony Fassett

In my Web.Config, the following code was missing:

 <dependentAssembly> <assemblyIdentity name="System.Web.WebPages.Razor" publicKeyToken="31bf3856ad364e35" /> <bindingRedirect oldVersion="1.0.0.0-3.0.0.0" newVersion="3.0.0.0" /> </dependentAssembly> 

Answer 7

To solve this problem, there are several solutions:

• Follow the instructions to update your asp.net solution
• Remember to remove the Microsoft-Web-Helpers dll and install the Microsoft.AspNet.WebHelpers nuget package

Then make sure that you have updated all your nuget packages (use the "Upgrade-Package") and check your dll in web.config.

The error is probably an action in the old DLL when you convert your project.

Answer 8

In my case, installing nuget changed my Web.Config:

  <dependentAssembly> <assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35" /> <bindingRedirect oldVersion="1.0.0.0-5.1.0.0" newVersion="1.1.0.0" /> </dependentAssembly> 

newVersion="1.1.0.0" ** must be newVersion="5.1.0.0"

Answer 9

Right click for project -> Nuget Package Management for a solution than find

Microsoft.AspNet.Mvc and Microsoft.Net.Compilers update the latest versions

Answer 10

In my case, it was an incompatibility problem. I had theses pacakges:

• Microsoft.AspNet.Mvc version 4.x
• Microsoft.AspNet.Razor and Microsoft.AspNet.WebPages , version 3.x

I assume that upgrading Mvc to 5.x would work, but I needed to keep Mvc 4.x, so I had to downgrade Razor and Mvc to 2.x. To do this, you just need to install an older version, for example:

 Install-package Microsoft.AspNet.WebPages -version 2.0.30506 Install-Package Microsoft.AspNet.Razor -Version 2.0.30506 

After overriding these packages, the first error disappeared, but there was another error related to the problem in web.config . I had to change the binding binding for Razor:

 <dependentAssembly> <assemblyIdentity name="System.Web.Razor" ... /> <!--bindingRedirect oldVersion="0.0.0.0-3.0.0.0" newVersion="3.0.0.0" /--> <bindingRedirect oldVersion="0.0.0.0-2.0.0.0" newVersion="2.0.0.0" /> </dependentAssembly> 

I don’t know why, but the binding redirection was not updated by the Nuget installation that was supposed to do this.

Answer 11

I solved my problem by applying the "Install-Package Microsoft.AspNet.Mvc" command.

After that, I solved my project using the Web API.

Answer 12

I got this error when I updated the NuGet package - Microsoft.AspNet.Web Pages ' version 3.2.3. I use VS2012, creating a new ASP.NET MVC 4 > web application with an Internet application template using Windows authentication or Windows Azure authentication.

The update may not be compatible with other components, and these other components should also be updated. Other answers suggest updating Microsoft.AspNet.Mvc , Microsoft.Net.Compilers and / or Microsoft.AspNet.WebHelpers .

Answer 13

I am working on an ASP.NET Web API project and get the same problem after adding the following nuget CacheCow.Server.EntityTagStore.SqlServer

He decided to install this

 Install-Package Microsoft.AspNet.Mvc 

Answer 14

Install-Package -Id Microsoft.AspNet.WebHelpers

Microsoft.AspNet.Mvc Installation Package -Version 5.0.0

It worked for me
