Webconfig error with the site online

I'm trying to publish a web site.

The publication works perfectly, but when I try to access the address it returns me the following error:

Parser Error Message: Could not load file or assembly 'Microsoft.Web.Helpers' or one of its dependencies. This assembly is built by a runtime newer than the currently loaded runtime and cannot be loaded.

Source Error:

Line 293: Line 294: Line 295: Line 296:

Line 297:

Source File: C:\Windows\Microsoft.NET\Framework\v2.0.50727\Config\web.config Line: 295

Assembly Load Trace: The following information can be helpful to determine why the assembly 'Microsoft.Web.Helpers' could not be loaded.

WRN: Assembly binding logging is turned OFF. To enable assembly bind failure logging, set the 开发者_开发百科registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1. Note: There is some performance penalty associated with assembly bind failure logging. To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].

This does not happen when I'm running on the local site.

The application was developed and Sql Server WebMatrix Compac 4

If you read the error message it says "Could not load file or assembly 'Microsoft.Web.Helpers' or one of its dependencies. This assembly is built by a runtime newer than the currently loaded runtime and cannot be loaded." If you then look at the version of the ASP.NET that this site is attempting to run under, it is ASP.NET Version:2.0.50727.4209.

Web Pages and the Web Helpers library need Version 4.0. Make sure the site targets the correct version of ASP.NET.

For missing assemblies a simple solution is to just bundle them with your project. Go to your project -> references -> find this microsoft web helpers ref -> open the properties panel and set Copy Local to True

Edit: Also try setting assembly binding logging.

I suspect that your web.config is fine and that there is an assembly missing from your deployment.

You probably have to include microsoft.web.helpers in your deployment package or simply copy it to the bin folder.

You might find that there are other assemblies missing but you should be able to pick them off one by one.

There is a previous question Hosting WebMatrix Page

that lists all of the dlls you have to deploy and also suggests using Webdeploy
