[Fix] - Attempt by security transparent method WebMatrix WebData PreApplicationStartCode Start
Scenario :
Migrating a project created with MVC current version to the next version. The migrated project throws error at runtime.
Error :
Attempt by security transparent method 'WebMatrix.WebData.PreApplicationStartCode.Start()' to access security critical method 'System.Web.WebPages.Razor.WebPageRazorHost.AddGlobalImport(System.String)' failed
Fix :
- The solution is to install Nuget Package Microsoft.AspNet.WebHelpers as follows:
Install-Package -Id Microsoft.AspNet.WebHelpers
- Upon installing Microsoft.AspNet.WebHelpers via NuGet the next error that follows is
- "Could not load file or assembly 'WebMatrix.Data, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)."
- To fix the above error, install the below Nuget Package:
Install-Package Microsoft.AspNet.WebPages.Data.
- Now close and reopen the upgraded MVC projects to execute without errors.
