Make sure the Inherits is pointing to the right namespace of the class because when you create an MVC project under a solution the Inherits value will miss the project name  Therefore you need to fill the gap project name  manually    lt br gt  lt br gt  lt    Application Codebehind  Global asax cs  Inherits  solutionName projectName MvcApplication  Language  C     gt

Nothing above worked for me  Everything was correct    Close the Visual Studio and reopen again  This fixed the issue in my case   The problem could have been caused by different versions of visual studio  I have Visual studio 2017 and 2019  I had opened the project on both the versions simultaneously  This might have created different set of vs files    Close any instance of the Visual Studio and open again

Problem could occur if you have changed the namespace of your project   Change the Namespace from Project Properties and also replace all old Namespace with new ones  Renaming to correct namespace might fix the issue   Source

I had the same error on IIS Express  In my case  I had two projects as startup projects I changed properties of the solution to single startup project and ran it  then changed it to previous settings and ran the solution again and no error occurred again

In my case  I copied the project and pasted it as another project  The Global asax file contains the wrong file name  so I just change    lt    Application Codebehind  Global asax cs       Inherits  WrongAppname MvcApplication  Language  C     gt    to    lt    Application Codebehind  Global asax cs       Inherits  RightAppName MvcApplication  Language  C     gt

In my case  it was also caused by old dlls  Clean all your files then rebuild

User · Answer

I was also getting this error  I deleted dlls from my debug folder and when I started a new instance for debug I got this error  For me the issue was due to the the build setting  Release was selected in the build type  I just changed it to debug and then application was working fine

In my case problem occurred after namespace renaming  I didn t use external tool like Re-sharper  I did renaming manually    In that process  Views Web config file was left unchanged  After replacing old namespace name with the new one in this file  the error disappeared

The only solution that worked for me   Run  Type command  Temp  -  Deleting  Temporary ASP NET Files     Other solutions I have tried  which didn t work    Cleaning Rebuilding Cleaning bin  obj folders Changing namespace

It s quite weird  Every time I face this issue  have different solution  This time all of the previous fixes failed then I changed project output path from Bin to    Build Bin  It failed  Reverted output path to the previous value   i e   Bin fixed the issue

User · Answer

It may occur due to the clean solution The dlls in the bin will be removed  1 Clean Solution 2 Rebuild the solution 3 If the build process have failed not all the necessary dlls will be stored in the bin  This is another scenario where the error occurs

I found that this problem happened to me and to a colleague after changing the name of our solution project    The issue resulting from my colleague  I pulled changes into my branch and had the error  In my bin folder I found the old  dll files sitting with the newly named  dll files  Deleted the old ones and the problem went away

User · Answer

In My case the issue was fixed by changing the solution platform from AnyCPU to x86

User · Answer

You can change it by editing Globas asax file  not Global asax cs   Find it in app folder in windows explorer then edit   lt    Application Codebehind  Global asax cs  Inherits  YourAppName Global  Language  C     gt   to   lt    Application Codebehind  Global asax cs  Inherits  YourAppName MvcApplication  Language  C     gt

User · Answer

Solved  just renamed the Global asax or delete it fixed the problem     Other known related bugs I found on  the web    Global asax cs  must inherit from HttpApplication - gt  public class MvcApplication   HttpApplication Project output must be the bin folder and not Bin Debug  etc  Iss application pool is not in the correct  net version

User · Answer

Same issue i faced   when copy the project from another system  In my case i fixed this issue   delete everythings from inside Bin folder  Clean  amp  Rebuild the app again  Hope this will help

In my case my site on IIS was pointing to a different project than the one I was running on visual studio

User · Answer

I faced similar error  tried all the suggestions above  but did not resolve  what worked for me is this   Right-click your Global asax file and click View Markup  You will see the attribute Inherits  nadeem MvcApplication   This means that your Global asax file is trying to inherit from the type nadeem MvcApplication   Now double click your Global asax file and see what the class name specified in your Global asax cs file is  It should look something like this   namespace nadeem    public class MvcApplication  System Web HttpApplication                  But if it doesn t look like above  you will receive that error  The value in the Inherits attribute of your Global asax file must match a type that is derived from System Web HttpApplication   Check below link for more info   Parser Error  Server Error in   39    39  Application
