I ve had this a couple of times   It s especially frustrating as it s right off the bat  and the error message holds no clue as to what might be the issue   To fix this  right click your project title  in this case  TestMvcApplication  and click build   This forces the code to compile before you run it   Don t ask me why  but this has been the solution 100  of the time for me

I have also faced the same issue and somehow IIS Express s config file is not pointing to the correct bin directory for the website  So editing the Config file which will be in Documents IISExpress config fixed the issue  Just point to the correct physical path in Site tag as shown below          lt site name  MYWEBSITE  id  4  gt               lt application path     applicationPool  Clr4IntegratedAppPool  gt                   lt virtualDirectory path     physicalPath  D  MYWEBSITE    gt               lt  application gt               lt bindings gt                   lt binding protocol  https  bindingInformation    44305 localhost    gt                   lt binding protocol  http  bindingInformation    6689 localhost    gt               lt  bindings gt           lt  site gt

For completness sake I included what my issue was and how I solved it   If your like me and have httphandlers via web config and you have redirects from your global asax cs  maybe in Session Start     like in my case you get this error if your startup project does not have a reference defined which points to the target where your httphandler is pointing    but you wont get build errors  just runtime errors   So     Double check your web config for any external items Double check your startup project has all the references it needs    Cheers

If Andy Copley s answer worked for you but simply rebuilding the solution doesn t work  then go to Project   Project Dependencies and make sure that the project that has your Global asax cs file in it is dependent on all the other non-test projects in the solution

I had the same problem  mine was because the web project had a platform target of x86  I was running on a 64-bit machine  other projects in the solution were set to 64-bit   To check your settings  right click the project and choose Properties  On the Build tab  check the value of  Platform Target    Also check your solution s build configuration  Build menu   Configuration Manager  to check all your projects are being built to the same platform   In both cases  make sure you check the settings both for debug and release mode - otherwise you ll get it working on your machine but not when you deploy it

I had the same error and none of your solutions helped  I think my problem was simply the name that I had chosen for the project  I had named my project  interface  which when I got the parse error it said that it couldn t load      Line 1   lt    Application Codebehind  Global asax cs  Inherits   interface MvcApplication  Language  C        Where there was an     sign for some reason  I am guessing the word  interface  is reserved for something else and it added the   symbol but that obviously broke something  I deleted the project and made a new one with a different name with no problems

This issue is complicated because it s easy to confuse the root cause with whatever the immediate cause happens to be   In my case  the immediate cause was that the solution is configured to use NuGet Package Restore  but the server was not connected to the internet  so NuGet was unable to download the dependencies when building for the first time   I believe the root cause is simply that the solution is unable to resolve dependencies correctly  It may be an incorrect path configuration  or the wrong version of an assembly  or conflicting assemblies  or a partial deployment  But in all cases  the error is simply saying that it can t find the type specified in global asax because it can t build it

I had a lot of problems and errors to solve  some of the above answers helped  but what the final trick that made it work for me was  Go to your project  click properties   Go to the Package Publish Web tab and make sure the configuration is set to Release and Platform to All Platforms   Last make sure that the  Items to deploy  applies to all deployment methods   is set to  All files in this project folder   It then worked fine for me

I have found that when you are forced to use the Configuration Manager to run under x86 or anything other than the standard project  out of the box  settings  the IDE creates a bunch of sub directories under the bin folder for the web project   Once this starts happening  if the Cassini server is running  then the project does not serve properly   I fixed it by going into the Web Project properties -  Build settings and changing the Output Path to be bin   Then rebuild and all works as it should

I solved my problem by renaming lots of things   If your problem is cause by creating a new project from copying an existing project like me  you may try these steps    rename solution - in solution explorer rename project - in solution explorer rename namespace - in code rename assembly name and default namespace - in project property application rename AssemblyTitle and update GUID - in project property application aseembly information rebuild and run   some of these steps may be worthless  but following them all should solve your problem
