Answer 1

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
    {
    ....

If it doesn't, then you will receive the error you received. The value in the Inherits attribute of your Global.asax file must match a type that is derived from System.Web.HttpApplication.

Answer 2

This error causes when Namespace is Renamed.

-

1. Go to Folder Explore ( Don't Use Solution Explore) . Find Global.asax File

.

2. Open File (in Notepad / any editor) and Change Replace Old namespace name New Namespace

.

3. Save It should work now..

Answer 3

I had the same problem and that was because I didn't build the solution. Rookie mistake. Just: build solution (Ctrl + shift + b)

Answer 4

In my situation I was getting this same error. I am using git along with Source Tree for version control. In my case git had been enabled in the project, but I wasn't using Visual Studio to stage my commits, etc .. I was using Source Tree. This doesn't really matter what I was using the problem is that visual studio had put the following line into my gitignore file:

#Build Results
[Bb]in/

That was ignoring the bin folder so my bin folder never got pushed up to the server, once I removed that line and committed the entire bin directory and pushed it up to the server and then went to the server and did a git pull. The bin folder showed up and everything started working!

BTW, my final gitignore file (#Build results) section ended up looking like this:

# Build results

[Dd]ebug/
[Rr]elease/
x64/
build/
[Oo]bj/

Im still unsure if I need the Obj folder to be pushed to the server, but everything is working fine now.

Answer 5

When I got this error it was after I deleted and recloned a Git folder; what happened was I forgot to build the solution in VS2010. As soon as I built it, everything worked fine. Sometimes it's something really simple like that.

Answer 6

I had this problem after adding a new project to my solution. The solution built, no problem - but then bombed at runtime.

It turned out that the new project was set to target .NET 4.6.1 by default, whereas everything else in mhy solution targets .NET 4.5.

Changing the target framework in the new project to .NET 4.5 to match the others fixed the problem.

(thanks for no warning on that one Microsoft guys)
