I've recently followed this post on how to set up Umbraco and Glass Mapper. All of my code is set up the same as the example. However I keep on getting an error when I create a controller.
No parameterless constructor defined for this object.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.MissingMethodException: No parameterless constructor defined for this object.
Does anyone know how to fix this? Do I have to set something up in Castle Windsor?

Thanks!
I working on .net MVC Entity Framework (Code First).
I am not able to get Datacontext in repository classes functions when i call these functions from a static function in controller
. I am getting the Exception
"An exception of type 'System.NullReferenceException' occurred in YYYYYY.Web.dll(Default project dll) but was not handled in user code
Additional information: Object reference not set to an instance of an object."
i need to call static functions since i had to call some functions asynchronously.Like Report generation
This works perfectly fine when called from a non static function in controller.
Thanks in advance

So the full error that I get is:
Exception while attempting to inspect or instantiate type Microsoft.TeamFoundation.Framework.Server.WindowsProvider in assembly C:\Windows\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files\tfs\96d93be0\609f57b6\assembly\dl3\71c3ceb4\00f38a60_8f06cb01\Microsoft.TeamFoundation.Framework.Server.DLL: No parameterless constructor defined for this object.
and
Exception while attempting to inspect or instantiate type Microsoft.TeamFoundation.Framework.Server.TfsSyncAgent in assembly C:\Windows\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files\tfs\96d93be0\609f57b6\assembly\dl3\71c3ceb4\00f38a60_8f06cb01\Microsoft.TeamFoundation.Framework.Server.DLL: No parameterless constructor defined for this object.
Both are very similar
There are two main points to this:
1)Exception while attempting to inspect or instantiate type Microsoft.TeamFoundation.Framework.Server.WindowsProvider
2)Microsoft.TeamFoundation.Framework.Server.DLL: No parameterless constructor defined for this obj
I am making a server side event handler for tfs and I keep getting this error when i check in the item This is the tutorial i am following. Anyone know how to fix this problem?
Note: I did NOT have the folder "C:\Windows\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files\tfs\ " for some odd reason and had to create the directory and put the dll in it. That did not fix the problem either.
The Directory C:\Windows\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files is a directory used by IIS for Web Applications like TFS. Copies of the dlls of the web app will be deployed there. So when an exception is thrown it may happen, that you get this directory as the source of the problem instead of the real TFS-Directory.
Your problems seems to be, that you do not have a parameterless constructor in your ISubscriber. But a parameterless constructor is required!
No, you cannot add code to someone else's code.
What are you trying to accomplish? There's probably another way to do it.
I have a Delphi ActiveX project with 4 interfaces. Two of them have AutoComObject factories for their CoClasses. All the methods of the interfaces are declared with safecalls. In the interfaces with the factories, if a exception is thrown in any method, the caller receives an EOleException with the exception message from the original exception in the activex. But in the other two interfaces any exception gets masked as EOleException with the message masked to "Catastrophic Failure".
Anyone knows why this is happening, and how to make the original exception message not get masked?
If an unhandled exception escapes a safecall method of a class, TObject.SafeCallException() is called to convert the exception into an HRESULT error code, which is then returned by COM to the caller. By default, TObject.SafeCallException() always returns E_UNEXPECTED ($8000FFFF). A class can override SafeCallException() to return a more meaningful HRESULT. TComObject and TAutoIntfObject do exactly that, for instance (they also call SetErrorInfo() to set detailed information about the exception, which the caller can retrieve using GetErrorInfo() if desired). So it sounds like your two AutoComObject-based objects have a SafeCallException() implementation, and your other two objects do not.
I have a controller that takes multiple arguments and I am using Unity to create an instance of that controller. The problem is that under certain circumstances Unity is not able to build all of the objects that are needed for my constructor so it throws an Exception.
[MissingMethodException: No parameterless constructor defined for this object.]
How do I handle this error and show a custom error page to the user?
Don't handle that error, either create parameterless constructors for said objects that are instantiated, or don't create them in the constructor. Handling those exceptions would just be masking the issue.
