I'm having problem to run C# Form project (using Visual Studio 2008 professional edition).

When I try to run the project which I already ran, it says "Error while trying to run project:could not load file or assembly 'WindowsFormsApplication1' one of its dependencies. The module was expected to contain an assembly manifest".

After this error im not able to run any Form or any other project. Please tell me why this error occured and a way to fix this problem.

Thank You.

that can be caused by a software that has been installed in the computer and was corrupted.then what needs to be done is to re-install it and then start the programme again

Yesterday it worked good.. I shutdown my system and came back to my work with the project today,
it is showing the error

Error while trying to run project: Could not load file or assembly 'WindowsApplication1' or one of its dependencies.
The module was expected to contain an assembly manifest.

1. I set my project as startup project
but no use
2. Deleted the Temp folder
then also getting same error
3. I Removed all the references and added freshly
but same error exists

I have resolved this problem. Copy the the name of your namespace, then go to the property window for your project and paste it in the text box of assembly name.

Solution 1

This error means that the application it's trying to run is not there. I would say this means your build failed due to an error in your code.
