TypeInitializationException thrown for Program class

My Windows Forms application was working earlier, however suddenly it stopped working. I am getting following exception:

enter image description here

With exception details as follows:

System.TypeInitializationException was unhandled
Message: An unhandled exception of type 'System.TypeInitializationException' occurred in mscorlib.dll
Additional information: The type initializer for 'NotificationTester.Program' threw an exception.

When I click OK, the VS windows then shows following:

The solution was working fine earlier. I don't get whats going wrong.


So: either one of the field-initializers, or the static constructor, for Program - is failing. Find out why. Note: the InnerException has the actual exception that was raised, but basicaly: just debug the field initializers and static constructor. So look inside the Program class for either:

static SomeType someField = /* some non-trivial expression or method call */ 


static Program() {
    // stuff
