Recently there was some upgrade happened from frame work 2.0 to 4.0, so after building the project when we click the application it is throwing error? what does it mean “Unhandled Microsoft .NET Framework Exception exception occurred in tander.exe[400]” ? What does [400] means ? Does it related to any signing issues?
