Answer 1

Empty/Delete the 'bin' folder of your start-up project!

Clear the Temp ASP.Net files/assemblies! See this SO answer

Generally, the location should be, the below folder. If you are using other version of framework, then please refer to the SO link I mentioned to find details for cleaning the temp folders for various version of framework.

C:/Windows/Microsoft.NET/Framework/v4.0.30319/Temporary ASP.NET Files
