Although i am hosting the same application under IIS-8 and it is working well. but if i run the same web application inside Visual studio i will get the above error. i am using windows server 2012 r2.

can anyone adivce why my project is not working when i try running it inside VS? and this problem appeared all of a sudden i mean last week i was able to run the application without any problem.. Thanks

here is the event viewer errors regarding my problem , one related to iis-express, while the other related to VS:-

Are you running VS in an elevated mode? "Run as Administrator"? - Boyd P
@BoydP now if i run it as an admin, and i run the project, my remote desktop connection will end and the vm will restart.. now what i did (based on the reply from Munam) i copied the whole project folder from its original location c:\users\admin\Visual Studio...\project\... to be under D:\ drive , then i clean>>build>run the project and it worked well.. so seems the problem is somehow related to running the project from the C:\ drive ! baring in mind that this problem appears all of a sudden,, as it used to work well last week.. maybe this problem is related to installing some windows updates - john Gu
@BoydP but at the end i want my project to run from its original location at the c;\ drive ... - john Gu

Have u checked the "most likely causes". Possibly it is permissions issue. You may need to check startup project or you may need to review your web.config file
