I am working on a WCF project (.net version is 4.0) . In one of my service project, it is getting build successfully. While right clicking the .svc file and choose option 'View in browser' I get error as given below.
Could not load file or assembly 'Antlr3.Runtime' or one of its dependencies. The parameter is incorrect. (Exception from HRESULT: 0x80070057 (E_INVALIDARG))
It was working fine previously. I deleted the temporary site files but no luck.
Could you please help me to solve this problem?
