aspnet_regiis -i gives “webengine4.dll” error after installing MVC 4
问题 I recently installed MVC 4 Beta, and, when I hit F5 for any of my MVC 4 projects I get the error below. Also, if I run aspnet_regiis -i , I get the same screenshot. Is there a way to repair just this one dll? Or, should I wipe out everything .NET- and MVC-related on my machine, then re-install .NET + MVC 4? Thanks. 回答1: Apply official Microsoft Update for the .NET Framework 4 (KB2468871) Download link 来源: https://stackoverflow.com/questions/9444831/aspnet-regiis-i-gives-webengine4-dll-error
