System.Web.HttpCompileException (0x80004005): (0): Error CS0016: Failed to write output file

After you re-system, the IIS ASP. NET site always appears:

System.Web.HttpCompileException (0x80004005): (0): Error CS0016: Failed to write output file "c:\Windows\Microsoft.NET\Framework64\ V4.0.30319\temporary ASP. Files\root\8a066f10\5b61ede0\app_web_index.aspx.cdcab7d2.m4fr5omv.dll "--" access denied. ”

The first feeling is definitely to temporary ASP. NET files to the folder plus permissions, but add permissions, or not, silly, the original has been so dry.

Check the information, some people say also to C:\Windows\temp folder plus permissions, sure enough a plus, immediately good.
