"The directory name is invalid" with the latest image

[MichaelLogutov]

Using microsoft/aspnet:4.6.2-windowsservercore-10.0.14393.1358 image I've got this error when launching site that was previously running fine:

Compiler Error Message: CS0016: Could not write to output file 'c:\Windows\Microsoft.NET\Framework64\v4.0.30319\Temporary ASP.NET Files\root\ab2094c7\6e6df95\App_global.asax.wz646n9b.dll' -- 'The directory name is invalid. '

I thinks it's permission issue

@MichaelLogutov could you please share your repro steps? Did you just simply migrate your application to the new ASP.NET 4.6.2 image? Was there any operations performed before your migration?

Ok. False alarm. But if anyone encountered this error - it's because I've removed Microsoft.CodeDom.Providers.DotNetCompilerPlatform package. In that case the error a bit missleading - it tries to "compile" global.asax but can't (needed c# 6 - dunno why) and falling with this strange error.
