Where are the Assemblies for an ASP.NET Web Site When Running IIS Express

Question

I know that with dynamic compilation under an ASP.NET Web Site, code behind files get compiled into Assemblies. Where do these DLL's get stored when running IIS Express? Is it in memory only? I don't see them in the bin folder, or in the temp directory (C:\Windows\Microsoft.NET\Framework[64]\v4.0.30319). Typically I generate them when precompiling them whenever I publish. In this case, though, I don't see them.

Am I missing something?

Thanks.

UPDATE:

I did see dll's under C:\Users\Administrator\AppData\Local\Temp\Temporary ASP.NET Files\root

So I'm thinking it stores them there? This is Visual Studio 2012, .NET 4.5.

Please refer to this: http://msdn.microsoft.com/en-us/library/e22s60h9%28v=vs.85%29.aspx

It really should be in your Bin folder.

This is additional info for framework 4.5: http://msdn.microsoft.com/en-us/library/hh475319.aspx

Answer 2

It's quite likely not your bin folder. Everything gets copied into a set of temp folders.

I wrote a method for just this problem -

private string[] GetAssembly(string[] assemblyNames)
{
    string [] locations = new string[assemblyNames.Length];

    for (int loop = 0; loop <= assemblyNames.Length - 1; loop++)       
    {
         locations[loop] = AppDomain.CurrentDomain.GetAssemblies()
           .Where(a => !a.IsDynamic && a.ManifestModule.Name == assemblyNames[loop])
           .Select(a => a.Location)
           .FirstOrDefault();
    }
    return locations;
}
