trying to do asp.net mvc development from vmware fusion

Question

the issue is that my source is hosted on the host machine (in this case a mac book pro) and visual studio wants to be able to monitor the web.config for changes so it is throwing the error:

An error occurred loading a configuration file: Failed to start monitoring changes to: \path\to\web.config

I have tried to add the HKLM\Software\Asp.Net\FCNMode=1 but it doesn't seem to work. Also, I don't see moving the source to the VHD as a viable option due to version control issues.

Windows 7 64-bit Visual Studio 2008 VMWare Fusion 3.01

Thanks.

Answer 1

You have the right idea, but need to edit the correct key for Windows 7.

• Open up RegEdit
• Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\ASP.NET
• Add a REG_DWORD registry entry called FCNMode and set its value to 1

Re-boot and you should be good to go. The "Wow6432Node" allows you to set this for Windows 7 64-bit Visual Studio.

Answer 2

It looks like you can now change FCNMode in your web.config. They probably added it in .NET 4.5, could not find any of documentation but this, but it seems to work.

<system.web>        
    <httpRuntime fcnMode="Disabled"/>
