MVC Html.ActionLink() fails weirdly with routeValues parameter in Asp.Net

It seems simple. In an MVC view page you have an @Html.ActionLink with parameters for action, controller & route values:

@Html.ActionLink("Some text","Action","Controller", new {id=1})

but instead of rendering the text with a link to the action, it renders a link with some weird URL that isn't what you want at all.

If you use intellisense to look at the overloads for ActionLink, you'll see that the overload you've got is interpreting new {id=1} as html attributes not as route values. You need the overload with one more parameter, which can be null:

@Html.ActionLink("Some text","Action","Controller", new {id=1}, null)

And then it works.

.Net Assembly Binding Redirect doesn’t work – because you have an Uppercase/lowercase error in config

Thanks to Eran Stiller for spotting the fact that assembly binding redirect fails—with no appropriate error message or clue as to the reason for failure—if you used PascalCasing instead of camelCasing casing in your config.
This fails:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
      <dependentAssembly>
        <assemblyIdentity name="Moq" Culture="neutral" PublicKeyToken="69f491c39445e920" />
        <bindingRedirect oldVersion="4.0.10827.0" newVersion="4.1.1309.1617" />
      </dependentAssembly>
    </assemblyBinding>
  </runtime>
</configuration>

because of incorrect case in the attributes Culture and PublicKeyToken. Make them camelCase like so:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
      <dependentAssembly>
        <assemblyIdentity name="Moq" culture="neutral" publicKeyToken="69f491c39445e920" />
        <bindingRedirect oldVersion="4.0.10827.0" newVersion="4.1.1309.1617" />
      </dependentAssembly>
    </assemblyBinding>
  </runtime>
</configuration>

and now it works.

Visual Studio 2012 Command Prompt Here

Something I always want with VS projects: The 'Command Line here' menu option within Visual Studio; and the 'Visual Studio Tools Command Line here' option in Windows explorer. So here they are for VS2012.

NB: that the Explorer right-click works when you right click on a folder icon but not, sadly, when you right click on empty space. If anyone has a solution for that I'll be glad to know.

Windows Explorer "VS2012 Command Prompt Here" Right-Click Menu Item

To add a Visual Studio 2012 Command Prompt Here to your Explorer Right-Click menu, save this as a .reg file to your desktop, and then run it:

Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Folder\shell\Command Line VS2012]
[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Folder\shell\Command Line VS2012\command]
@="cmd.exe /k echo on & pushd \"%1\" & \"C:\\Program Files\\Microsoft Visual Studio 11.0\\VC\\vcvarsall.bat\" x86"

If you have 64-bit Windows, you might want:

Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Folder\shell\Command Line VS2012]
[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Folder\shell\Command Line VS2012\command]
@="cmd.exe /k echo on & pushd \"%1\" & \"C:\\Program Files\\Microsoft Visual Studio 11.0\\VC\\vcvarsall.bat\" x64"

Visual Studio 2012 External Tools Command Prompt Here Menu Item

In visual studio choose TOOLS - External Tools. Press Add to add a new command with fields as follows:

Title: Command Line Here
Command: %COMSPEC%
Arguments: /K "%VS110COMNTOOLS%\VsDevCmd"
Initial Directory: $(ItemDir)

i.e.:

Visual Studio External Tools Command Line Here VS2012 Dialog Box

Sorted. You can add shortcut key to via TOOLS - Customize - Keyboard and setting a shortcut key for Tools.ExternalCommand{X} ... but you have to work out by counting what number your {X} is.
Visual Studio Customize Keyboard Tools.ExternalCommandX Dialog Box

WCF on .Net 4.x ReST Service with IIS 7 or 8 = HTTP Error 404.17

So my newly created WCF ReST service (or webHttp service, as MS more accurately like to call it) runs fine in Visual Studio 2012, using IIS Express. But when I switch to IIS proper (in my case, IIS8 on Windows 8) I get:

HTTP Error 404.17 - Not Found
The requested content appears to be script and will not be served by the static file handler.

Most so-far extant posts on how to fix this, refer to how to fix it for .Net 3 on Windows before Win8: Use "%WINDIR%\Microsoft.Net\Framework\v3.5\Windows Communication Foundation\ServiceModelReg.exe" to register or to repair registration of WCF components. (The other gotcha being, having the right AppPool settings for .Net version & for 32 vs. 64 bit).
This doesn't work for Windows 8 / .Net 4.X. Instead you must open the control panel "Turn Windows Features On or Off" and tick the box for Http activation:

Windows Features - Windows 8 - Net45 - WCF - Http Activation Tickbox
Windows Features - Windows 8 - Net45 - WCF - Http Activation

Which should fix the issue after a couple of minutes.
