Visual Studio creates unwanted directories for a new solution

So, all you want is to create a new visual studio project called MyProject in a SINGLE directory called MyProject. But behold, Visual Studio has created a million levels of directories called \MyProject\MyProject\MyProject for your project. And put it all all in source control to boot.
Simples:

  1. Specify your project name
  2. Specify the parent directory for MyProject
  3. Untick ‘Create Solution Directory

Visual Studio Create Project dialog highlighting the input fields for project name, existing parent directory and the unticked Create Solution Directory option

Visual Studio Create Project dialog


Voila.

Get the Moq Mock from a mock object

Update: See Vladimir’s comment below for the built in one-liner.

So there you in your code or possible your debugger and immediate window and you have a mock object and realise you want to change the setup but you didn’t keep a reference to the Mock<> …
So your first though is, no problem, you can cast your object to one of type Castle.Proxies.MyStronglyTypedProxyClass and voila you have access to the Mock property. Except that the compiler doesn’t recognise Castle.Proxies.MyStronglyTypedProxyClass as real class.
So then you try reflection to get hold of the Mock property. Which nearly works, but you get a System.Reflection.AmbiguousMatchException : Ambiguous match found. because there’s more than one property called Mock (one with and one without a generic parameter).
But this worked for me:

public static Mock<T> GetMockFromObject<T>(T mockedObject) where T : class
{
    PropertyInfo[] pis = mockedObject.GetType().GetProperties()
        .Where(
            p => p.PropertyType.Name == "Mock`1"
        ).ToArray();
    return pis.First().GetGetMethod().Invoke(mockedObject, null) as Mock<T>;
}

hope that helps.

I want to set a Windows Environment Variable for my whole user login session

Use setx to permanently set an environment variable

If you’ve used windows environment variables at all, you’ve probably wished you could set them in a command window for use in another program.
You can’t change the environment of an already-running program – the environment is copied when a program starts – but you can set environments values for your user session that will be picked up by any new programs you launch with setx:

setx myvariable thenewvalue

Much easier than right-clicking to get to My Computer properties.
setx /? will also tell you about setting permanent, machine-wide and remote machine environment values.

setx comes with Windows 7 or in the Windows Resouce Kit.

How to unset a variable set with setx

setx myvariable ""

It’s because you are trying to run 32 bit dlls on a 64 bit system. Fix it in IIS manager by changing the advanced settings on you application pool to enable 32 bit applications. Or create a new app pool specifically for them.

Alex James Brown has a nice picture: change app pool to 32 bit

There is a duplicate system.web.extensions/scripting/scriptResourceHandler section defined

Scenario:
You’ve been working with no problems probably in VS2008 on web app written on .net 2 or .net 3.5 or .net 3.5 sp1 and then you try running on a machine with windows 7 or vista running IIS7 and you get this error message…
Simples. It’s comes of running your .Net 2 (you did know that a .Net 3.5 app actually runs on .Net 2 didn’t you?) app under .Net 4. Fix it by changing the app pool for your web app to the pre-defined “Classic .Net App Pool”, which runs .Net framework 3
Run a dotNet 2 or dotNet 3 or dotNet 35 app under IIS7
