TFS Merge goes funny unless you get latest version

Users of some other source control software are used to the fact that, any merge operation requires a workspace and if that workspace is on your local machine then you need to make sure it's up-to-date with the branch it is a workspace for before merging into that branch.

TFS is less up front about this, but it does still use your local workspace as a workspace for merge. Therefore:

Before doing a merge with TFS, get latest of the target branch. Then start your merge.

For the paranoid: get specific version -- Latest Version; and tick both 'overwrite' options.

How to Log WCF Message Bodies to Enterprise Library

Boy, was this painful. But there's not much too it when it works. There are several bits of config, 3 classes and some gotchas involved, as follows.

Config Sections

<system.serviceModel>
    <extensions>
      <behaviorExtensions>
        <!-- Gotcha: this element looks so easy but is a pain in the backside. 
             The type element has to *exactly* match the undocumented-and-fussier-than-anywhere-else-in-config required format
             If it has to change, the best way to do it is to delete the line and then use MS Service Configuration Tool to lookup the assembly and classname

The Gotchas

  1. Note this is a completely different route to what you'll find if you search for 'WCF message logging' What you'll find there is how to switch on WCF logging. Which logs everything - and I mean everything - except the message bodies.
  2. The typename in the behaviorExtensions section above is hard to type exactly as required
  3. The typename in the behaviorExtensions must specify an exact version number which is a pain when it changes
  4. Note that you can't do anything more sophisticated with the messages in the IClientMessageInspector because by design Messages are Read Once. If you want to extract the innards of the message, you have to copy it to a buffer, then and set the ref parameter to a new copy of the message.

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.
