• Built-in precedence in Expression Trees?

  - by jdk

  I'm unable to find the .NET FCL built-in concept of precedence to leverage while constructing Expression Trees. Ref System.Linq.Expressions Namespace. Is this something that must be handled manually in code, or is it somehow implicit and I'm not recognizing it? Maybe through helper methods or classes? I want to apply it to math operations to ensure 3 + 5 * 10 results in 53 instead of 80.

• ConfigurationErrorsException when running multiple instances due to file locking

  - by dr. evil

  I'm using My.Settings in my VB.NET application and when we run multiple instances rarely it's giving a ConfigurationErrorsException because the settings file locked by another instance. Is there anyway to fix this? This is happening during the OnShutdown process, also I'm not quite sure how can I catch that exception and handle it. Only thing I can think of is disabling onshutdown save and manually save it during the shutdown with extra retry + locking + exception handling.

• Moving files between Windows computers without creating network shares

  - by mavnn

  What's needed: To move several directories between two Windows 2008 servers on a regular basis. Due to security requirements, neither server is supposed to have network shares set up or extraneous software installed. What's available: Administrator access to both machines (including remote desktop access if that helps). A third machine with: Visual Studio 2010 Cygwin Bonus extras The script that does the rest of the work (apart from moving the files) is currently written in F#, but any .net/command line based solution would be fine.
