Okay, so this isn't strictly a programming question, but it is a programming-related question.
I have a C# winforms project that I am trying to add a reference to the System.Messaging dll.
However, when I add the reference (from the .net tab of the Add References dialog), it shows up with a yellow exclamation warning.
Right-clicking on other references will allow me to view them in the object browser. Right clicking on the System.Messaging reference will not.
Here's the kicker though... If I click on another reference and scroll through the list in the object browser, I can see the System.Messaging entry.
I tried a variety of things to fix this so far, including a forced reinstall of the dll in the GAC using gacutil, but it's still not working.
Does anyone have any suggestions as to how to fix this? If I need to provide more information, please leave the specific information request in the comments.
Note. The operating system is Vista.
I managed to find the solution after some creative googling.
On the project settings, there is a checkbox marked "Client-only framework subset".
Unchecking that checkbox did the trick.
