• Visual Studio vs 2005 beta 2 setup fails

  When I try to setup vs 2005 beta 2, it says that it failed to setup visual studio itself after it gets to the end screen. The installation seems normal untill then because the vs 2005 even gets a checkmark next to it when on the install screen. The progress bar never moves when it is on vs 2005 though. I will post the error log when I can find it. Hello, I am getting the same kind of error  when installing Visual Studio 2005 Beta2. The comments before the "return value 3" are: MSI (s) (20:D8) [11:12:03:571]: Assembly Error:Function not defined in specified DLL. MSI (s) (20:D8) [11:12:03:571]: Note: 1: ...Show All

• Visual Studio Language Service handling TODO comment task items

  C#, VB.NET etc generate Task items from TODO, etc in comments. Is there an easy way to do this in the Managed Language Service Afterall, if you've got a Colorizer then it should automatically be able to identify comments and search them for the relevant tokens.

Could one of you please post your solution code for this, I've been unable to find a solution for this same issue myself. I've managed to add tasks to the Tasklist in the FDoIde but I hav ...Show All
