4.0 -> 4.5: how likely that existing working code will break? RRS feed

  • General discussion

  • We have a large application using various .NET technologies (inc. ASP.NET/Ajax/WCF/Linq-to-SQL) that currently builds on a machine with only .NET 4.0 installed.

    I've seen quite a few posts that indicate that upgrading to .NET 4.5 (which I assume would upgrade the C# compiler too) could introduce changes in application behaviour, and potentially even compilation failures (though I'm less worried about those as they're easy enough to spot!).

    Any users here with any experiences (positive or negative) trying to do this?

  • Hi Dylan,

    Welcome to the MSDN Forum.

    Based on your description, it seems that you didn't look for a specific solution, so I changed this thread type to discussion for more opening insights.


    Best regards,
