With V1.1 of the Framework shipping

I though i'd post a couple of links I have found useful..

DennisAn wrote a great whitepaper on how to target different runtime
versions... href="http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnnetdep/html/sidexsidenet.asp">http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnnetdep/html/sidexsidenet.asp

And if you want to know the details of what is the breaking changes in V1.1
you can check out this list:

This list we generated from beta customers, our own testing and our own "by
design" changes:

Should we have a contest to see if who can find a breaking change not
listed?  😉

Hope that helps!

  1. In V1.1, doubles preserve leading zeros. In V1.0, they don’t. I think that counts as a breaking change.

    Shipping? Where? It’s not on MSDN downloads. VS.net 2003 hasnt shipped.
    Yeah, it’s in Win2k3, but it sure as hell isnt available outside of that.

    The new validateRequest setting was mentioned. If not set for a page (or application) you receive the following:

    A potentially dangerous Request.Form value was detected from the client (–Snippet of offending post presented here–).
    Description: Request Validation has detected a potentially dangerous client input value, and processing of the request has been aborted. This value may indicate an attempt to compromise the security of your application, such as a cross-site scripting attack. You can disable request validation by setting validateRequest=false in the Page directive or in the configuration section. However, it is strongly recommended that your application explicitly check all inputs in this case.

    V1.1 still has the "metric bug" in System.Windows.Forms.PageSetupDialog on PCs with metric System values. It reudces the margin values by a factor of 2.54. Is this a known bug, anyway? Does someone take care of that ?
