One advantage of this approach is that you're checking for a feature rather than a specific version, so in the future this code will continue to work so you effectively can future proof code.
Still it's pretty telling that we'll have to resort to this sort of chicanery just to figure out freaking version compatibility. Note that this in-place replacement is very different from the side by side installs of. NET 2. The two 3. Both versions ran under the. The 4. When you build a new project with Visual Studio , you can still target. But you are in effect referencing the same set of assemblies for both regardless which version you use. What's different is the compiler used to compile and link your code so compiling with.
Microsoft is trying hard to experiment with every possible permutation of releasing new versions of the. NET framework apparently. No two updates have been the same. Clearly updating to a full new version of. NET ie. Especially given that. To make things worse. NET that ships with Windows 8 so it will be with us for a long time to come unless Microsoft finally decides to push.
This is the same story we had when Vista launched with. NET 3. People had enough problems dealing with the confusing versioning of the 3. The same is likely to happen with. NET are unlikely to understand this nuance and end up thoroughly confused which version is installed. I suppose this is useful for some component vendors and strongly signed assemblies in corporate environments.
But seriously, if you are going to throw. I keep pushing Delphi on comments or forums, not because I have a weird bias but because it seems to be the best tool to use for Windows development and possibly Mobile and Apple as well with their new releases. Net is modeled after the productivity of Delphi and the C language seems to be primarily based on Java with a bit of Delphi sprinkled in Creator of Delphi created.
Net and C. If you compare. Net and Delphi - the primary difference is not productivity or language features but just the fact that. Net requires a runtime to run and Delphi does not. Runtime environments add on a ton of extra problems.
They add bloat, sluggish and slow startup times, a bazillion files, version issues that prevent your programs from running, complex deployment if you use 3rd party components, no support after X years, support can be yanked if security whole is found in the runtime leaving your program as just a pile of non-executable bits and bytes I can go on an on but I am at work and need to get things done.
I am baffled because native applications do not have issues listed above which runtime environments do, and if you can build a native application then why in the world would you build one that sits on a runtime? Seems like your just asking for problems. If someone responds to this, please be aware that I said "primary difference" is native. There are differences in the language but they are severely minor compared to Runtime vs Native.
The main point I am arguing is Native vs Runtime. Bill - if you are proficient in Delphi and have been doing it for years, then that's great. And like many other platforms that have faded from public view, while technical capable finding answers to problems and workarounds on places like StackOverflow, forums and blogs are lot less forthcoming than for current languages.
There is a big benefit in that respect to live with in one of the major eco-systems. Ad-free experience sponsored by:. Share on:. On this page:. NET - Part 1. Is this content useful to you?

With there being just additions and bug fixes an "upgrade install" probably made sense to Redmond.
Not justifying, only speculating. Lex Li March 14, NET 4 SP, instead of 4. Mike March 14, Recently the EF team got called out on it, and they seem to be in the process of getting their act together, recently it's simply been 4. NET itself is a mess, let's hope they rebase at 5.
Vasu March 14, There is no. That would be very confusing is'nt it. Michael K. Campbell March 14, NET Framework for the IT Pros and businesses pointy-haired bosses who will end up colliding with these 'stealth' versioning conflicts. They won't see this as an issue where Microsoft tried something new. Instead, they'll see this as merely being a case where.
NET apps are hard to support. So the next time developers want to use. NET for internal apps in companies where this was already a question of whether or not.
That, and it's NOT like people didn't complain about everything you've listed here prior to them launching this silliness upon the world. James March 15, Main Differences between ASP. NET 3. NET 4.
