Downgrade Net Framework
Walda Caesar
I have a VM running Windows Server 2019 Standard. The O/S came out of the box with .NET Framework 4.8. I need to run some custom software that, according to the vendor, specifically requires 4.7.2. (I can verify that it's not working now, at least.) Since 4.8 was not the result of an upgrade or update, there is no installed update I can remove to downgrade. The Microsoft .NET doc says that it is not possible to uninstall the framework as of version 4. Other people say it is possible, but it breaks many of the essential O/S features and tools, making installing a different version extremely difficult. An hour of Google has turned up nothing more. Has anyone successfully gone from out-of-the-box 4.8 to 4.7.2 (or a similar path), and if so, would you please tell me how you did it?
As server 2019 originally came 4.7.2, you will need to rebuild the vm starting with an older version of the o/s. You will be limited in which service packs you can install, as one will do the upgrade.
No 3.05 is not normal, that should be an internal use beta BIOS. I imagine other users would be curious to find out what might be in that BIOS that other users do not have. When did you get your laptop? It might be that you just got 3.05 before they released it. Why would you want to downgrade?
I received my laptop in France on October 18th.
As I live in both Japan and France, but was not in France when it arrived, I had to wait for my parents to send it to me, and I started to use it only from this week-end.
It may not work however, it depends on if Framework implemented fuses to prevent such downgrading for security reasons. Like to prevent an attacker from downgrading to exploit a vulnerability. I would think it would just error out and not brick your device if that were the case
This is very interesting my Framework Laptop also shipped with 3.05, and I am guessing the one I ordered soon after and have yet to assemble also has 3.05 on it. Guess I will find out Friday when I set that one up. If I need to I will boot it up in a Windows Live envirnonment and update it/downgrade it, since I have also been experiencing weird thunderbolt issues with a dock that on several other machines has been very stable. I have also shot off a support request. If as suggested elsewhere that 3.05 is still in Beta, and that it was tested and found to have vulnerabilities this is pretty bad. We need an immediate response in this case not a delayed response. i.e. are downgrades supported? and where can we obtain the correct BIOS as this page does not offer any guidance on this scenario, nor any links to the existing BIOS version if is needed reflashed.
Completely understandable. I assumed I was on 3.04 as that was what is listed as the current stable BIOS. If I had done my due diligence and double checked I would have realized I was on 3.05 and then that would have been an avenue for additional troubleshooting. While many of the issues on the forums are more likely kernel or driver issues, thunderbolt issues tend to by and large be a firmware issue. Now I am wondering if any of my very minor issues are actually realted to this and not something else. So in short thank you.
My Batch 3 12th Gen also is running 3.05, I wonder if that is why I am having problems with a portable projector over HDMI that works with every other laptop that I have (11th Gen HP from work, and my older 4th Gen laptop).
The silence on the matter is a little telling. @Matt_Hartley since this is going to impact Linux users, any chance of an update regarding LVFS, or at least if it will be available directly as a cab file for local install without having to use a WIndows related workaround?
I upgraded php to 7.4 in a preparation to FreePBX 16 upgrade and that broke my FreePBX (15) GUI.
Then I decided to upgrade to 16 immediately but faced a php bug and upgraded my framework as suggested here Implode(): Passing glue string after array is deprecated. Swap the parameters
Now I cannot proceed with 15->16 upgrade because of the wrong framework installed. Please advise how to recover from this situation.
But, apparently this particular customer had some machines that somehow slipped through the cracks: they had Windows 10 2015 LTSB installed, which is based on the original RTM release known as 1507. We had overlooked the fact that this is the only LTSB release that does not support .NET 4.8, and that in fact a small number of machines we had supplied in the past, had this version of the OS installed, rather than either a Windows 7 Embedded, or a Windows 10 2016 LTSB or newer.
This is purely the language itself, the syntax, the keywords, the grammar. Different C++ compilers will support different versions and dialects of the programming language. Newer C++ compilers will generally support newer versions of the C++ standard. So the code you write will have to be within the limits of the language support of your compiler.
This layer consists of the interface between the programming language and the underlying machine and OS. This is where your APIs live, your headers, libraries, runtimes, frameworks, SDKs, middleware and that sort of thing. The code you write has to be within the limits of the various definitions (dataypes, functions, constants etc) of what is available to you in terms of programming interface and underlying OS, runtime libraries, drivers and such.
At the lowest level we have the actual hardware: the CPU, memory and related devices that make up a working system. A CPU implements a specific instructionset. Usually the CPU will be a certain revision of a family of CPUs, which use the same basic instructionset, but with different versions, revisions and extensions available. Your code will have to be within the limits of the instructions that your hardware supports.
Commonly, .NET is referenced by a single version number, such as .NET 4.6.2. However, there is more to it than meets the eye. In fact, the .NET environment has basically the same three layers as the native C++ stack described above:
In .NET parlance, such a machine is known as a Common Language Runtime. There are essentially 4 different CLRs in the classic .NET world (disregarding the .NET Core branches), each supporting one or more versions of the .NET Framework:
But in general it can also hold for your own code: Sometimes you need more than what the standard .NET Framework supplies, so you call native functions directly from your .NET environment (known as Platform Invoke or P/Invoke). Or indirectly: you are using a third-party .NET assembly which calls native code internally.
Obviously the achilles heel of such a system is that you depend on the repositories for the availability of packages. Entire repositories can go down, and older packages may get removed as they are no longer supported. So you may run into the situation that you can no longer build older projects, because the NuGet packages you require can no longer be downloaded.
Another problem that is related to NuGet packages is that each package has minimum requirements for the .NET version. In the case that you want to downgrade the .NET version, you may have to also downgrade the versions of certain NuGet packages to versions that are compatible with the lower .NET version.
As it turned out, I only ran into one problem when I downgraded all projects to .NET 4.6.2. And that was a NuGet package: NAudio.WinForms. The 2.x version requires at least .NET 4.7.2. There is no 1.x version of it. Why not? Well, NAudio used to be a single NuGet package, which included everything. For 2.x, it was split up in a number of sub-packages, of which NAudio.WinForms is one. The mess here is that the only sub-package that has the .NET 4.7.2 requirement is NAudio.WinForms. All the other 2.x packages target the .NET Standard 2.0, which includes .NET 4.5 and higher, so they work with .NET 4.6.2 out-of-the-box.
So, one way to get the code to work is to rework all the NuGet package references back to the old 1.x layout. However, NAudio is open source, so there is another possible way: modify it to work with .NET 4.6.2 and build it myself.
Well yes, this fix turned out to be relatively painless. So painless in fact, that I questioned why we even moved to .NET 4.8 at all? Although I suppose NAudio already answers that question more or less: Using a recent .NET version gives you access to certain libraries that you would otherwise be locked out of, or at least, would require you to go off the beaten path.
and if I want to use ESP-IDF current version from
GitHub - espressif/esp-idf: Espressif IoT Development Framework. Official development framework for Espressif SoCs. lastest dev. or lastest stable version( 3.1-beta1),
how to config them?
Not a great idea. The globally-installed CLI is designed to interoperate with any number of projects using different framework versions, so it is the absolute last thing you want to be downgrading. All that should concern you is the stuff declared in the package.json of your project directory.
I will echo the statements of others and tell you to play only the current version of the game, regardless of platform.
If you are unsure which version of the game you are playing, start the game, open the Menu (Esc) and select the SYSTEM tab. On the lower left of the display is the version number.
Hi. Based on your mods setup. Go and check them. For example, if you are using some .NET Script Framework based mods they are not going to work on 1.6+ because .net script framework (don't missread SCRIPT in its name, its a mod from nexusmods) authors are not going to update it to 1.6+ and you will need to search for an alternative mod (if it exists).
Ok, so I'm loving Maui, been using it a few months - fully appreciate it's still in "Preview", but started a greenfield project a couple of months ago, and it's going to evolve over the next few years. It made little sense using Xamarin, as we'd end up using a legacy framework before we've even released. Also, we have a growing library of Blazor components for our web application, and the mobile Application has quite a bit of crossover, so building the mobile app in Blazor seemed like a logical step. As the new BlazorWebView control which ships with Maui seems perfect for us, we've been building our app using Maui. Where I'm disappointed is that Maui still hasn't shipped to release (despite first quarter 2022 being it's target).
