The CLR profiler I downloaded from here link text does not work for my app which is implemented using .NET 4.0. Is there a version for .NET 4.0? Thanks.
UPDATE: The CLR Profiler for .NET Framework 4 is now available here.
I couldn't find the CLR Profiler for .NET 4.0, but you should be able to use the older version if you set the environment variable: COMPLUS_ProfAPI_ProfilerCompatibilitySetting. For more information see this blog post.
Also note that as of .NET 4.0 the CLR outputs some more information to the Event Log to help you diagnose issues loading profilers. You can easily view these logs with the Event Viewer.
CLR Profile 4.0 can be downloaded here:

it looks like the installer is 64bit only, but you can unpack it using 7z and the 32bit version is inside the package.

I used to program in .NET 4.7.2 (and still do), but my High School uses .NET 6
Currently we have started using C# console in .NET 6
I don't want to update to .NET 6 because i would also have to change my Unity editor version to one that supports VS2022
Is it possible to open .NET 6 projects in .NET 4.7.2, or am i gonna have to update Unity and reinstall VS, while scouring every part of my C:// partition to clean up junk/leftovers? I am very tight on free space especially on C://
No, you can't (if you mean anything more then editing text, cause for this you can use even notepad). But depending on language features used potentially you can copy-paste code into a .NET Framework 4.7.2 project and compile it. Or not, cause at least some newer features are not supported by older framework version.
Also you don't need full blown VS upgrade. You can look into installing just the .NET 6 SDK and VS Code (which requires less space compared to VS 2022).
Though I hugely recommend to extend your disk.
I made the big mistake of taking some NuGet library updates today. It forced me to either roll back a week's worth of work or upgrade to ASP .NET Core 3.0. I hate to use stuff that's not production, but I didn't want to untangle the libraries either, so I upgraded. Then it forces me to retarget .NET Standard 2.1 libraries. Which I did.
My problem now is with the client UWP code. When I try to compile, I get:
error : Project '..\ClassLibrary1\ClassLibrary1.csproj' targets 'netstandard2.1'. It cannot be referenced by a project that targets 'UAP, Version=v10.0.10586'.
This happens even with a virgin UWP and .NET Standard 2.1 library. Any clues on how to make Visual Studio 2019 client code work with the latest upgrade?
All Windows 10 SDKs currently don't support .NET Standard 2.1.
Windows 10 19H2 is using the same SDK number as 19H1, so it is unlikely that it will support .NET Standard 2.1. (But I certainly hope it does.)
Microsoft hasn't made an official announcement, but Windows 10 20H1 is getting a meaningful SDK update, so it is likely that it will support it. And once that's the case, UWP apps will require 20H1 to run (so that will become the minimum supported version).
One of the big issue with this situation is that Entity Framework Core 3.0 requires .NET Standard 2.1, so it can't be used in UWP apps for now (Update: This issue is resolved with Entity Framework Core 3.1 supporting .NET Standard 2.0).
By the way, as an experiment, I was able to fork Entity Framework Core 3.0 (for SQLite) and make it compile on .NET Standard 2.0. I basically had to manually copy a few new APIs from .NET Core 3.0 (like IAsyncXXX). And it worked, so it is an option for people who really need it. Note that, I did not try it with the SQL Server provider.
Update: The UWP team is planning to enable UWP apps to use .NET 5 and that's when UWP will support .NET Standard 2.1 (and more). This could happen in 20H2 or 21H1.
UWP does not support .Net standard 2.1 yet. It only support till .Net standard 2.0 and that too from windows 1709 onwards.
If you look at the link for 2.1 it states
Platform Support
An upcoming version Universal Windows Platform
so it may be 19H2
UPDATE
Microsoft is going to release a new framework called WinUI 3, this is going to support UWP as well as Win32 based application model. WinUI 3 would support .Net 5 for both the platforms. WinUI 3 preview is going to be available in mid May 2020, with final release in late 2020. WinUI 3 would be supported on windows 10 1803+.
I have a few simple questions:
a) can I use mono on linux and osx to load the full .net framework like I would on windows by adding net46 to my project.json?
b) can I use mono as an alias like net46?
c) can I use mono with aspnet core 1.0 rtm projects on linux?
I have been looking at the dotnet docs, specifically the standard library and the table and the table with the platform support confuses me with the arrows and star under mono.
thanks
can I use mono on linux and osx to load the full .net framework like I would on windows by adding net46 to my project.json?
In theory, yes, that's exactly what you do: specify some version of net inside frameworks in your project.json and dotnet run will then use mono to run your application.
In practice, basic Hello World application works, but I'm not sure how well will more complicated applications work.
If you want to run dotnet build on the same machine, you will also need reference assemblies. The version I tested (mono 4.2.1) only contained reference assemblies up to .Net 4.5.1, so net451 works, but net46 doesn't.
can I use mono as an alias like net46?
I don't think you can, at least not without forking .Net Core SDK.
I don't understand why would you want to do that, but I believe doing so would require modifying DefaultFrameworkMappings in NuGet.Client.
can I use mono with aspnet core 1.0 rtm projects on linux?
I wasn't able to make a basic ASP.NET Core application run under mono. I don't know what the problem is, or how hard would it be to fix it. EDIT: I managed to work around the issue I encountered.
Mono is other thing. Yeah they developed mono like .net framework but you cannot use .net 4.6 on mono.
Read the following article. Click here
Micrsoft developed .net core a new framework to run .net on windows, linux, mac osx etc.
I would like to compile an executable using the F# 3.0 command-line compiler, and then run it under Mono.
The code starts to execute, but Mono dies almost immediately complaining it cannot load System.Core. Googling this suggests that I should be targeting .net 3.5, and not version 4. Further Googling suggests that the F# compiler used to take option --cli-version, but it no longer seems to accept that.
I am sure there is a way, seeing as if I were to use MSVC there would be somewhere I could click to set the desired CLR version.
What should I do please? Many thanks.
EDIT:
I have tried targeting .net 3.5 on a simpler project developed in the MSVC GUI. The executable then asked for FSharp.Core 2.0.0, and got further than before. The F# 3 compiler seems to come with a .net 2.0 core library, so I would expect that it is supposed to be able to generate code compatible with obsolete versions of the framework. The question this leaves is "if the GUI can do it, how do I do the same thing from the command line", please?
If you're using F# 3.0 there's no reason not to use .NET 4.0 by default (unless, of course, you need to interoperate with existing .NET 2.0 or 3.5 assemblies).
Which version of Mono are you running on? F# 3.0 requires Mono 2.10 or newer, but I'd strongly suggest you use Mono 3.0 or newer.
We have an MVC1.0 application that is compiled against and runs with .Net Framework 3.5.
The application was scanned for security and the scanning organisation reported
Microsoft ASP.NET ValidateRequest Filters Bypass Cross-Site Scripting
Vulnerability
https://community.qualys.com/docs/DOC-3495
What versions of Microsoft ASP.NET are vulnerable? Microsoft has
confirmed that ASP.NET versions 1 and 2 are both vulnerable.
Additionally, Qualys has confirmed that ASP.NET version 3 is also
vulnerable, as it includes the vulnerable component from version 2 by
default. We have tested this in our Labs and confirmed the exploit
works on a fully patched version 3.
We are already upgrading our application to MVC3, but that takes some more time to finish.
Is there any chance I can run and compile a MVC1.0 application against .NET 4.0?
This may arise compatibility issues, Even though there are very few dependencies over the .net framework.
You can refer the following posts.

From what I understand, anything that runs on .NET 3.5 should function and complile just fine in .NET 4.0, with perhaps some warnings about depreciated functions, but they will still work.
In case you are still curious/not comfortable, there are some tools available to help verify dependencies and other items such at NDepend
Best recommendation... try it! I can't think of any other reason than what Tommy mentioned about deprecated functions. Also, you can update most of your references with
Update-Package
without arguments.
If it compiles fine, do a quick test run over the views. If nothing seems broken, then it probably isn't.
