MSB3971 on app which was building properly prior to March 2023 update, and Windows 11 Update

[simondugre]

First time I write in Github but, sounds like there's a problem with this version.

DESCRIPTION

Since yesterday update, I'm unable to create or either open any of my projects built in .NET6. I even tried to create a new project from scratch and instantly get the same issue. All of them are returning a;

Error MSB3971 The reference assemblies for ".NETFramework,Version=v6.0" were not found. You might be using an older .NET SDK to target .NET 5.0 or higher. Update Visual Studio and/or your .NET SDK. testapp C:\Program Files\Microsoft Visual Studio\2022\Community\MSBuild\Current\Bin\amd64\Microsoft.Common.CurrentVersion.targets

When I get a check on project properties, framework remains empty;

Must say that I'm running on Windows 11, which also had an update yesterday, maybe is it related?
Also, I just noticed that, for an unknown reason, I'm wondering why is it looking for a "AMD64" knowing that I'm having an Intel Core VPRO (i9) ...

What I've tried so far;

• Update Visual Studio
• Updating component of it and ensure .NET6 features are donwload and installed
• Reinstall all SDKs from MS official download sites
• Even tried to reinstall VStudio.

I guess my next step is to going back to Windows 10... ?

for the AMD64 question is because AMD64 is x64 which your processor is using. Can you share your csproj? When you open command prompt and type dotnet --info what does it return?

Btw issue looks like you just need to install SDK: https://dotnet.microsoft.com/en-us/download but can't tell for sure without csproj/dotnet --info

As because I have a deployment planned tomorow (Friday), I had to act quickly so I formated my whole computer. Which has solved my problem... But just to let you know, I do have installed the SDK from the link you refered somewhere in my hundred tries to make it works.

Now, because I haven't changed anything in my csproj, here it is;
