How to install .Net 6 on Windows 10?

I'm writing .Net code that needs a priority queue and would like to use this one:

Which says it needs .Net 6. Do I have that already installed?

reg query "HKLM\SOFTWARE\Microsoft\Net Framework Setup\NDP" /s

... many screenfuls of output that seem to be talking about versions 2 and 3, but the highest versions mentioned, seem to be

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Net Framework Setup\NDP\v4
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Net Framework Setup\NDP\v4\Client CBS REG_DWORD 0x1 Install REG_DWORD 0x1 InstallPath REG_SZ C:\Windows\Microsoft.NET\Framework64\v4.0.30319\ Release REG_DWORD 0x80ff4 Servicing REG_DWORD 0x0 TargetVersion REG_SZ 4.0.0 Version REG_SZ 4.8.04084
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Net Framework Setup\NDP\v4\Client\1033 CBS REG_DWORD 0x1 Install REG_DWORD 0x1 Release REG_DWORD 0x80ff4 Servicing REG_DWORD 0x0 TargetVersion REG_SZ 4.0.0 Version REG_SZ 4.8.04084
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Net Framework Setup\NDP\v4\Full CBS REG_DWORD 0x1 Install REG_DWORD 0x1 InstallPath REG_SZ C:\Windows\Microsoft.NET\Framework64\v4.0.30319\ Release REG_DWORD 0x80ff4 Servicing REG_DWORD 0x0 TargetVersion REG_SZ 4.0.0 Version REG_SZ 4.8.04084
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Net Framework Setup\NDP\v4\Full\1033 CBS REG_DWORD 0x1 Install REG_DWORD 0x1 Release REG_DWORD 0x80ff4 Servicing REG_DWORD 0x0 TargetVersion REG_SZ 4.0.0 Version REG_SZ 4.8.04084
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Net Framework Setup\NDP\v4.0 (Default) REG_SZ deprecated
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Net Framework Setup\NDP\v4.0\Client Install REG_DWORD 0x1 Version REG_SZ 4.0.0.0

... 4.x. And sure enough, when I try to compile code using PriorityQueue, the compiler will have none of it. Okay, Google leads me to what looks like an installer for .Net 6 Desktop Runtime:

Download, run, click through the various prompts, it claims successful completion.

And... Nothing has changed. Compiler gives the same error messages, and the attempt to check what versions are installed, gives exactly the same output as before.

What am I missing?

How to install .Net 6 on Windows 10?

You already did.

What am I missing?

The framework died at 4.8. What you want is now called .NET. .NET Core has jumped versions – going from 3.x to 5.x and then 6 and is now known as .NET

Press Win + R

Type cmd

On the command prompt, type dotnet --version

(if you've installed the SDK)

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\dotnet\Setup\InstalledVersions

(if you love regedit)
