Simplify name of attach to process command

[richlander]

There should be no place where we say ".NET 5+ or .NET Core" in the Devkit UI. It's both because all the .NET Core versions are EOL but also because this phrasing is just unnecessary and confusing. It's also makes us look a bit silly.

[WardenGnaw]

The reasoning behind this naming is for the following:

• This action does not support attaching to a .NET Framework process, however the C# extension supports a debugger that supports debugging .NET Framework that produces portable PDBs.
• Although .NET Core is EOL, users may have projects still referencing it and the debugger has the capability of debugging them.
• This follows the same pattern we use in Visual Studio's Attach to Process

Let me know if we still should change the naming to just say Debug: Attach to a .NET process.

I think we should change it.

This comes down to a tradeoff:

• Use 100% accurate terms, or
• Use directly practical terms for most users

I'm in camp 2. We can rely on docs to explain support.

[gregg-miskelly]

I forget what failure looks like if you try and attach to a .NET Framework process. As long as we have some sort of reasonable failure message, I think it is okay to change it.

[WardenGnaw]

@gregg-miskelly This is the current error message: Failed to attach to process: The .NET Debugger can only attach to x64 processes.

[gregg-miskelly]

Can you try with an x64 .NET Framework process instead?

[gregg-miskelly]

Thanks. That is what I was afraid of. I personally think because of this we shouldn't name it "Debug: Attach to a .NET process" as there is almost no feedback what is wrong if you attach to a .NET Framework process.

@richlander What do you think of "Debug: Attach to a .NET (6+) process"?

[davidfowl]

Is there no way to detect and fail so we can call it .NET?

[gregg-miskelly]

I don't think we would want to error out in that case, since it is possible to host both .NET Framework and coreclr in the same process (not that this is a good idea). But we could warn I suppose.
