FYI: How to use completion in non-Rider IDE

[PiotrZierhoffer]

You can take a look at https://github.com/betrusted-io/xous-core/tree/master/emulation#editing-renode-peripherals

It boils down to creating a specifc csproj that has proper references. I have not tested it, but you might be able to employ this approach if needed.

No tweaks to any .csproj files are needed. I managed to make IntelliSense work on VSCode with 3 things:

1. Make sure you have installed needed .NET SDKs etc, and mono. Also make sure that they are correctly added to your path so for example when you execute:

$ dotnet --info
.NET SDK (reflecting any global.json):
 Version:   5.0.202
 Commit:    db7cc87d51

Runtime Environment:
 OS Name:     ubuntu
 OS Version:  20.04
 OS Platform: Linux
 RID:         ubuntu.20.04-x64
 Base Path:   /usr/share/dotnet/sdk/5.0.202/

Host (useful for support):
  Version: 5.0.5
  Commit:  2f740adc14

.NET SDKs installed:
  3.1.408 [/usr/share/dotnet/sdk]
  5.0.202 [/usr/share/dotnet/sdk]

.NET runtimes installed:
  Microsoft.AspNetCore.App 3.1.14 [/usr/share/dotnet/shared/Microsoft.AspNetCore.App]
  Microsoft.AspNetCore.App 5.0.5 [/usr/share/dotnet/shared/Microsoft.AspNetCore.App]
  Microsoft.NETCore.App 3.1.14 [/usr/share/dotnet/shared/Microsoft.NETCore.App]
  Microsoft.NETCore.App 5.0.5 [/usr/share/dotnet/shared/Microsoft.NETCore.App]

To install additional .NET runtimes or SDKs:
  https://aka.ms/dotnet-download

You can see your .NET SDKs etc.
The same with mono:

$ mono --version
Mono JIT compiler version 6.12.0.122 (tarball Mon Feb 22 17:29:18 UTC 2021)

2. Install the C# extension and configure it.
   You have to tweak 2 settings in this extension:

Set it to use your global mono (in your User settings). By either adding this JSON line to your config:

"omnisharp.useGlobalMono": "always"

Or just toggle it in the settings:

3. Then make sure that your default project solution is set to Renode.sln. by either adding this JSON line to your local .vscode/settings.json:

"omnisharp.defaultLaunchSolution": "Renode.sln"

Or do it using VSCodes GUI for settings like so (just make sure that you are in the Workspace tab, otherwise Omnisharp will try to start every C# project you open in VSCode with a Renode.sln solution):

After following these 3 steps you should restart VSCode, after that it will probably prompt you about a few problems but you should ignore them, but also agree if its asking to "Restore" some missing dependencies, etc. Open a .cs file (for example: renode/src/Renode/Network/NetworkServer/NetworkServer.cs, for it to fully parse the renode project it needs a few minutes so just wait. When it finished your VSCode should look something like that, with references, authors, etc shown:

and when you hover over a function or ash VSCode to get you to its Definition etc it also should work:

I confirm this works. We'll consider how to put it in our docs, thanks
