Implement proper assembly isolation to play nice with vscode-powershell

[o-l-a-v]

Is your feature request related to a problem? Please describe the problem.

According to vscode-powershell maintainers, Azure PowerShell (and I assume Microsoft.Graph too as I see similar problems with it) does not "implement assembly isolation correctly across the board".

• Unable to load Az modules - Assembly with same name is already loaded PowerShell/vscode-powershell#4727 (comment)

This can cause assembly conflict issues that vscode-powershell can't solve easily from their context.

I don't have deep knowledge about this, I just want my authoring experience where Microsoft owns every part of the stack fixed.

Here are some resources on how, using assembly load context (ALC):

Describe the solution you'd like.

Find out if anything can be done here to make Microsoft.Graph modules play nice with vscode-powershell.

Edit: Use AssemblyLoadContext for all assembly dependencies loaded by any Microsoft.Graph module.
