Task type

Best practices

Description

Need to update the threading analyzers to match best practices.
https://github.com/microsoft/vs-threading/blob/main/docfx/analyzers/index.md

• Update VSTHR* rules in the editor config:

  microsoft-authentication-library-for-dotnet/.editorconfig

  Lines 201 to 244 in ab79751

  	dotnet_diagnostic.VSTHRD200.severity = error
  	# Use .ConfigureAwait(bool)
  	dotnet_diagnostic.VSTHRD111.severity = error
  	# Avoid async void methods
  	dotnet_diagnostic.VSTHRD100.severity = warning
  	# Critical Threading Rules
  	# Avoid legacy thread switching methods
  	dotnet_diagnostic.VSTHRD001.severity = warning
  	# Avoid problematic synchronous waits
  	dotnet_diagnostic.VSTHRD002.severity = none
  	# Avoid awaiting foreign Tasks
  	dotnet_diagnostic.VSTHRD003.severity = none
  	# Await SwitchToMainThreadAsync
  	dotnet_diagnostic.VSTHRD004.severity = error
  	# Invoke single-threaded types on Main thread
  	dotnet_diagnostic.VSTHRD010.severity = warning
  	# Use AsyncLazy<T>
  	dotnet_diagnostic.VSTHRD011.severity = none #error requires the use of Microsoft.VisualStudio.Threading to get access to the AsyncLazy<T> type
  	# Provide JoinableTaskFactory where allowed
  	dotnet_diagnostic.VSTHRD012.severity = warning
  	# Compiler warnings that trigger SDL
  	dotnet_diagnostic.CS0618.severity = error
  	# General Threading Rules
  	# VSTHRD103: Call async methods when in an async method
  	dotnet_diagnostic.VSTHRD103.severity = none
  	# VSTHRD105: use current context
  	dotnet_diagnostic.VSTHRD105.severity = none
  	# VSTHRD001: use JoinableTaskFactory (this is part of a different package - MSAL cannot use it)
  	dotnet_diagnostic.VSTHRD001.severity = none

• Remove this rule from tests .editorconfig:

  microsoft-authentication-library-for-dotnet/tests/.editorconfig

  Line 7 in ab79751

  dotnet_diagnostic.VSTHRD100.severity = none

• Suppress any other irrelevant rules in tests .editorconfig.
• Fix any errors or suppress them in the GlobalSuppressions file.
• Ignore all the rules for json folder.
