Various bugs running on large codebase

[bart-vmware]

Description

When running this analyzer on the codebase at https://github.com/SteeltoeOSS/Steeltoe, the fixers produce code that doesn't compile in several cases. After fixing them manually, various tests start to fail.

Complete minimal example reproducing the issue

• Clone the repo at https://github.com/SteeltoeOSS/Steeltoe
• Add the following to /shared-test.props:

  <ItemGroup>
    <PackageReference Include="FluentAssertions.Analyzers" Version="0.21.0" PrivateAssets="All" />
  </ItemGroup>
  <ItemGroup>
    <Using Include="FluentAssertions" />
    <Using Include="Xunit" />
  </ItemGroup>
  

• Set all analyzer rules of this package to Warning severity in Steeltoe.Debug.ruleset: Open src/Steeltoe.All in Visual Studio, expand the Dependencies/Analyzers/FluentAssertions.Analyzers node in project Common/Steeltoe.Common.Expression.Test, select all rules, and right-click > Set severity > Warning.
• Rebuild the Steeltoe.Common.Expression.Test project and use the fixers to update existing Xunit tests to FluentAssertions.

Expected behavior:

No broken code and no failing tests.

Actual behavior:

Some fixers don't actually change code; others produce code that doesn't compile. Some result in test failures.

Versions

• Which version of Fluent Assertions Analyzers are you using? v0.21.0 with FA v6.8.0
• Which .NET runtime and version are you targeting? .NET 6

Additional Information

I only tried running on the Steeltoe.Common.Expression.Test project. Running on the complete solution may surface additional issues.
