Some ideas

[Thieum]

That checklist is a great idea! Here are a few points I usually set in my own libraries/apps, some with retro-compatibility requirements, I mostly wonder if it could be useful outside of my context, so it's more an open discussion than an issue :)

• Enabling default code analyzers:

    <EnableNETAnalyzers>true</EnableNETAnalyzers>
    <AnalysisLevel>latest</AnalysisLevel>
    <AnalysisMode>AllEnabledByDefault</AnalysisMode>

Rationale: you want to fix or document any warning.

• Explicit Lang Version:

   <LangVersion>10</LangVersion>

Rationale: To avoid any conflict, and with latest version, you get extra help to modernize code.

• Restore Package with lock files:

  <RestorePackagesWithLockFile>true</RestorePackagesWithLockFile>

Rationale: best explained here: https://devblogs.microsoft.com/nuget/enable-repeatable-package-restores-using-a-lock-file/

• Explicit Root Namespace:

   <RootNamespace>FooBar</RootNamespace>

Rationale: to avoid an output rename that would conflict with existing code (more appropriate for exe than lib ?)

• Explicit value for EmbeddedResourceUseDependentUponConvention:

   <EmbeddedResourceUseDependentUponConvention>true</EmbeddedResourceUseDependentUponConvention>

Rationale: needed for multitarget to .net framework when using resx.

• Explicit CheckForOverflowUnderflow in Debug

   <CheckForOverflowUnderflow>true</CheckForOverflowUnderflow>

Rationale: default is false: https://docs.microsoft.com/en-us/dotnet/csharp/language-reference/compiler-options/language#checkforoverflowunderflow but still better safe than sorry, and add explicit bypass in code if needed

• Documentation File

   <DocumentationFile>..\bin\$(Configuration)\FooBar.xml</DocumentationFile>

Rationale: boring but useful for libraries.

-Treat Warning as Error in Release

   <TreatWarningsAsErrors>true</TreatWarningsAsErrors>

Rationale: effective way to keep the count low.

• Add a .editorconfig, and set what is needed to keep a consistent style.

Thanks for the ideas! There is definitely a few I'll add!
