Node.js 20 actions are deprecated. The following actions are running on Node.js 20 and may not work as expected: dotnet/nbgv@v0.5.1, glennawatson/coverlet-msbuild@v2.1. Actions will be forced to run with Node.js 24 by default starting June 2nd, 2026. Node.js 20 will be removed from the runner on September 16th, 2026. Please check if updated versions of these actions are available that support Node.js 24. To opt into Node.js 24 now, set the FORCE_JAVASCRIPT_ACTIONS_TO_NODE24=true environment variable on the runner or in your workflow file. Once Node.js 24 becomes the default, you can temporarily opt out by setting ACTIONS_ALLOW_USE_UNSECURE_NODE_VERSION=true. For more information see: https://github.blog/changelog/2025-09-19-deprecation-of-node-20-on-github-actions-runners/

Possible null reference assignment.

Type 'SyntaxReceiver' can be sealed because it has no subtypes in its containing assembly and is not externally visible (https://learn.microsoft.com/dotnet/fundamentals/code-analysis/quality-rules/ca1852)

Prefer the generic overload 'Refit.Generator.WellKnownTypes.Get<T>()' instead of 'Refit.Generator.WellKnownTypes.Get(System.Type)' (https://learn.microsoft.com/dotnet/fundamentals/code-analysis/quality-rules/ca2263)

Unused field 'TypeParameterVariableName' (https://learn.microsoft.com/dotnet/fundamentals/code-analysis/quality-rules/ca1823)

The behavior of 'string.StartsWith(string)' could vary based on the current user's locale settings. Replace this call in 'Refit.Generator.Emitter.WriteMethodOpening(Refit.Generator.SourceWriter, Refit.Generator.MethodModel, bool, bool, bool)' with a call to 'string.StartsWith(string, System.StringComparison)'. (https://learn.microsoft.com/dotnet/fundamentals/code-analysis/quality-rules/ca1310)

Use 'StringBuilder.Append(char)' instead of 'StringBuilder.Append(string)' when the input is a constant unit string (https://learn.microsoft.com/dotnet/fundamentals/code-analysis/quality-rules/ca1834)

Method WriteRefitMethod passes 'ReturnTypeMetadata' as the paramName argument to a ArgumentOutOfRangeException constructor. Replace this argument with one of the method's parameter names. Note that the provided parameter name should have the exact casing as declared on the method. (https://learn.microsoft.com/dotnet/fundamentals/code-analysis/quality-rules/ca2208)

Provide a method named 'ToIndex' or 'FromInt32' as an alternate for operator op_Implicit (https://learn.microsoft.com/dotnet/fundamentals/code-analysis/quality-rules/ca2225)
