Steps to reproduce

Include a method with a Dictionary<string, string> parameter.

public class WithDictionaryArgs
{
    /// <summary>
    /// This is a method description
    /// </summary>
    /// <param name="args">Args description</param>
    /// <returns></returns>
    public string Method(Dictionary<string, string>? args = null) => string.Empty;
}

What is expected?

The documentation should be retrieved from XmlDocumentationProvider for the given method.

What is actually happening?

The XML path for methods with Dictionary arguments are generated incorrectly. The method name with a parameter of Dictionary<string, string> ends up with Dictionary{System.String],[System.String} rather than Dictionary{System.String,System.String}. This causes the XML element to not be found when calling XmlDocumentationProvider.GetDescription for the given method.
