VB.NET — 146 Operations for AI Agents

This page is the canonical reference an AI coding agent uses to refactor, query, and analyze VB.NET code through the act MCP server. 146 operations available: 72 refactor, 18 query, 42 analysis, 14 verification. Each operation is callable from Claude Code, Cursor, Codex, OpenCode, or any MCP-compatible agent host. Click any operation for a stable anchor link suitable for citation.

Worked VB.NET examples

act101 parses VB.NET with the tree-sitter grammar and edits fields, statements, and class bodies as syntax nodes, so a modifier change, a syntax rewrite, or a generated member lands on the exact declaration it targets. It can add the ReadOnly modifier to a field declaration, enforcing that the field is only assigned in the constructor. It can convert a &-operator string concatenation into a $"...{expr}..." interpolated string. And it can generate a VB.NET auto-implemented property, adding a Public Property declaration with its own backing field to a class. Each example below is the verbatim output of the command shown, run against the file shown.

Make a field ReadOnly

counter.vb's Counter class declares _count as a plain, mutable field.

$ act refactor-lang vbnet_make_field_readonly --file counter.vb --params '{"field_name":"_count","line":2,"column":5}'

Before

Public Class Counter
    Private _count As Integer
End Class

After

Public Class Counter
    Private ReadOnly _count As Integer
End Class

ReadOnly is inserted after Private, so _count can only be assigned in the constructor.

Convert string concatenation to interpolation

greeter.vb's Greet method builds msg by concatenating a literal, name, and another literal with &.

$ act refactor-lang vbnet_convert_string_concatenation_to_interpolation --file greeter.vb --params '{"line":3,"column":1}'

Before

Public Class Greeter
    Public Sub Greet(name As String)
        Dim msg As String = "Hello, " & name & "!"
    End Sub
End Class

After

Public Class Greeter
    Public Sub Greet(name As String)
        Dim msg As String = $"Hello, {name}!"
    End Sub
End Class

The & chain becomes a single $"Hello, {name}!" interpolated string.

Generate an auto-implemented property

person.vb declares an empty Person class.

$ act refactor-lang vbnet_generate_auto_property --file person.vb --params '{"class_name":"Person","property_name":"Name","property_type":"String","line":2}'

Before

Public Class Person
End Class

After

Public Class Person
    Public Property Name As String
End Class

A Public Property Name As String declaration is added to the class body.
