    text
    copied!<p>I'm trying to parse VB.Net code using Roslyn, but it keeps throwing the <code>InvalidProgramException</code> (Jit compiler encountered a limitation..). A similar code works perfectly with C#.</p> <p>This is my code:</p> <pre class="lang-cs prettyprint-override"><code>var source = "Public Module Module1 \r\n Public Sub X() \r\n End Sub \r\n End Module"; var syntaxTree = Roslyn.Compilers.VisualBasic.SyntaxTree.ParseText(source); var compilation = Roslyn.Compilers.VisualBasic.Compilation.Create("MyCompilation", syntaxTrees: new[] {syntaxTree}); var semanticModel = compilation.GetSemanticModel(syntaxTree); </code></pre> <p>The exception is thrown on the last line.</p> <p><strong>Update</strong> Here's the stack trace:</p> <pre><code>System.InvalidProgramException: JIT Compiler encountered an internal limitation.
