Question

我正在尝试使用Roslyn解析VB.Net代码，但它不断抛出InvalidProgramException（Jit编译器遇到了限制......）。类似的代码与C＃完美配合。

这是我的代码：

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);

在最后一行抛出异常。

更新以下是堆栈跟踪：

Answer 1

此异常通常表示程序本身已损坏。如果您能够提供故障转储文件，请执行此操作。

另外，请验证您的程序集在某种程度上是否已损坏。我们发布的所有Roslyn二进制文件都经过数字签名，因此请检查您的Roslyn.Compilers.VisualBasic.dll是否具有有效签名。找到DLL，转到Windows资源管理器中的文件属性，数字签名选项卡，然后点击详细信息。确认您看到“签名没问题。”

Answer 2

事实证明，当我仅在我的网站上使用代码时会抛出异常，然后该网站在VisualStudio Development Server或IIS Express上运行。也通过TestDriven.net和Gallio运行它（可能只是旧版本）。代码运行良好，控制台应用程序或IIS已满。

我仍然认为这是一个错误，因为使用CSharp编译器的类似代码运行得很好。
