I have developed following code to generate dll files using Microsoft.CodeAnalysis.Emit library. The code successfully generates dll files for C# projects. However it doesn't successfully build Visual Basic projects. It throws lot of compiler errors for VB projects which build successfully using the VS IDE. Please see the errors thrown for a basic Windows application project. Is there any specific compiler options for VB projects? Please advice how to resolve this.
Microsoft.CodeAnalysis package version: 1.3.1
class Program
{
static void Main(string[] args)
{
const string UnitTestArtifactFolder = @"c:VSUnitTest";
string SolutionPath = @"C:BVBWinAppVBWinAppVBWinApp.vbproj";
CompileProject(SolutionPath, UnitTestArtifactFolder);
}
private static void CompileProject(string projectFilePath, string outputFolderPath)
{
using (var workspace = MSBuildWorkspace.Create())
{
var project = workspace.OpenProjectAsync(projectFilePath).Result;
Emit(project, outputFolderPath).Wait();
}
}
private static async Task Emit(Project project, string outputFolderPath)
{
Directory.CreateDirectory(outputFolderPath);
var options = GetCompilationOptions(project);
var compilation = await project.GetCompilationAsync();
compilation = compilation.WithOptions(options);
var outputFilePath = Path.Combine(outputFolderPath, Path.GetFileName(project.OutputFilePath));
var pdbFilePath = Path.ChangeExtension(outputFilePath, "pdb");
//LogInfo("Compiling the project...");
var compilationStatus = compilation.Emit(outputFilePath, pdbPath: pdbFilePath);
if (!compilationStatus.Success)
{
//LogError(compilationStatus.Diagnostics.First(k => k.WarningLevel == 0));
}
else
{
// LogInfo("Compilation successful.");
}
}
private static CompilationOptions GetCompilationOptions(Project project)
{
if (project.Language == "C#")
{
//LogInfo("Using C# Compilation Options");
return new CSharpCompilationOptions
(OutputKind.DynamicallyLinkedLibrary, optimizationLevel: OptimizationLevel.Debug);
}
else if (project.Language == "Visual Basic")
{
//LogInfo("Using Visual Basic Compilation Options");
return new VisualBasicCompilationOptions
(OutputKind.DynamicallyLinkedLibrary, optimizationLevel: OptimizationLevel.Debug);
}
else
{
//Throw if the language is other than C# or VB
throw new InvalidOperationException("Unsupported Language.");
}
}
}
