弄清楚为什么 Microsoft.Build.Evaluation.Project.Build() 返回 false

Question

I'm trying to build C# projects using .csproj files. For this I'm using the following code:

Microsoft.Build.Evaluation.Project project = new Microsoft.Build.EvaluationProject(projectFile);
bool success = project.Build();

But not all projects are build and for some I get false as the result of project.Build() . Any ideas how to understand what is going wrong?

Or maybe anyone can suggest an alternative way to compile projects using .csproj files?

You need to add an ILogger to the Build method as a parameter. I suggest implementing one as the MSDN article suggests . Just copy paste their code, add any missing references and you'll be fine.

Then you can call Build as follows:

Microsoft.Build.Evaluation.Project project = new Microsoft.Build.Evaluation.Project(projectFile);
BasicFileLogger logger = new BasicFileLogger();
logger.Parameters = logFilePath;
logger.Verbosity = LoggerVerbosity.Normal; //Increase it if you don't get enough data
bool success = project.Build(logger);

The example logger will write all data that you would see during a normal build to the file at logFilePath . Based on that you should be able to discern the issue.
