问题 I want to debug a program in Visual Studio 2008. The problem is that it exits if it doesn't get arguments.

问题 When a debugger is attached to a .NET process, it (usually) stops when an unhandled exception is thrown. However, this doesn't seem to work when you're in an async method. The scenarios I've tried before are listed in the following code: class Program { static void Main() { // Debugger stopps correctly Task.Run(() => SyncOp()); // Debugger doesn't stop Task.Run(async () => SyncOp()); // Debugger doesn't stop Task.Run((Func<Task>)AsyncTaskOp); // Debugger stops on "Wait()" with

I have installed VS 2015 RTM (nothing else) and I'm unable to debug any solution, not matter if it's an existing one or a brand new one (created with VS 2015 and compiled against .Net Framework 4.6), it only opens a new tab in VS which is called Break Mode with the following text: The application is in break mode Your app has entered a break state, but no code is executing that is supported by the selected debug engine (for e.g. only native runtime code is executing).

阅读更多关于 How to debug SQL Server T-SQL in Visual Studio 2012

问题 How does one debug a T-SQL stored procedure in a multi-tier application in Visual Studio 2012? To be clear, I want to set a breakpoint in a sproc in VS 2012, and hit it when the sproc is called from an ASP.NET WebForms app in the same debugging session. When following the same steps as for VS 2010, the breakpoints aren't hit inside the sproc. Debugging T-SQL in a sproc on a SQL Server 2008 R2 Express database works as expected in Visual Studio 2010. To be sure everything was enabled properly,

阅读更多关于 How to prevent Visual Studio from launching WcfSvcHost.exe while debugging?

I have a solution in Visual Studio 2008 which has multiple projects. One of the projects is a WCF project. Sometimes I just want to debug other projects, but when I press F5, Visual Studio has wcfsvchost.exe launched to host the WCF project even it is not "StartUp Project".

Anybody know better idea to prevent WCF project to be hosted in debugging mode? Go to WCF Options section in the property page of your WCF project and unselect

How to get non-current thread's stacktrace?

阅读更多关于 How to get non-current thread's stacktrace?

问题 It is possible to get stacktrace using System.Diagnostics.StackTrace, but thread has to be suspended. Suspend and Resume function are obsolete, so I expect that better way exists. 回答1: According to C# 3.0 in a Nutshell, this is one of the few situations where it is okay to call Suspend/Resume. 回答2: Here's what's worked for me so far: StackTrace GetStackTrace (Thread targetThread) { StackTrace stackTrace = null; var ready = new ManualResetEventSlim(); new Thread (() => { // Backstop to release
