RESOLVED DUPLICATE of bug 12951

Description Matt Ward 2014-07-19 05:40:50 UTC
To reproduce:

1) In Preferences/Projects/Build untick the "Build solution before running" option. This needs to be disabled.
2) Create a new C# console application.
3) Rebuild the entire solution.
4) Select Run/Start Debugging.

Expected result:

Application starts debugging.

Actual result:

The "Outdated Debug Information" dialog shows even though I just built the solution.

Debugging the code the DebugCommands.CheckBeforeDebugging method is called:

internal static CheckResult CheckBeforeDebugging (IBuildTarget target)
{
	if (IdeApp.Preferences.BuildBeforeExecuting)
		return CheckResult.BuildBeforeRun;
			
	if (!target.NeedsBuilding (IdeApp.Workspace.ActiveConfiguration))
		return CheckResult.Run;

The first if is skipped over since BuildBeforeExecuting is disabled.
The problem is that the target.NeedsBuilding returns true. Debugging this the target is an SolutionItem. Now the SolutionItem.NeedsBuilding always returns true.

[Obsolete ("This method will be removed in future releases")]
public bool NeedsBuilding (ConfigurationSelector configuration)
{
	return true;
}

Should DebugCommands be using another method which is not marked as obsolete?
It looks like MonoDevelop should be using the ProjectServiceExtension.GetNeedsBuilding (IBuildTarget item, ConfigurationSelector configuration) instead. That has an implementation in the Project class which checks the files in the project have been changed since the last build so it looks like it should not show the Outdated Debug Information dialog.
