Question

So I was looking at an open source’s csproj file and noticed this:

<ProjectExtensions>
   <VisualStudio>
       <FlavorProperties GUID="{FAE04EC0-301F-11D3-BF4B-00C04F79EFBC}">
         <HostingProcess disable="1" />
       </FlavorProperties>
   </VisualStudio>
<ProjectExtensions>

What does this do to a C# project and what is it telling visual studio to do? MSDN has this to say but I wasn’t entirely sure what they meant or where this would be applicable(MSDN MSBuild):

A project subtype can also modify the XML fragment before or after it delegates the call to an inner project subtype. The following example shows an excerpt from a project file, where a name of a file that contains properties specific to a project subtype, is passed to that project subtype

Any insight is appreciated!

Thanks!

Answer 1

That particular GUID (FAE04EC0-301F-11D3-BF4B-00C04F79EFBC) simply means it is a C# project. I established this by googling it, which is in general a good way to start to work out what the FlavorProperties GUIDs mean.

HostingProcess disable="1" refers to this:

Calls to certain APIs can be affected
by enabling the hosting process. In
these cases, it is necessary to
disable the hosting process to return
the correct results. To disable the
hosting process

• Open a project in Visual Studio.

• On the Project menu, click Properties.

• Click the Debug tab.

• Clear the Enable the Visual Studio hosting process check box.

When the hosting process is disabled,
several debugging features are
unavailable or experience decreased
performance. For more information, see
Debugging and the Hosting Process.

In general, when the hosting process
is disabled:

• The time needed to begin debugging .NET Framework applications increases.

• Design-time expression evaluation is unavailable.

• Partial trust debugging is unavailable.
