I'm customising a .csproj
project to run some custom tasks before the main build. However, I can't get the tasks to execute at all.
I uncommented the <Target Name="BeforeBuild" />
element in the .csproj
file and added a simple Message task, but when I build, the message doesn't appear in my output, so it seems the task isn't running. So this fragment does not output the message;
Listing 1: No Message Appears
<Target Name="BeforeBuild">
<Message Text="About to build ORM layer" Importance="normal" />
</Target>
However, if I screw with some of the attributes, I can get the .csproj
to fail to execute at all;
Listing 2: An MSBuild configuration error
<Target Name="BeforeBuild">
<Message Text="About to build ORM layer" XXImportance="normal" />
</Target>
Note the XXImportance
attribute. The build error I get is
My.csproj(83,46): error MSB4064: The "XXImportance" parameter is not supported by the "Message" task. Verify the parameter exists on the task, and it is a settable public instance property.
This suggests that the XML is being parsed, that the Message
class has been found, and that the class is being reflected over for the available properties.
Why would the task not execute?
I'm using the 3.5 framework.
UPDATE 1: On @Martin's advice, I tried to run MSBuild on the console, and got this error;
c:\path\to\my.csproj(74,11): error MSB4019: The imported
project "C:\Microsoft.CSharp.targets" was not found. Confirm
that the path in the <Import> declaration is correct, and that
the file exists on disk.
Line 74 reads;
<Import Project="$(MSBuildToolsPath)\Microsoft.CSharp.targets" />
UPDATE 2: I'm compiling in VS2008, which uses the C#3 compiler, but the project I'm compiling is a framework 2.0 project. When run from the command line (see UPDATE 1) the build seems to fail because there is a confusion as to where the Microsoft.CSharp.targets
file is specified.
