Command Line Compiling Settings.settings using VBC

问题

To an earlier question of mine, invovling VBC and NAnt with WinForms, I have since come up with a better way of stating this.

Within vbproj file, you have the following:

<ItemGroup>
  <None Include="My Project\Settings.settings">
    <Generator>SettingsSingleFileGenerator</Generator>
    <CustomToolNamespace>My</CustomToolNamespace>
    <LastGenOutput>Settings.Designer.vb</LastGenOutput>
  </None>
</ItemGroup>
<ItemGroup>
  <Content Include="My Project\Application.myapp">
    <Generator>MyApplicationCodeGenerator</Generator>
    <LastGenOutput>Application.Designer.vb</LastGenOutput>
  </Content>
</ItemGroup>

When one runs build from within Visual Studio (Debug Verbosity set to Normal), one of the lines produces is:

Target CoreCompile:
    C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Vbc.exe ...

Which includes all of the settings required for vbc.exe to run. However, taking that string from Visual Studio, and running it directly on the command line yields:

... My Project\Settings.Designer.vb(67) : error BC30002: Type 'My.MySettings' is not defined.
        Friend ReadOnly Property Settings() As Global.My.MySettings
...\My Project\Settings.Designer.vb(69) : error BC30456: 'My' is not a member of '<Default>'.
                Return Global.My.MySettings.Default

How does one get the above Generators to run from a command line, or is there a call somewhere that will generate the correct temp files that are needed for vbc.exe to run the command string correctly?

回答1:

The problem with looking at the build string within visual studio is that it's not actually calling vbc.exe to build from visual studio. All builds in visual studio happen with the in-memory compiler instead of the command line compiler (true for C# as well).

The command that looks like vbc.exe ... is a generated string that isn't actually executed. If you want to find out the correct string to build your project run the following code from a visual studio command prompt.

msbuild /v:diag myproject.vbproj

This will produce an msbuild log file (it will be quite long so I suggest piping to a file). Once the build is completed search for vbc.exe within that file. It will have the actual command line needed to build your project.

I spent a while working on this today. I'd like to know a proper answer as to how to get the vbc compiler to work properly in regard to the "My" namespace, but I managed to get my NAnt script working using NAnt contrib (http://nantcontrib.sourceforge.net/).

NAnt contrib allows you to build using the .NET msbuild, which at least allowed me to set up automated builds, notifications, etc. It does not give quite the granular control I would like, but it serves its purpose.

The reference on this task is:

http://nantcontrib.sourceforge.net/release/latest/help/tasks/msbuild.html

And the pertinent snippet from my build script:

<target name="build" depends="clean">
     <msbuild project="ProjectName.vbproj" />
</target>

I've used NAnt quite a bit for CS applications, but this is the first for a VB.NET application.
