Support multiple edmx files in the same project.

Support multiple edmx files in the same project.

• The Task need to be updated for multiple Input and Output files.
• The Target need to handle the multiple output files.

@malylemire1 I've been looking at adding some features to this package to cover scenarios like this one.
Unfortunately, there are some other improvements I need to do first, mainly around replacing the converted t4 templates code that currently generates the code with a CodeDomProvider / roslyn based version that is (mostly) language agnostic.
After that it will be much easier to adjust the behaviour of the task. The current version is a MVP, converting the old EF PowerTools feature and code.

Generally, I keep multiple DbContexts, their migrations and the edmx / views in separate projects, and then just include them into my main project, so the issue you are coming across doesn't happen.

You could manually call the custom MSBuild task multiple times from a custom target in your project, and pass in each view.

Untested:

<PropertyGroup>
	<CompileDependsOn>CustomEF6Views;$(CompileDependsOn)</CompileDependsOn>
</PropertyGroup>

<Target Name="CustomEF6Views">
	<MakeDir Directories="$(EntityFramework6GenerateViewsOutputDir)" ContinueOnError="true" />
	<ItemGroup>
		<_EntityViewCompile Remove="@(_EntityViewCompile)" />
		<_Temporary Remove="@(_Temporary)" />
		<_Temporary Include="EDMX\First.edmx">
			<CustomToolNamespace>MMBS.EntityFramework.First</CustomToolNamespace>
		</_Temporary>
	</ItemGroup>
	<C3D.MSBuild.Tools.EF6.Tasks.GenerateViews
	  SourceFiles="@(_Temporary)"
	  OutputDirectory="$(EntityFramework6GenerateViewsOutputDir)"
	  AssemblyName="$(AssemblyName)"
	  Language="$(Language)"
	  DefaultNamespace="$(RootNamespace)"
	  Debug="$(EntityFramework6GenerateViewsDebug)">
		<Output TaskParameter="OutputFile" ItemName="_EntityViewCompile" />
	</C3D.MSBuild.Tools.EF6.Tasks.GenerateViews>
	<ItemGroup>
		<_Temporary Remove="@(_Temporary)" />
		<_Temporary Include="EDMX\Second.edmx">
			<CustomToolNamespace>MMBS.EntityFramework.Second</CustomToolNamespace>
		</_Temporary>
	</ItemGroup>
	<C3D.MSBuild.Tools.EF6.Tasks.GenerateViews
	  SourceFiles="@(_Temporary)"
	  OutputDirectory="$(EntityFramework6GenerateViewsOutputDir)"
	  AssemblyName="$(AssemblyName)"
	  Language="$(Language)"
	  DefaultNamespace="$(RootNamespace)"
	  Debug="$(EntityFramework6GenerateViewsDebug)">
		<Output TaskParameter="OutputFile" ItemName="_EntityViewCompile" />
	</C3D.MSBuild.Tools.EF6.Tasks.GenerateViews>
	<ItemGroup>
		<Compile Include="@(_EntityViewCompile)" Condition="EXISTS('%(FullPath)')" />
		<FileWrites Include="@(_EntityViewCompile)" Condition="EXISTS('%(FullPath)')" />
	</ItemGroup>	
</Target>

Hi,

I have managed to make it work with a simple change

<EntityViews Include="EDMX\First.edmx">
      <CustomToolNamespace>MMBS.EntityFramework.First</CustomToolNamespace>
</EntityViews>
<EntityViews Include="EDMX\Second.edmx">
      <CustomToolNamespace>MMBS.EntityFramework.Second</CustomToolNamespace>
 </EntityViews>

<Target Name="EntityFramework6GenerateMultipleViewsTarget" BeforeTargets="BeforeCompile" Condition="'@(EntityViews)'!=''">
		<Message Text="EntityViews: %(EntityViews.Identity)" Importance="high" />
		<MakeDir Directories="$(EntityFramework6GenerateViewsOutputDir)" ContinueOnError="true" />
		<C3D.MSBuild.Tools.EF6.Tasks.GenerateViews
		  SourceFiles="@(EntityViews)"
		  OutputDirectory="$(EntityFramework6GenerateViewsOutputDir)"
		  AssemblyName="$(AssemblyName)"
		  Language="$(Language)"
		  DefaultNamespace="%(EntityViews.CustomToolNamespace)"
		  Debug="$(EntityFramework6GenerateViewsDebug)">
		  <Output TaskParameter="OutputFile" ItemName="_EntityViewCompile" />
		</C3D.MSBuild.Tools.EF6.Tasks.GenerateViews>
		<Message Text="%(_EntityViewCompile.Identity)" Importance="high" />
		<ItemGroup>
			<Compile Include="@(_EntityViewCompile)" Condition="EXISTS('%(FullPath)')" />
			<FileWrites Include="@(_EntityViewCompile)" Condition="EXISTS('%(FullPath)')" />
		</ItemGroup>
</Target>
