How to have app.xaml & *.xaml files listed in .csproj when using upgrade assistant to migrate from 4.5 to 6.0

devarakonda ramakrishna 0

I am using Microsoft's upgrade assistant to migrate projects from 4.5 to 6.0. I am able to have ".cs" files included in the .csproj file by default by modifying the values of "EnableDefaultItems", "EnableDefaultCompileItems" to false in Microsoft.NET.Sdk.DefaultItems.targets. But for app.xaml & *.xaml files I am not able to find a similar setting that works. I tried modifying "EnableDefaultPageItems" & "EnableDefaultApplicationDefinition" to false in Microsoft.NET.Sdk.WindowsDesktop.targets but no luck.

Hi @devarakonda ramakrishna ，what project are you trying to upgrade? Does adding the following code work?

<ItemGroup> <Page Include="**/*.xaml" /> <ApplicationDefinition Include="App.xaml" /> </ItemGroup> <PropertyGroup> <EnableDefaultItems>false</EnableDefaultItems> </PropertyGroup>

Hi Jiale Xue,

Thanks for the response. Adding the above after migration works. But I want them to be added by default during migration which I am able to do for ".cs: files by setting "EnableDefaultItems", "EnableDefaultCompileItems" to false in Microsoft.NET.Sdk.DefaultItems.targets.

Thanks,

Ramakrishna

Try to create a new file named Directory.Build.props in the root of your project directory, and add the following code to the file:

<Project> <PropertyGroup> <EnableDefaultItems>false</EnableDefaultItems> </PropertyGroup> <ItemGroup> <Page Include="**/*.xaml" /> <ApplicationDefinition Include="App.xaml" /> </ItemGroup> </Project>

By the way, what project are you migrating? (WPF?)

No,

This is what I had in the new .csproj even after adding the suggested file.

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <TargetFramework>net7.0-windows</TargetFramework>
    <OutputType>WinExe</OutputType>
    <GenerateAssemblyInfo>false</GenerateAssemblyInfo>
    <UseWPF>true</UseWPF>
    <ImportWindowsDesktopTargets>true</ImportWindowsDesktopTargets>
  </PropertyGroup>
  <ItemGroup>
    <Compile Include="Class1.cs" />
    <Compile Include="Class2.cs" />
  </ItemGroup>
  <ItemGroup>
    <PackageReference Include="Microsoft.CSharp" Version="4.7.0" />
    <PackageReference Include="System.Data.DataSetExtensions" Version="4.5.0" />
    <PackageReference Include="Microsoft.DotNet.UpgradeAssistant.Extensions.Default.Analyzers" Version="0.4.421302">
      <PrivateAssets>all</PrivateAssets>
    </PackageReference>
    <PackageReference Include="Microsoft.Windows.Compatibility" Version="7.0.1" />
  </ItemGroup>
</Project>

The below are still missing from .csproj file

<Compile Include="UserControl1.xaml.cs">
      <DependentUpon>UserControl1.xaml</DependentUpon>
    </Compile>
    <Page Include="MainWindow.xaml">
      <Generator>MSBuild:Compile</Generator>
      <SubType>Designer</SubType>
    </Page>
    <Compile Include="App.xaml.cs">
      <DependentUpon>App.xaml</DependentUpon>
      <SubType>Code</SubType>
    </Compile>

Hi,@devarakonda ramakrishna. You could try to modify the settings in the Microsoft.NET.Sdk.WindowsDesktop.targets file to include App.xaml and *.xaml files in the .csproj file. And you can set the "EnableDefaultItem" and "EnableDefaultApplicationDefinition" properties to false.

Here's an example of what you could add to your .csproj file to include these settings. You could try to refer to it.

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <TargetFramework>net7.0-windows</TargetFramework>
    <OutputType>WinExe</OutputType>
    <GenerateAssemblyInfo>false</GenerateAssemblyInfo>
    <UseWPF>true</UseWPF>
    <ImportWindowsDesktopTargets>true</ImportWindowsDesktopTargets>
    <EnableDefaultItems>false</EnableDefaultItems>
    <EnableDefaultCompileItems>false</EnableDefaultCompileItems>
    <EnableDefaultPageItems>false</EnableDefaultPageItems>
    <EnableDefaultApplicationDefinition>false</EnableDefaultApplicationDefinition>
  </PropertyGroup>
  <ItemGroup>
    <Compile Include="Class1.cs" />
    <Compile Include="Class2.cs" />
    <Compile Include="UserControl1.xaml.cs">
      <DependentUpon>UserControl1.xaml</DependentUpon>
    </Compile>
    <Compile Include="App.xaml.cs">
      <DependentUpon>App.xaml</DependentUpon>
      <SubType>Code</SubType>
    </Compile>
  </ItemGroup>
  <ItemGroup>
    <Page Include="MainWindow.xaml">
      <Generator>MSBuild:Compile</Generator>
      <SubType>Designer</SubType>
    </Page>
  </ItemGroup>
  <ItemGroup>
    <ApplicationDefinition Include="App.xaml">
      <Generator>MSBuild:Compile</Generator>
      <SubType>Designer</SubType>
    </ApplicationDefinition>
  </ItemGroup>
  <ItemGroup>
    <None Include="App.config" />
  </ItemGroup>
  <ItemGroup>
    <PackageReference Include="Microsoft.CSharp" Version="4.7.0" />
    <PackageReference Include="System.Data.DataSetExtensions" Version="4.5.0" />
    <PackageReference Include="Microsoft.DotNet.UpgradeAssistant.Extensions.Default.Analyzers" Version="0.4.421302">
      <PrivateAssets>all</PrivateAssets>
    </PackageReference>
    <PackageReference Include="Microsoft.Windows.Compatibility" Version="7.0.1" />
  </ItemGroup>
</Project>

Hope this is helpful for you.

Hi Hui Liu,

Thanks for the response. Can you help me with what to add in Microsoft.NET.Sdk.WindowsDesktop.targets to include *.xaml & app.xaml

In Microsoft.NET.Sdk.WindowsDesktop.targets, I set EnableDefaultItems & EnableDefaultApplicationDefinition to false and added the below but still no result.

<ItemGroup> <Page Include="**/*.xaml" /> <ApplicationDefinition Include="App.xaml" /> </ItemGroup>

My requirement is simple, I want to restore all the compile includes as they were in the previous .csproj..

Thanks,

Ramakrishna
