I made a Incremental Source Generator:
<Project Sdk="Microsoft.NET.Sdk">
<PropertyGroup>
<TargetFramework>netstandard2.0</TargetFramework>
<IsRoslynComponent>true</IsRoslynComponent>
<LangVersion>latest</LangVersion>
</PropertyGroup>
<ItemGroup>
<PackageReference Include="Microsoft.CodeAnalysis" Version="4.2.0" />
<PackageReference Include="System.Text.Json" Version="6.0.0" />
</ItemGroup>
</Project>
It generates code that has an obvious syntax error
[Generator]
public class SourceGenerator : IIncrementalGenerator {
public void Initialize(IncrementalGeneratorInitializationContext context) {
context.RegisterSourceOutput(context.AdditionalTextsProvider, static (context, name) => {
string sourceCode = $#"
public class {"AAA"}{{
{{
}}
";
context.AddSource("AAA" + ".g.cs", sourceCode);
});
}
After building the solution for the first time and errors were expected. I restarted Visual Studio. I can see following code was generated:
public class AAA{
{
}
When viewing this AAA.g.cs, the text editor didn't highlight the fault of less closing braket.
Then I build the solution for the second time. It was succeeded. How can this be possible?
I've started migrating company owned application from UWP 10 to WinUI (on NET5) using upgrade-assistant tool. Give or take, the most conflicts are gone, but the the nasty one remains in .xaml files. The underlying code can't be source-generated due to missing namespace prefixes:
<ResourceDictionary
xmlns:xaml="clr-namespace:Windows.UI.Xaml;assembly=Windows"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="using:Ifs.Uma.UI.Controls">
<Style TargetType="local:Dialog">
<Setter Property="Background" Value="#FFEDEDED" />
</Style>
</ResourceDictionary>
I'm not sure if I'm missing some package references. Or if it's possible to just define them somewhere (XmlnsDefinitionAttribute is not available)? Is it even possible without going through hundreds of .xaml files and fixing all them manually or via find-replace?
For example, one of .csproj files with referenced packages below:

// 3. Add Pictures capability to your manifest (imho the easiest one to use)
// <Capabilities>

It all went fine, but resulted in a message that type <controls:ControlTemplate /> does not support direct content. This type is pretty much within every .xaml file. TemplateBinding and other binding types also not found. Perhaps, it's not the way to fix the issue, there might be an SDK missing or something.

The test runs without error, the types and methods are generated correctly.
But I absolutely hate writing tests in plain text, plus executing the tests like so doesnt yield test coverage or unit test cases, so I want to write a production test for the source generator. As per usual I create a .Run.Tests project and add the Rustic.DataEnumGen nuget project as an analyzer. Like so
<Project Sdk="Microsoft.NET.Sdk">
<PropertyGroup>
<TargetFrameworks>net48;net50;net60</TargetFrameworks>

using System;
using System.ComponentModel;

using Rustic;

Default = 0,
[DataEnum(typeof((int, int)))]
Minimum = 1,

}
public enum NoAttr
{
[Description("This is a description.")]
This,

}
[Flags]
public enum NoFlags : byte
{
Flag = 1 << 0,
Enums = 1 << 1,
Are = 1 << 2,
Not = 1 << 3,
Supported = 1 << 4,
}
[TestFixture]
public static class DataEnumRunTests
{
[Test]
public static void TestFactory()
{
DummyValue empty = default!;
DummyValue default = Default();
DummyValue min = Minimum((12, 43));
DummyValue min = Maximum((12, 43));
}
[Test]
public static void TestImplicitEnumCast()
{
Dummy default = Default();
Dummy min = Minimum((12, 43));
Dummy min = Maximum((12, 43));
}
}
}
This is the exact same code as in the previous test, but wrapped in a TestFixture instead of a console application. So I build the project with the analyzer, so that the DataEnumAttribute generated and then add the code above. But the code does not compile, because the type DataEnum or DataEnumAttribute does not exist.
First I thought that I needed to (I) ReferenceOutputAssembly, but that didn't change anything either, then I tried combinations of removing OutputItemType="Analyzer" and hoping that would result in the analyzer being called; nothing helped.
I conclude, that in this example the imported source generator, the very same that works in the first test case with the plain text compilation, is not executed before building the project, because if that was the case then type that is always added by the generator would be available in the project, and I would see some Rusic.*.g.cs in the obj/ directory. That is not the case.
So maybe the generator is not packed in the nuget package? As you can see the analyzer is being packed. Maybe I need to IncludeBuildOutput aswell? Nope not working either.
Now my question is why that is the case? Is there some specific thing, some specific attribute, I need to pay attention to when importing IIncrementalGenerator into a project compared to ISourceGenerator, because using an ISourceGenerator in a project works in the exact same way?
Is there anything else I might try to get the incremental source generator to work, or should I just revert to using a regular source generator?
References to good articles help as well, because there is effectively no doc to be found. When working I referenced most of Andrew Lock`s source generator related articles, specifically this one.
I tested this mit net 6.0.101 and a build of 6.0.2xx from like a week ago.
I'm setting up a new project with Entity Framework Core 5 and Postgres. All my project and my context are in the same project.
When adding a migration, I'm getting this error:

According to #bricelam in this issue the root of the problem lies here:
Changing BaseIntermediateOutputPath from its default when not running inside a
container breaks the EF Core tooling experience (*)
Since your BaseIntermediateOutputPath was changed from its default to obj/local when running outside the docker container, what you need to do is let the EF Core CLI know where to find that folder. You can accomplish that by using the --msbuildprojectextensionspath parameter. In your case, it would like like this (as suggested here):
dotnet ef migrations add NewMigration --msbuildprojectextensionspath obj/local
If you are still unable to make it work, you could follow the discussion in this other issue. In there, it was suggested that another possible fix is to change a bit your Directory.Build.props and *.csproj files so that the latter looks like the following:
<Project> <!-- Note: No Sdk="" here. -->
<PropertyGroup>
<!-- Don't use $(Configuration) since it isn't set yet. -->
<MSBuildProjectExtensionsPath>$(MSBuildProjectDirectory)\_intermediate_\</MSBuildProjectExtensionsPath>
</PropertyGroup>
<!-- MSBuildProjectExtensionsPath must be set before this gets imported. Directory.Build.props is too late. -->
<Import Project="Sdk.props" Sdk="Microsoft.NET.Sdk" />
<!-- (Project content goes here) -->
<Import Project="Sdk.targets" Sdk="Microsoft.NET.Sdk" />
</Project>
We are developing an Xamarin.Froms App and we got some problems with the video player the flowing code is working fine in debug or more specifically when shred runtime is enabled.

Using r8 needs a bit more config.
Create a new file in your Xamarin.Android app root named "r8.cfg".
In this file properties, set the Build Action to "ProguardConfiguration".
In this file, add the following lines:
-keep class org.videolan.** { *; }
-dontwarn org.videolan.**
