.net8.0正式版 升级 拿以前的项目测试aot编译踩坑笔记

之前测试失败，应该是虽然运行时是8.0但是平台没有指定8.0导致，
环境检查

项目指定环境,<TargetFramework>net8.0</TargetFramework>

    <PropertyGroup>
        <PublishAot>true</PublishAot>
        <TargetFramework>net8.0</TargetFramework>
        <Nullable>enable</Nullable>

        <OutputType>Exe</OutputType>
<JsonSerializerIsReflectionEnabledByDefault>true</JsonSerializerIsReflectionEnabledByDefault>
        <Configurations>xxx</Configurations>
    </PropertyGroup>

直接不aot,直接调试模式运行

 Reflection-based serialization has been disabled for this application. Either use the source generator APIs or explicitly configure the 'JsonSerializerOptions.TypeInfoResolver' property.

解决办法
msbuild配置加上

<JsonSerializerIsReflectionEnabledByDefault>true</JsonSerializerIsReflectionEnabledByDefault>

具体参考微软博客提供的信息如下:
https://devblogs.microsoft.com/dotnet/system-text-json-in-dotnet-8/

也就是说默认就禁用了反射默认值， 把它开启就可以解决。

我aot编译比较喜欢用的方式

dotnet publish 你的项目.csproj -r win-x64 -c CHANNEL

出现

Swashbuckle.AspNetCore.Filters.AddResponseHeadersFilter' could not be located
 for type 'Swashbuckle.AspNetCore.Filters.AddResponseHeadersFilter' could not be located. Ensure the type is concrete and all parameters of a public constructor are either registered as services or passed as arguments. Also ensure no extraneous arguments are provided.
         at Microsoft.Extensions.DependencyInjection.ActivatorUtilities.FindApplicableConstructor(Type, Type[], ConstructorInfo&, Nullable`1[]&) + 0xa1
         at Microsoft.Extensions.DependencyInjection.ActivatorUtilities.CreateInstance(IServiceProvider, Type, Object[]) + 0x447

这是我的提问，经过大佬的回答，我发现不是我想的那么完美

我visual studio新建项目 发现多了个native aot

和传统的，是做了一些改变，
dotnet publish直接搞定

也就是说要完美兼容，他的demo就是完美的，没有controller，也就是说controller就是mvc的那套，所以不支持的

他的demo的一些地方就是aot的源生成

而slimbuilder进行了特殊处理，更兼容一些。

参考
https://learn.microsoft.com/zh-cn/aspnet/core/fundamentals/native-aot?view=aspnetcore-8.0#aspnet-core-and-native-aot-compatibility image.png

所以正如我那提问 然后大佬说的，就算碰巧支持，那也是不分支持

不过呢，进行aot后变成单文件，普通人是无法进行逆向了，我认为目的已经达到了
另外没有controller，就要自行研究 怎么封装auth授权等东西了。
jwt目前是有了，但是没有以前那套还是差了点东西，先暂时观望吧
