• 【FastDeploy版本】： fastdeploy-win-x64-gpu-1.0.4
• 【编译命令】通过cmake .. -G "Visual Studio 16 2019" -A x64 -DENABLE_ORT_BACKEND=ON -DENABLE_PADDLE_BACKEND=ON -DENABLE_OPENVINO_BACKEND=ON -DENABLE_VISION=ON -DWITH_GPU=ON -DENABLE_TEXT=ON -DWITH_CAPI=ON -DWITH_CSHARPAPI=ON -DCMAKE_INSTALL_PREFIX="D:\Paddle\compiled_fastdeploy_CUDA11_2" -DCUDA_DIRECTORY="C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v11.2" -DTRT_DIRECTORY="E:\work\tools\TensorRT-8.5.2.2.Windows10.x86_64.cuda-11.8.cudnn8.6\TensorRT-8.5.2.2"编译好了C#API
• 通过cmake .. -G "Visual Studio 16 2019" -A x64 -DFASTDEPLOY_INSTALL_DIR=E:\work\tools\fastdeploy-win-x64-gpu-1.0.4 -DCUDA_DIRECTORY="C:/Program Files/NVIDIA GPU Computing Toolkit/CUDA/v11.2"编译infer.cs,生成了infer_demo.sln,
• 【系统平台】: Windows x64(Windows10)
• 【硬件】： 说明具体硬件型号，如 Nvidia GPU 3060， CUDA 11.2 CUDNN 8.1
• 【编译语言】： C++

问题日志及出现问题的操作流程

cmakelist.txt 修改为

PROJECT(infer_demo CSharp)
CMAKE_MINIMUM_REQUIRED (VERSION 3.10)

Set the C# language version (defaults to 3.0 if not set).

set(CMAKE_CSharp_FLAGS "/langversion:10")
set(CMAKE_DOTNET_TARGET_FRAMEWORK "net6.0")
set(CMAKE_DOTNET_SDK "Microsoft.NET.Sdk")

指定下载解压后的fastdeploy库路径

#option(FASTDEPLOY_INSTALL_DIR "Path of downloaded fastdeploy sdk.")
option(FASTDEPLOY_INSTALL_DIR "E:\work\tools\fastdeploy-win-x64-gpu-1.0.4\")
include(${FASTDEPLOY_INSTALL_DIR}/FastDeployCSharp.cmake)
add_executable(infer_demo ${PROJECT_SOURCE_DIR}/infer.cs)
set_property(TARGET infer_demo PROPERTY VS_DOTNET_REFERENCES ${FASTDEPLOY_DOTNET_REFERENCES})
set_property(TARGET infer_demo PROPERTY VS_PACKAGE_REFERENCES ${FASTDEPLOY_PACKAGE_REFERENCES})

我是VS2019环境，net6.0，不支持，改net5.0也不行

Start with the CMakeLists.txt, infer.cs, generated infer_demo.csproj, and the FastDeployCSharp.cmake referenced in the issue. Run NuGet restore for the paddleseg CPU/GPU C# example and trace the target-framework compatibility errors; done means the project restores and the infer.cs example builds under the documented Visual Studio setup.
