Can't Build UniGetUI

[mrixner]

I would love to see vcpkg support in UniGetUI (see issue #2146, not created by me) and was going to add the source code myself and create a pull request. A couple days ago I managed to get a build working, but now every time it just fails with a bunch of warnings about "Unsafe code may only appear if compiling with /unsafe". I don't know enough about C# to determine where this is coming from (it seems to be coming from the compiled object files, hence my inability to track it down with my limited knowledge) or how to properly fix this for this project; I'm probably doing something wrong but I'm not sure what. Can anyone help me to build UniGetUI locally?

I have the MSVC 2022 Build Tools installed with the .NET desktop build tools and Windows 10 SDK components (as well as some additional ones) installed, I have ran msbuild -t:restore to generate the NuGet packages as instructed by previous errors messages, and am building it via msbuild in the UniGetUI/src directory.

I am on Windows 11.

Output logs (the errors at the end):

This is weird...

Does compiling from Visual Studio work?

[mrixner]

I don't have Visual Studio installed, due to storage space issues. I will install the IDE as soon as I can and try; maybe it's an issue with the build tools.

[mrixner]

Actually, this first extra error looks like a configuration issue with my installation of Visual Studio.

I've uninstalled (repairing didn't work) both Visual Studio and the build tools and reinstalled only the Visual Studio package (not the build tools, unfortunately) with the .NET Desktop Development toolset installed. The configuration issues have all been resolved, however I am still receiving almost 200 errors when trying to build from the latest commit on main:

(For those with the same configuration problem: the VC directory was missing a Tools directory because the Tools directory was in MSBuild's in a different folder, and while Visual Studio wouldn't duplicate it because it was already installed somewhere, it was unable to find and use MSBuild's Tools directory. Personally, I think it's ridiculous that it wouldn't install because it's already installed but can't use the already installed version.)

Many /unsafe errors: (last error)

I've tried installing multiple different massive Visual Studio components and Googling solutions to the assembly errors, and so far nothing has helped. I really don't know what to do; are you willing / able to help?

[marticliment]

Do you have the AppSdk Runtime and the Windows Sdk installed?

[marticliment]

Wait, somehow I am also receiving this issue now. I swear this code did compile.

[marticliment]

You should be able to build with the latest commit: 301805a

[mrixner]

I'm getting plenty of warnings, but it compiles! Thank you so much!
