Proprietary Application Licensing with Tauri

[MattTheCuber]

My company is a developing proprietary software for profit using Tauri. Tauri's license supports this behavior under the MIT and Apache license. However, my questions lies with the Microsoft Visual Studio C++ Build Tools dependency.

The license for Microsoft Visual Studio C++ Build Tools is very complicated and confusing. It seems that they may be asking organizations to purchase a license to use the software. Since we are not directly using the build tools, does this requirement still fall on our company?

This indeed seems to be a tricky subject eg https://internals.rust-lang.org/t/visual-studio-build-tools-licensing/17097/5 / https://internals.rust-lang.org/t/use-lld-by-default-on-windows-to-mitigate-microsoft-c-build-tools-licencing-issues/16606/9 and it seems like it indeed requires getting the proper license if your project is not open source.

If all your rust crates support it, using the mingw toolchain instead of the msvc one may be worth to consider.
