"Key 'program' is not set to launch configuration and /or is not a string"

Hi,

I am using Visual Studio 2022 (Windows) Version 17.6.3 with rust-analyzer.vs v2.0.154.

I open one of the rust files, click on run or debug I get this error.

thanks. which error?

please use https://www.screentogif.com/ to show the repro.

I had a similar problem with vscode and it added the launch configuration automatically.

[parthopdas]

thank you for the repro. it makes sense now.

so i'll have to disable setting anything other than cargo.toml or an example rs from the "currently selected document list". mainly because a rust project may have multiple .rs files and those are not really "startup projects".

in this case do you need to select main.rs for any specific reason? could you not select the contain toml file or the containing project from the select target drop down.

cargo.toml file is not on this list, selecting Exe works or selecting cargo.toml from solution explorer, right click/debug will work but these are not the default behaviors, In c# projects we are used to start debuging from the startup project file.

Probably customizing the error message to hint on what to do, instead of a cryptic message would help a lot.

[parthopdas]

customizing the error message is a good idea. it will be in the next release

I had the same issue. Setting the startup to be the projects Cargo.toml gets a little further, but now I get a very generic
