I ran into the rare situation that I have to use static libraries in a project which were compiled with Visual Studio 2005.
As I do not want to get into trouble at runtime as mentioned in this post or here,
I think it's reasonable to use the original toolset.
As far as I have seen, using toolsets down to VS2008 is straightforward. For VS2005 this seems to be more challenging, only Daffodil might be an option.
Is there any chance to get the toolset v80 (VS2005) into the dropdown menu of VS2019 ?
After playing around, I don't know exactly understand how daffodil works or how a feasible approach looks like.
Maybe one could create wrapper-DLLs with a plain C-API and the help of VS2005. Using one IDE with various toolsets feels advantageously to me.
