Description Michael Bayne 2012-06-01 13:23:02 UTC
I have a project structure, that for other reasons, contains a symlink to a directory containing my resources. For example:

foo/images -> ../../somewhereelse/images

In the foo.csproj file, I reference resources in that images directory:

    <Content Include="images\alphalayertest.png" />

For yet other reasons, that symlink became invalid. When this happened, MonoDevelop began to completely fail to open my project. Failing with the non-useful error message:

  Error while trying to load the project '/Users/me/foo/foo.csproj': The directory name is invalid.

It would be great if it would report the name of the directory that was invalid, or even just load the project and mark all of the resources referenced through the invalid symlink as in error. Anything would be better than the obscure error above, that sent me off on a wild goose chase, trying to figure out what had changed and what the error message could possibly have meant.

Yes, I just got this, when updating my monomac project and deleting the monomac symlink and creating a new symlink, upon reloading the solution the projects that had monomac dll links aren't even loading in the editor.

Deleting the new symlink to monomac project directory at least lets the project that references monomac.dll load up.

This is monodevelop 3.0.05

This still happens in Xamarin Studio 5.8.2 (build 7).

I was able to reproduce this just trying to open the project from comment #2.
