xamarin.ios - Unable to load solution after upgrading to Xamarin Studio 6 -

i upgraded xamarin studio latest version, , unable load solution!

upon opening solution, below error displayed:

i have looked logs, , see following:

system.invalidoperationexception: bound project 

has seen similar error, or have solution?

thanks!

this error appear associated following xamarin bug report:

https://bugzilla.xamarin.com/show_bug.cgi?id=41565

if able try following workaround, should allow open project.

1. back solution
2. open each .csproj file associated extension (such watchkit or today)
3. find section "projecttypeguids"
4. remove key "feacfbd2-3405-455c-9665-78fe426c6842"
5. save file
6. attempt open solution

this should solve ios

this appears impact android projects contain bindings. example:

given test project (test.csproj) 2 projecttypesguid: {efba0ad7-5a72-4c68-af49-83d382785dcf} , {10368e6c-d01b-4462-8e8b-01fc667a7035} project fail load. because first id corresponds regular android project. second 1 android binding library project. problem can solved removing {efba0ad7-5a72-4c68-af49-83d382785dcf} guid .csproj

fixing issue android similar above. if project contains both projecttypesguid: {efba0ad7-5a72-4c68-af49-83d382785dcf} , {10368e6c-d01b-4462-8e8b-01fc667a7035} steps below

1. back solution up
2. open .csproj file
3. find section "projecttypeguids"
4. remove key "efba0ad7-5a72-4c68-af49-83d382785dcf"
5. save file
6. attempt open solution

thanks!

hope helps :)
