asp.net mvc - After installing MVC3, I can't create or open projects for MVC2 on visual studio 2010 -

-

opening mvc2 projects makes "project not supported" error on visual studio, , can't find template creating new projects mvc2.

i undertand mvc2 new project template not desired after installing mvc3, support editing , maitaining mvc2 projects should still there.

in release notes states:

asp.net mvc 3 can installed side side asp.net mvc 2 on same computer, gives flexibility in choosing when upgrade asp.net mvc 2 application asp.net mvc 3

i know have mvc1, mvc2 , mvc3 dlls "side side" on gac, i'm still hoping visual studio error error in setup.

if not, ¿is possible upgrade project file , keep contents same, pointing mvc2 dll?

to answer own question after few attempts:

yes, possible upgrade project without altering mvc2. apply step 8 of manual migration procedure on release notes mvc3:

8- locate projecttypeguids element , replace {f85e285d-a4e0-4152-9332-ab1d724d3325} {e53f8fea-eae0-44a6-8774-ffd645390401}.

and reload project.

this should all.

the downside if other people working on project, need install mvc3 too, in order visual studio recognize new project guid.
