Hi,
I downloaded the VS 2005 SDK last friday and I am testing out one of the
samples - an MFC sample.
I can compile it, but when I try to compile an add-in, I get:
--------------
The project file 'C:\ShapeAppSamples\ShapeAppBasicMFC\Sample
AddIns\CSharp\AppLevel\ShapeAppMFCAppAddIn.csproj' cannot be opened.
The project type is not supported by the installation.
--------------
What did I not install?

Signature
Thanks in advance,
Juan Dent, M.Sc.

Hi,
Judging by the project file extension, you didn't install C# :-)

Hi,
No, the thing was the project generated by VSTA had a strange Project Type
GUID and lacked Version and another tag. I corrected this and was able to
open and compile.
Thanks anyway...

Hi,
You need to remove the ProjectType element that has a GUID - its usually the
first entry under the first PropertyGroup.
Then you need to add these elements:
----------------
<ProductVersion>8.0.50727</ProductVersion>
<SchemaVersion>2.0</SchemaVersion>
----------------
just below the removed element.
Hope it helps!

I had this issue moving a web application to a new machine today. If
you are using a "Web Application" project type, it seems that the
"real" fix is to install:
WebApplicationProjectSetup.msi (for more info see:
http://webproject.scottgu.com/)
Apparently MS removed that from the default VS installation and you now
have to install it separately. Unbeknownst to me someone else had
already done this on the other machine.
Note that you may first need to install VS80-KB915364-X86-ENU.exe for
the WebApplicationProjectSetup.msi to install correctly.
