Migrating to 64bit environment

Hi Andrew,

Can you please tell me which test runner are you using?
If you are running the tests via mstest than the problem is that mstest cannot run in 64 bit (it is built as 32 bit assembly).
You can solve that by using other test runner like nunit or xunit which can run in 64 bit.

Hi Ohad,

We are using MSTest to run our tests via Visual Studio and MSBuild.

When you say that MSTest cannot run in 64bit. Do you mean it cannot run Typemocked tests on a 64 bit environment? As MSTest can run our other unit tests which do not use Typemock?

Thanks.

Hi Ohad,

The problem is fixed now.

I had Typemock Isolator installed and not Isolator SP.

Within our project we were also referring to a 32bit version of the typemock dll's so I had to update the reference to use the 64bit Typemock dll's.

Thanks for your help.

Hi Andrew,

Glad you got it fixed :)
Just to make things clear - mstest cannot run in 64 bit context without any relation to Typemock. The mstest.exe binary is built as 32 bit binary and hence will not run in 64 bit.
You can check that by using the corflags.exe utility from visual studio command line:

corflags "c:Program Files (x86)Microsoft Visual Studio 9.0Common7IDEMSTest.exe"

You'll get the output:

Version : v2.0.50727
CLR Header: 2.5
PE : PE32
CorFlags : 11
ILONLY : 1
32BIT : 1 <== This tells us the executable is built as 32 bit.
Signed : 1

My guess is that the code you want to test is still running in 32 bit.

Thanks for clearing that up.
