It appears that Attributes.dll must be in the nunit binary directory in order for the test binaries which depend on it to be loaded. Otherwise, all nunit front ends blow up with the above exception. On the other hand, with Attributes.dll in the nunit binary directory, only nunit-console-x86.exe blows up.
I understand what you are saying and I agree that the behavior you are describing should be how it works. I didn't expect to have to copy that file there. However, it is not what I am seeing, hence the bug. Also, the behavior is not consistent between nunit-console.exe and nunit- console-x86.exe (nunit-x86.exe seems to be able to deal with this [with Attributes.dll in the nunit binary directory none the less] appropriately). I put together the attached bare bones solution to illustrate a reproducible test case. Do you think it's worth taking a look? -- You received this bug notification because you are a member of NUnit Developers, which is subscribed to NUnit V2. https://bugs.launchpad.net/bugs/796880 Title: nunit-concole-x86 unable to load external library on which test suite depends on Status in NUnit V2 Test Framework: Invalid Bug description: Version: 2.5.10.11092 OS: Win7 64bit Mode: 32bit Environment: Solution with two projects: 1.
