When i try to use ReSharper xUnit test runner, i'm encountering;

"Unit Test Runner failed to run tests, Unable to run xUnit tests - File not found:"D:\srcs\GitProjects..etc\bin\My.Tests.dll" Parameter name: assemblyFileName

Sorry for Turkish exception details, i couldn't change yet. Any idea about that? I searched a lot of forums and i couldn't find any useful stuff. Thanks in advance.
