Hi Jack,
| Can I write TC tests in Visual Studio 2010 in a language such as C#? |
Yes, you can do this by using the
Connected Applications feature of TestComplete.
| Can I import TC functions and have them appear as intellisense in Visual Studio? |
If you are using the Connected Applications approach, you implement all your functions in C#, so they will be available for Intellisense. For TestComplete objects like Process, Window, etc. the properties and methods will not be available for Intellisense.
| Can a TC project of tests be compiled into an exe or dll? |
No. But you can compile your Connected Application, though you will still need TestComplete or TestExecute to run tests in this app.
