.WithBodyFromFile() + .WithTransformer(transformContentFromBodyAsFile: true) = empty string

[vitalyve]

Describe the bug

When .WithBodyFromFile(responseFilePath) is used in combination with .WithTransformer(transformContentFromBodyAsFile: true) the server returns empty string.

Expected behavior:

The server should return transformed contents of the file.

Test to reproduce

I've created a project with tests to demonstrate the problem. Please look at it.

Hi.
After some debugging of the WireMock.Net I've found that .WithTransformer(transformContentFromBodyAsFile: true) should be placed before .WithBodyFromFile() to be able to work as expected, but in examples form the Wiki it is placed after .WithBodyFromFile().
So, just need to update the article and the issue may be closed.
Anyway, thank you for the great project!

Yes. I just made a branch with your testcase.

And indeed the order is important. However from a user perspective it should always work.

I will check if I can update the code.

[StefH]

Changing the internal logic is some work.

Adding a check and throw exception is better for now.
