I have a problem when it comes to unit testing the leadtools RasterCodecs methods.
I have a simple test that tries to get information about a file that is not supported by leadtools. This should generate a RasterException with the RasterExceptionCode.FileFormat. This works alright but when I run this test on our build server the nunit process registers the following event in the event log.

Application: nunit-agent.exe
Framework Version: v4.0.30319
Description: The process was terminated due to an internal error in the .NET Runtime at IP 000007FD898236FC (000007FD89820000) with exit code 80131506.

(Stacktrace from testrunner shown below)

It seems that the test works alright but when the program that executes the tests tries to end the error occurs.

It would normally be a nunit issue but when I remove the call to codec.GetInformation or if I supply a file that Leadtools can load, then I don't get this error.

My suspicion is that the error that occurs in the RasterCodec class, don't dispose all resources used and when the process ends, cleanup fails to do its job.

I have tried the RasterCodec.Load method and it behaves the same.

Can you help me with this?

I am using Leadtools (FileVersion for 64 bit

The test itself
public void TryToLoadAnXmlFileInLeadtools() {
var path = Path.GetTempFileName();
using (var w = new StreamWriter(File.OpenWrite(path))) {
try {
using (var codec = new RasterCodecs()) {
using (var codecsImageInfo = codec.GetInformation(path, true)) {
if (codecsImageInfo != null) throw new ApplicationException("This should only happen on supported files");
} catch (RasterException ex) {
if (ex.Code == RasterExceptionCode.FileFormat) {
//we should end up here.
} finally {
The stacktrace from nunit shows

This problem would require more testing on our end to determine if it is a bug in the source or if perhaps something that is happening on your end. Would it be possible for you to provide a small sample project that duplicates this issue for us to test here? We do not need your whole solution just a simple one button forum that easily illustrates the problem, and any sample files that are required to duplicate the issue. Do not forget to clean the solution as we do not need any dlls.

You can send the sample project to support@leadtools.com with steps to duplicate the issue.

Thank you.
