ReflectionTypeLoadException occurs when running multiple unit tests (Nunit 3)

[R-Lamberson]

Describe the bug

I am getting the following error during the startup configuration of my tests when I run multiple tests with VS2022 Test Explorer. The overall application is running dotnet 8.0

System.Reflection.ReflectionTypeLoadException : Unable to load one or more of the requested types.
Method 'get_Category' in type 'HandlebarsDotNet.Helpers.XsltHelpers' from assembly 'HandlebarsDotNet.Helpers.Xslt, Version=2.4.6.0, Culture=neutral, PublicKeyToken=00d131fae0c250bc' does not have an implementation.
----> System.TypeLoadException : Method 'get_Category' in type 'HandlebarsDotNet.Helpers.XsltHelpers' from assembly 'HandlebarsDotNet.Helpers.Xslt, Version=2.4.6.0, Culture=neutral, PublicKeyToken=00d131fae0c250bc' does not have an implementation.

The stack strack points back to an internal line of code which uses Reflection to GetTypes() which appears to be triggering this exception

when I run the tests individually I don't receive this error

I found the assembly within the WireMock.net packages and it appears that the 'HandlebarsDotNet.Helpers.XsltHelpers' does not have an implementation

Expected behavior:

All tests run without generating an exception

Test to reproduce

• 1 use Reflection GetTypes to retrieve assembly information during the startup of the application

• Wich version of WireMock are you using? Because latest WireMock depends on a newer version of Handlebars
• and make sure you do not import manually another nuget version of Handlebars related packages.

[R-Lamberson]

Sorry should have included that, version 1.8.13 of WireMock.net, and confirmed that I do not have a manually imported reference to HandleBars.Net

[StefH]

Can you clean your solution / delete all bin and obj folders.

Also delete all handlebars related nuget folders from your nuget cache folder.

Restore all packages.

Rebuild and test again.

[R-Lamberson]

I just did those steps and I end up with the same behavior.

[StefH]

Do you still get error like:
'HandlebarsDotNet.Helpers.Xslt, Version=2.4.6.0 ?

[R-Lamberson]

Yes

#1332

[StefH]

I found the issue.
New version will be released tomorrow.

[R-Lamberson]

I updated to version Wiremock.net 1.8.15, purged my bin and obj directories, cleaned my project and reran my tests and still hit the same behavior

test explorer error when running batch tests

nuget manager showing version upgrade, and class view showing the Handlebars.DotNet.Helpers.Xslt class view without exposed classes

[StefH]

Please wait until next version tomorrow.

Confirmed no longer getting an error from Handlebar Dotnet Helpers XSLT
