Error

I get this exception when trying to run the project.

An unhandled exception of type 'System.TypeLoadException' occurred in mscorlib.dll

Additional information: Inheritance security rules violated by type: 'System.Web.Http.SelfHost.HttpSelfHostConfiguration'. Derived types must either match the security accessibility of the base type or be less accessible.

Hi @starkemc thanks for reporting this. I'll take a look.

I solved it by using a newer version of System.Web.Http.SelfHost.dll (v5.0), which I downloaded from here

You can solve it by installilng https://www.nuget.org/packages/AspNetWebApi.SelfHost package.

Hi, forked this project recently and getting this error. I have tried what @alex440440 suggested. Still no luck

Please help, thanks.

Don't have the project now... As a general routine I'd suggest to:
1.Check runtime versions of all projects?
2. Run 'update-package -reinstall -project "ProjectName"' in the nuget command line for each project in the solution one by one.

The suggestion by Alex440440 solved it for me.

After using Self Host 5.2.3 package it works for me.
