.NET 3.5 [AssemblyInitialize] attribue, TestContext and NUnit test runner

Hello!

We are currently migrating our projects from .NET 2.0 to .NET 3.5 and found following issue:

To run tests on TeamCity we are using following entry in TeamCity proj file:

  <UsingTask TaskName="NUnit" AssemblyFile="$(teamcity_dotnet_nunitlauncher_msbuild_task)" />

Then we are running it using:

  <Target Name="CoreTest">
    <NUnitTeamCity Assemblies="$(OutDir)\Assembly1.dll;$(OutDir)\Assembly2.dll" />
  </Target>

We also use [AssemblyInitialize] attribute on method to run code before test run:

        [AssemblyInitialize]
        public static void StartUpMethodTestContext context)
        {
        }

On .NET 2.0 everything was fine - tests were running OK.

Since we migrated to 3.5 we are not able to run [AssemblyInitialize] method anymore from TeamCity. We are getting following error:

Object of type 'NUnit.Core.Builders.VstsTestFixture+NUnitTestContext' cannot be converted to type 'Microsoft.VisualStudio.TestTools.UnitTesting.TestContext'.

It seems that NUnit runner is passing NUnitTestContext object (but it should pass TestContext from MS Framework). As I wrote on .NET 2.0 everything was OK.

Is it possible to fix it or change anything in code to make it run?

Best Regards!
