Now got this error @lightszero @erikzhang

Initialization method Neo.SmartContract.Framework.UnitTests.Services.Neo.IteratorTest.Init threw exception. System.TypeLoadException: Could not load type 'Neo.SmartContract.Framework.SmartContract' from assembly 'Neo.SmartContract.Framework, Version=3.0.0.0, Culture=neutral, PublicKeyToken=null' because the method 'Assert' has no implementation (no RVA)..

I can fix it removing the abstract keyword, but i am not sure if it will add a empty CALL with empty body after the call

d598207

[lightszero]

i will check it later.

[lightszero]

rosyln build in unittest can't extend a class with extern method.

   class abc:SmartContract // if SmartContract have extertn method  will got a build error.

@shargon
so we move Abort and Assert to another class will fix this.

[shargon]

Runtime?

[lightszero]

you can rename it.

[shargon]

@lightszero with empty body it's not possible to do that? discard the body if this method has OpCodeAttribute?

is possible,but we use extern in framework everywhere.so i think we should contine use extern for abort and assert

[shargon]

nice!!!

[erikzhang]

Test failed.

[shargon]

I will revert the last change because it will require GasLeft

[ProDog]

I have tested it passed.
Contract:

Invoke result:
for assert(true):

for assert(false):

for abort:

[ProDog]
