@hazzik Alex,

In the latest tests you added in PR #190, this one fails : C:\projects\delegatedecompiler\src\DelegateDecompiler.Tests\NestedExpressionsTests.cs:line 18

Here's the stacktrace

That is strange, because it does not fail for me... I'll check.

@magicmoux what SDKs/runtimes do you have?
