here is a sample code:
using System;
namespace CompilerErrorRepro
{
// note: it appears the class has to have at least 2 generic type params to
fail.
public class MyClass&lt;T1, T2&gt;
{
// this {1.1} method decl is where the internal compiler error occurs.
// note: same error if {1.1} is removed and {1.2} uncommented:
// {1.1}
public T1 DoSomething(T2 data)
{
DoSomething(() =&gt; data);
return default(T1);
}
// {1.2}
// public void DoSomething(T2 data)
// {
// DoSomething(() =&gt; data);
// }
// note: comment out either of the following two overloads
// to prevent the internal compiler error
// {2}
public void DoSomething(Func&lt;T2&gt; valueExpression)
{
}
//note: no internal compiler error with this:
// public void DoSomething(Func&lt;T1, T2&gt; valueExpression)
// but there is an error with the following:
// {3}
public void DoSomething&lt;TMethodSpecific&gt;(Func&lt;TMethodSpecific, T2&gt;
valueExpression)
{
}
}
}
