> Thrift compiler generate code that doesn't compile netstd: object doesn't
> have ToString(StringBuilder) overload.
> Test case:
> {code}
> struct Test {
> 1: string test_string
> 2: i64 test_i64
> 3: binary test_binary
> 4: map<string, string> test_map
> }
> {code}
> produces following ToString() method:
> {code:c#}
> public override string ToString()
> {
> var sb = new StringBuilder("Test(");
> int tmp6 = 0;
> if((Test_string != null) && __isset.test_string)
> {
> if(0 < tmp6++) { sb.Append(", "); }
> sb.Append("Test_string: ");
> Test_string.ToString(sb);
> }
> if(__isset.test_i64)
> {
> if(0 < tmp6++) { sb.Append(", "); }
> sb.Append("Test_i64: ");
> Test_i64.ToString(sb);

> {code}
> Test_string.ToString(sb); (and folllowing .ToString(sb)) - produces build
