Run command Script to execute linq script and get HTML leads to incomplete HTML on async void main

Mart · July 1

i try to save the result of an run linqpadscript (lprun) as Windows Task to html file.
Sometime the html is incomplete.

a) Working sample
When i run
main.linq
using (var queryExecutor = Util.Compile("mytestscript.ling"))
{
var executor = queryExecutor.Run(QueryResultFormat.Html);
executor.Wait();
var result = executor.AsString();
result.Dump();
....
myTestscript.linq

public void (){
MyTest();
}

MyTest(){
grid().Dump();
"Info".Dump();
}

I get as result.Dump() =>
htmlheader
html

b) Make testscript async - not working

myTestscript.linq

async task void (){
await MyTestasync();
// MyTestasync.Wait() also not working
}

async task MyTestAsync(){
"Info".Dump();
await gridAsync().Dump();

}

the result is in incomplete html without htmlheader. It starts direct with the output:
"Info" < br > ...

does it need some kind of UI Synchronization?
