C# Dictionary Error CS0835 & CS0305

Help Studio
1

Hi,

I have an automation which was build in a 2022 Release of Studio and which throws me an error in 2023.10.0. The project is in C#, all Packages are updated

I have a dictionary <string,string> called dictChange which is initialized and filled with key/value pairs in an assign activity

dictChange = new Dictionary <string,string>()
{
{“Value1”, variable1},
{“Value2”, variable2},
…
{“Value19”, variable19}
}

Since 2023.10.0 I have 2 errors at compilation:

CS0835: Cannot convert lambda to an expression tree whose argument 'Funct189<string,string…
CS0305> using the generic type’Func189<T0,T1… requires 21 type arguments

When I suppress any 5 key/value pairs, the error disappears and I can compile

I was even able to reproduce the error on another dev station with 2023.4.5 installed as my workflow is on an internal station and I am not authorized to post the original flow.

Hi,

In my environment (23.12.0 CE), it works without any error.

Did you find a resolution to this? I am running into the same issue when passing a Dictionary<string,Dictionary<string,object>> w/ 16 key/value pairs to a library activity for creating fixed width files.
The error is as follows:

Argument ‘Value’: CS0305: Using the generic type ‘Func45<T0, T1, T2, T3, T4, T5, T6, T7, T8, T9, T10, T11, T12, T13, T14, T15, TResult>’ requires 17 type arguments
Argument ‘Value’: CS0835: Cannot convert lambda to an expression tree whose type argument ‘Func45<string, string, string, string, string, string, string, string, string, string, string, string, string, string, Dictionary<string, Dictionary<string, object>>>’ is not a delegate type

The dictionary is as follows:

new Dictionary<string, Dictionary<string, object>> () {
