Hi @lpsandaruwan, thanks for the PR! I've just tried your branch and giving you some feedback below:

I did compiled the repo (npm run build), and used the following command to generate the output for the Enums.ts file you've created:

./bin/schema-codegen test/codegen/sources/Enums.ts --csharp --output codegen/enum/

I noticed the generated codegen/enum/ShipType.cs file had incorrect types and values:

public struct ShipType {
	public const string Transport = undefined;
	public const string Miner = undefined;
	public const string Colonizer = undefined;
}

The expected output for ShipType would be:

public struct ShipType {
	public const int Transport = 0;
	public const int Miner = 1;
	public const int Colonizer = 2;
}

---

The MessageType had the correct types and values:

public struct MessageType {
	public const string DeployMiner = "deploy-miner";
	public const string ColonizePlanet = "colonize-planet";
}

---

Lastly, I've tried adding another enum declaration on Enums.ts file (with fixed values rather than inferred as ShipType is)

export enum ShipType {/* ... */}
export enum MessageType {/* ... */}

export enum FixedValueEnum {
    One = 1,
    Two = 2,
    Three = 3,
}

After running schema-codegen again, the FixedValueEnum did not get generated, but their fields got appended to the MessageType structure:

public struct MessageType {

	public const string DeployMiner = "deploy-miner";
	public const string ColonizePlanet = "colonize-planet";
	public const string One = 1;
	public const string Two = 2;
	public const string Three = 3;
}

On this case, it should've defined a FixedValueEnum file with the contents:

public struct FixedValueEnum {
	public const int One = 1;
	public const int Two = 2;
	public const int Three = 3;
}

Please let me know if you have any question, happy to discuss them! Cheers
