1. Ensure that you are using the right version of the SDK.

2. Try compiling in different .NET frameworks (4.6.1 and 4.5.2)

3. Clean and recompile your code?

Hi,

If I am not wrong, 'DeleteRecordChangeHistoryRequest' was introduced in V9.0. So in order to use this, you need to have Dynamics 365 V9 and the relevant dll's for V9+.

Hope this helps.

Thanks for your response.

But Microsoft.Crm.Sdk is available only up to version 7.1.0 in VS 2017 nuget packages. So How Can I install the same DLL with version 9.1? Please help me out.

Hi,

You can use Microsoft.Crm.Sdk.Proxy.dll . Refer below articles.

I have already updated Microsoft.crmsdk.coreAssemblies to V9.0.2.5 and Microsoft.CrmSdk.Deployment to V9.0 but that is not helping me to get the class 'DeleteRecordChangeHistoryRequest'.

Make sure that you include 'Microsoft.Crm.Sdk.Messages' and have a version 9.0 of the Microsoft.Crm.Sdk.Proxy DLL

Just verified this and it works.

Ensure that you clean and then rebuild your solution.

Let us know if you are still facing issues.

Yes, I have included 'Microsoft.Crm.Sdk.Messages' but 'Microsoft.Crm.Sdk.Proxy DLL' showing version up to 7.1.0. In my visual studio 2017 enterprise, version 9.0 for 'Microsoft.Crm.Sdk.Proxy DLL' is not available.

Hi,

This is because you are using CRM 2015 version. Can you please use the one which I shared above and try it with that. As suggested above by all, this is related to mismatch and you need to include the v9 sdk.

Hope this helps.
