1.2.0 release

[sergeybykov]

Here's what I think we need to target for the 1.2.0 release.

1. 1. Complete Feature: Server-side request interceptor (#749) #963, so that we are done with interceptors
2. 2. Complete EventHubStreamProvider checkpointing #1375 to have a first usable version of the EventHub stream adapter
3. 3. Provide enough helper methods (similar to Added helper methods for programmatic test configurations. #1411) for clean and easy programmatic configuration.
4. 4. Prepare a [WIP] PR with samples updated to 1.2.0 #1439 The litmus test for 3 is ability to convert all samples to programmatic config and remove all config files from them. Updated sample will have to wait in a [WIP] PR ready to be merged after we publish 1.2.0 NuGets.
5. 5. Converge Templates NuGet packages #1145 Add a single codegen NuGet, and turn the existing "template" NuGets into empty meta-packages.
6. 6. Update VSIX project templates to reference new codegen NuGet package #1437 Update VSIX interface and implementation project templates to use the new codegen NuGet package from 5. Samples in 4 should be updated to use these templates.
7. 7. Update Dev/Test Host VSIX template to use programmatic config. #1438 Update VSIX dev/test host template to use programmatic config instead of config files. Samples in 4 should be updated to use this template.
8. 8. Complete Transparently propagate exceptions to callers without modification #1378 since this may be a breaking change for people explicitly catching and unwrapping AggregateException.
9. 9. Fix VSIX project templates for VB and F# #1440 Fix VSIX project templates for VB and F#
10. 10. AzureQueueStreamProvider violates at-least-once delivery #1416 AzureQueueStreamProvider violates at-least-once delivery
11. 11. Remove dead client producer from pub sub #1429 Remove dead client producer from pub sub
12. 12. Stream consumers on lost clients #1669 Stream consumers on lost clients

We'll publish a beta of 1.2.0 NuGets for a short testing period (a week?)

Did I miss something important?

[jdom]

exception propagation (#1378) is almost finished by #1415, but I think it's worth making sure it goes into 1.2.0, since it's a breaking change we want to do as early as possible

[sergeybykov]

@jdom Agreed. Added as 8 to the list.

[sergeybykov]

Added 9 for #1440 Fix VSIX project templates for VB and F#.

[gabikliot]

It would be nice to include #1416. If we can agree with @jason-bragg on the strategy, I can quickly fix it.

[sergeybykov]

@gabikliot Added as 10.

[gabikliot]

I think @jason-bragg will have the fix for #1429 ready for this release.

[sergeybykov]

Yeah, I already added it as 11.

[sergeybykov]

Released.
