TextTemplating | Text templating is used to dynamically render contents

I work on an open-source application that is built in VisualStudio using the v142 toolset. This toolset is choosen over the newer v143 toolset because

• some external libraries provide binary distributions for v142
• github actions provide a runner containing v142

New developers of course start with VisualStudio 2022 CE. They just have to install the correct toolset and the compilation succeeds as expected. However, when building the installer (using Wix) it complains that the merge module for v142 is not available:

I've encountered NuGet problems while building DirectX-Graphics-Samples

The error occurs with many projects, here is an example:

I'm a little confused about compatibilities between netstandard, netframework, netX and how mono fits into the picture...

I understand that Rider's T4 engine runs on mono, but does that mean I can't use net5.0 assemblies in my T4 templates?

Currently, I have a net5.0 project, referencing net5.0 nuget assemblies.

In my T4 templates, I'm referencing the assembly DLLs in bin/Debug/net5.0 with `<@ assembly name="...">

When I run the T4 templates in-proc in a net5.0 Console Application via Mono.TextTemplating.TemplateGenerator.TemplateGenerator, then the templates work.

However, if I right-click a template in the Solution explorer and select 'Run Template', I get a list of errors that core System.* libs are missing, e.g.

I'm aware that I can install vs2019 by checking the option in GUI interaction. Actually, I've setup a box this way. I'm trying another way.

Per ms doc I can do the job from command line.

I'm trying to write a class in .Net Core using the Roslyn compiler to compile my project and return me the ClassDefinitions in that project. I am going to use that information to generate code using T4.

It's a .Net Core 3.1 project.

I can't find any good documentation on what packages I should use to accomplish this.

In the Solution getter after loading the Solution I get no documents in the Documents property and 1 Diagnostic message for each project it is trying to load:

Typing in Visual Studio feels often very sluggish. Like I'm typing in mud. I tried researching this forever on Google, but can't find a cause.

I have a high performance laptop that has no problems with running other tools. I have the feeling that it wasn't a problem in the beginning.

Is there somehow that I can debug performance of Visual Studio itself? Maybe it's some rogue extension or option that I can disable, because I don't use it anyway.

After every letter I type I see VS starts "low running background tasks" light up:

Despite that I assume it shouldn't have influence on typing performance, I want to exclude everything.

I also found the Performance Manager, but it seems to be empty:

Question:

Is there any way to debug VS performance myself? To i.e. find rogue settings or extensions?

Update:

As asked by @rustyx, here is an export. I use at the moment VS 2019 Preview - but I'm having the same problems with the normal release. Should be pretty vanilla.

I'm Trying to Transform T4 Template using MSBUILD , but I'm getting the following error
