Get list of .csproj in directory and subdirectories of D:reposMTest

[1] PS D:reposMTest> ls -r -filter "*.csproj" | select Directory, Name

Sample output

Directory                       Name
---------                       ----
D:reposMTestM.Common        M.Common.csproj
D:reposMTestM.Mocks         M.Mocks.csproj
D:reposMTestM.StateMachines M.StateMachines.csproj

Get list of files containing line(s) that match <ProjectReferences*Include="([^"]+)" in directory and subdirectory

[2] PS D:reposMTest> ls | sls '<ProjectReferences*Include="([^"]+)"' | ForEach-Object {New-Object PSObject -Property @{Project=$_.Filename; DirectDep=$_.Matches.Groups[1].Value}}

Sample output

Project                DirectDeps
-------                ----------
dirs.proj              D:reposMTestM.Common
dirs.proj              D:reposMTestM.Mocks.csproj
dirs.proj              D:reposMTestM.StateMachines.csproj
M.Common.csproj        D:reposSCommonCommon.csproj
M.Common.csproj        D:reposQContractsContracts.csproj
M.Mocks.csproj         D:reposSControllerController.csproj
M.StateMachines.csproj D:reposMCommonCommon.csproj
M.StateMachines.csproj D:reposTAuthAuth.csproj

Questions

Q1: How can I feed the output of [1] to [2] to limit [2]’s search to .csproj files (i.e. exclude dirs.proj) to get the following output

Project                DirectDeps
-------                ----------
M.Common.csproj        D:reposSCommonCommon.csproj
M.Common.csproj        D:reposQContractsContracts.csproj
M.Mocks.csproj         D:reposSControllerController.csproj
M.StateMachines.csproj D:reposMCommonCommon.csproj
M.StateMachines.csproj D:reposTAuthAuth.csproj

Q2: And then how can I take that and make it group by Project/Filename? To get the following output (or similar)

M.Common.csproj, D:reposSCommonCommon.csproj, D:reposQContractsContracts.csproj
M.Mocks.csproj, D:reposSControllerController.csproj
M.StateMachines.csproj, D:reposMCommonCommon.csproj, D:reposTAuthAuth.csproj

Attempts

Attempts @ Q1

• ls -r -filter "*.csproj" | ForEach-Object {"$_.Directory$_.Name"}
• ls -r -filter "*.csrpoj" | select Path

Attempts @ Q2

• ls | sls '<ProjectReferences*Include="([^"]+)"' | ForEach-Object {New-Object PSObject -Property @{Project=$_.Filename; DirectDep=$_.Matches.Groups[1].Value}} | group Project
• ls | sls '<ProjectReferences*Include="([^"]+)"' | ForEach-Object {New-Object PSObject -Property @{Project=$_.Filename; DirectDep=$_.Matches.Groups[1].Value}} | group Project | select Name, Group
• ls | sls '<ProjectReferences*Include="([^"]+)"' | ForEach-Object {New-Object PSObject -Property @{Project=$_.Filename; DirectDep=$_.Matches.Groups[1].Value}} | group Project | select Name, Group.DirectDep

The second of the 3 has the closet output to what I’m looking for

Name                   Group
----                   -----
dirs.proj              {@{Project=dirs.proj; DirectDep=...M.Common.csproj}, {Project=dirs.proj; DirectDep=...M.Mocks.csproj}, {Project=dirs.proj; DirectDep=...M.StateMachines.csproj}
M.Common.csproj        {@{Project=M.Common.csproj; DirectDep=...Common.csproj}, {Project=M.Common.csproj; DirectDep=...Contracts.csproj}}
M.Mocks.csproj         {@{Project=M.Mocks.csproj; DirectDep=...Controller.csproj}
M.StateMachines.csproj {@{Project=M.StateMachines.csproj; DirectDep=...Common.csproj}, {Project=M.StateMachines.csproj; DirectDep=...Auth.csproj}}
